Good news: midlife health is about more than a waist measurement. Here’s why

<p><em><a href="https://theconversation.com/profiles/rob-newton-12124">Rob Newton</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p>You’re not in your 20s or 30s anymore and you know regular health checks are important. So you go to your GP. During the appointment they measure your waist. They might also check your weight. Looking concerned, they recommend some lifestyle changes.</p> <p>GPs and health professionals commonly <a href="https://theconversation.com/the-body-mass-index-cant-tell-us-if-were-healthy-heres-what-we-should-use-instead-211190">measure waist circumference</a> as a vital sign for health. This is a better indicator than body mass index (BMI) of the amount of intra-abdominal fat. This is the really risky fat around and within the organs that can drive heart disease and metabolic disorders such as type 2 diabetes.</p> <p>Men are at greatly increased risk of health issues if their waist circumference is <a href="https://www.bmj.com/content/311/7017/1401">greater than 102 centimetres</a>. Women are considered to be at greater risk with a waist circumference of <a href="https://www.bmj.com/content/311/7017/1401">88 centimetres or more</a>. More than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">two-thirds of Australian adults</a> have waist measurements that put them at an increased risk of disease. An even better indicator is waist circumference divided by height or <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease.">waist-to-height ratio</a>.</p> <p>But we know people (especially women) have a propensity to <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">gain weight around their middle during midlife</a>, which can be very hard to control. Are they doomed to ill health? It turns out that, although such measurements are important, they are not the whole story when it comes to your risk of disease and death.</p> <h2>How much is too much?</h2> <p>Having a waist circumference to height ratio larger than 0.5 is associated with greater risk of chronic disease as well as premature death and this applies in adults of any age. A healthy waist-to-height ratio is between 0.4 to 0.49. A ratio of 0.6 or more <a href="https://www.baker.edu.au/news/in-the-media/waist-height-ratio#:%7E:text=According%20to%20research%2C%20a%20healthy,the%20highest%20risk%20of%20disease">places a person at the highest risk of disease</a>.</p> <p>Some experts recommend <a href="https://www.nature.com/articles/s41574-019-0310-7">waist circumference be routinely measured in patients during health appointments</a>. This can kick off a discussion about their risk of chronic diseases and how they might address this.</p> <p>Excessive body fat and the associated health problems manifest more strongly during midlife. A range of social, personal and physiological factors come together to make it more difficult to control waist circumference as we age. Metabolism tends to slow down mainly due to decreasing muscle mass because people do <a href="https://onlinelibrary.wiley.com/doi/10.1002/jcb.25077">less vigorous physical activity, in particular resistance exercise</a>.</p> <p>For women, hormone levels begin changing in mid-life and this also <a href="https://www.tandfonline.com/doi/full/10.3109/13697137.2012.707385">stimulates increased fat levels particularly around the abdomen</a>. At the same time, this life phase (often involving job responsibilities, parenting and caring for ageing parents) is when elevated stress can lead to <a href="https://journals.lww.com/psychosomaticmedicine/abstract/2000/09000/stress_and_body_shape__stress_induced_cortisol.5.aspx">increased cortisol which causes fat gain in the abdominal region</a>.</p> <p>Midlife can also bring poorer sleep patterns. These contribute to fat gain with <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0010062">disruption to the hormones that control appetite</a>.</p> <p>Finally, your family history and genetics can <a href="https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1002695">make you predisposed to gaining more abdominal fat</a>.</p> <h2>Why the waist?</h2> <p>This intra-abdominal or visceral fat is much more metabolically active (it has a greater impact on body organs and systems) than the fat under the skin (subcutaneous fat).</p> <p>Visceral fat surrounds and infiltrates major organs such as the liver, pancreas and intestines, releasing a variety of chemicals (hormones, inflammatory signals, and fatty acids). These affect inflammation, lipid metabolism, cholesterol levels and insulin resistance, <a href="https://academic.oup.com/eurheartjsupp/article/8/suppl_B/B4/461962">contributing to the development of chronic illnesses</a>.</p> <p>The issue is particularly evident <a href="https://www.ajog.org/article/S0002-9378(19)30588-5/abstract">during menopause</a>. In addition to the direct effects of hormone changes, <a href="https://www.sciencedirect.com/science/article/pii/S0960076013001118?via%3Dihub">declining levels of oestrogen change brain function, mood and motivation</a>. These psychological alterations can result in reduced physical activity and increased eating – often of comfort foods high in sugar and fat.</p> <p>But these outcomes are not inevitable. Diet, exercise and managing mental health can limit visceral fat gains in mid-life. And importantly, the waist circumference (and ratio to height) is just one measure of human health. There are so many other aspects of body composition, exercise and diet. These can have much larger influence on a person’s health.</p> <h2>Muscle matters</h2> <p>The quantity and quality of skeletal muscle (attached to bones to produce movement) a person has makes a <a href="https://www.nature.com/articles/nrendo.2012.49">big difference</a> to their heart, lung, metabolic, immune, neurological and mental health as well as their physical function.</p> <p>On current evidence, it is equally or more important for health and longevity to <a href="https://www.bmj.com/content/345/bmj.e7279">have</a> higher muscle mass and better cardiorespiratory (aerobic) fitness than waist circumference within the healthy range.</p> <p>So, if a person does have an excessive waist circumference, but they are also sedentary and have less muscle mass and aerobic fitness, then the recommendation would be to focus on an appropriate exercise program. The fitness deficits should be addressed as priority rather than worry about fat loss.</p> <p>Conversely, a person with low visceral fat levels is not necessarily fit and healthy and may have quite poor aerobic fitness, muscle mass, and strength. <a href="https://bjsm.bmj.com/content/45/6/504">The research evidence</a> is that these vital signs of health – how strong a person is, the quality of their diet and how well their heart, circulation and lungs are working – are more predictive of risk of disease and death than how thin or fat a person is.</p> <p>For example, a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5510687/">2017 Dutch study</a> followed overweight and obese people for 15 years and found people who were very physically active had no increased heart disease risk than “normal weight” participants.</p> <h2>Getting moving is important advice</h2> <p>Physical activity has many benefits. Exercise can counter a lot of the negative behavioural and physiological changes that are occurring during midlife including for people going through menopause.</p> <p>And regular exercise reduces the tendency to use food and drink to help manage what can be a <a href="https://journals.lww.com/acsm-msse/fulltext/2008/05000/physical_activity,_sedentary_index,_and_mental.7.aspx">quite difficult time in life</a>.</p> <p>Measuring your waist circumference and monitoring your weight remains important. If the measures exceed the values listed above, then it is certainly a good idea to make some changes. Exercise is effective for fat loss and in particular <a href="https://bjsm.bmj.com/content/57/16/1035">decreasing visceral fat</a> with greater effectiveness when <a href="https://bmcwomenshealth.biomedcentral.com/articles/10.1186/s12905-019-0864-5">combined with dietary restriction of energy intake</a>. Importantly, any fat loss program – whether through drugs, diet or surgery – is also a muscle loss program unless resistance exercise is part of the program. Talking about your overall health with a doctor is a great place to start.</p> <p><a href="https://www.essa.org.au/Public/Public/Searches/find-aep-withdistance.aspx">Accredited exercise physiologists</a> and <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">accredited practising dietitians</a> are the most appropriate allied health professionals to assess your physical structure, fitness and diet and work with you to get a plan in place to improve your health, fitness and reduce your current and future health risks.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226019/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/rob-newton-12124"><em>Rob Newton</em></a><em>, Professor of Exercise Medicine, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eating some chocolate really might be good for you – here’s what the research says

<p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year.</p> <p>It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you?</p> <p>Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state.</p> <p>In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs.</p> <p>Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue.</p> <p>One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals.</p> <p>These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals.</p> <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal.</p> <p>Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks.</p> <h2>Health benefits of cocoa</h2> <p>There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido.</p> <p>These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes.</p> <p>Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels.</p> <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart.</p> <p>Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>.</p> <h2>Chocolate toxicity</h2> <p>As much as chocolate might be considered a medicine for some, it can be a poison for others.</p> <p>It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures.</p> <p>The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms.</p> <p>Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>.</p> <p>Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones.</p> <p>So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits.</p> <p>A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high.</p> <p>But whatever chocolate you go for, please don’t share it with the dog.<!-- Below is The Conversation's page counter tag.

Sunscreen: why wearing it even in winter could be a good idea

<p><em><a href="https://theconversation.com/profiles/karl-lawrence-404481">Karl Lawrence</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p>Sunscreen has taken centre stage in many skincare routines, especially among those hoping to prevent visible signs of ageing. But while it makes sense to wear sunscreen every day in the summer when the sun’s rays are most powerful, many may wonder whether there’s any benefit of wearing sunscreen daily in the winter months.</p> <p>The sun’s radiation can reach us during all times of the year. This means that in both summer and winter, we are exposed to infrared radiation, as well as UVA and UVB rays.</p> <p>UVB is mainly responsible for sunburn and DNA damage – and can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3709783/">cause skin cancers</a> as a result of long-term exposure. UVA radiation does contribute to these processes somewhat, but it’s less effective at doing so. UVA can penetrate deeper into the skin, however, which can damage the collagen – a key part of the skin that keeps it firm and elastic. This can cause the <a href="https://pubmed.ncbi.nlm.nih.gov/25234829/">skin to age faster</a>, leading to wrinkles, fine lines and changes in pigmentation.</p> <p>The amount of UVA and UVB radiation that reaches the Earth’s surface changes across the seasons. This is due to the angle of the Sun in the sky, as well as other factors such as latitude and time of day.</p> <p>For example, let’s compare how <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/php.12422">UVA and UVB radiation varies</a> at solar noon in London, UK and Kuala Lampur, Malaysia (which is near the equator).</p> <p>In latitudes closer to the equator (such as in Kuala Lampur), the amount of UVA and UVB radiation throughout the year remains fairly consistent. But in higher latitudes, such as London, there’s almost no UVB radiation throughout the winter months – whereas there’s still some UVA radiation.</p> <p>Not only that, but people living further from the equator may tend to spend less time exposed to the Sun in winter due to the colder temperatures and variable weather. And when they do go outside, they may cover their skin up – usually leaving only their face exposed to the Sun for much shorter periods of time.</p> <p>But UVA radiation can still penetrate through clouds and windows. While our exposure to these rays is probably minimal, skin damage from UV exposure is <a href="https://www.sciencedirect.com/science/article/pii/S0079610706000162">accumulated over decades</a>, so anything that can be done to reduce exposure (and damage) over time may be beneficial. This is also true of UVB exposure – although it is less relevant in winter months at higher latitudes.</p> <p>This may be where daily sunscreen use during the winter is still of benefit. Sunscreens are formulated to reduce exposure to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6978633/">both UVB and UVA rays</a> – although they are usually more effective at reducing exposure to UVB radiation. They have been designed in this way to prevent the most damaging effects of the Sun, such as sunburn and DNA damage. The impact of exposure to UVA radiation has only been considered more recently.</p> <p>Numerous studies have shown regular sunscreen use over many years is effective at <a href="https://onlinelibrary.wiley.com/doi/10.1111/phpp.12109">preventing skin damage</a>, photoaging and skin cancers. The most robust trials suggest daily sunscreen use is most effective, but this will be dependent on the factors discussed above.</p> <h2>The effects of altitude and snow</h2> <p>One place where winter sunscreen use is especially important is when skiing or snowboarding – or when you’re otherwise going to be outside for extended periods of time, at higher altitudes on snow-covered mountains.</p> <p>Both altitude and snow can increase the doses of <a href="https://www.who.int/news-room/questions-and-answers/item/radiation-ultraviolet-(uv)">UVA and UVB radiation</a> a person receives. Snow can reflect up to 80% of UV radiation emitted by the Sun – effectively almost doubling the doses received. Also, for every 1,000-foot increase in altitude, there’s a 10% increase in UV exposure. This is why it’s essential to protect the skin and eyes by wearing sunscreen, protective clothing and sunglasses that block both types of UV ray. This is also true when spending time in snowy environments, such as when hiking or skating.</p> <p>Sunscreens are generally regarded as safe and tend to have few adverse effects, so you don’t need to worry too much about wearing one throughout the year. However, there are some points to consider, especially if you have skin conditions. For example, sunscreen can <a href="https://www.byrdie.com/does-sunscreen-cause-acne-or-help-it-7546147">exacerbate acne</a> and cause <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7759112/">irritation and allergic reactions</a> – although these are rare.</p> <p>There are also emerging concerns from regulatory agencies about the <a href="https://jamanetwork.com/journals/jama/fullarticle/2759002">absorption of UV filters into the body</a>. However, the consequences of such absorption and the potential affects on health are not well defined and require more research.</p> <p>Still, the benefits of sunscreen have been widely demonstrated – as has their safety. So if you want to prevent premature signs of ageing, it’s important to use sunscreen at all times you may be exposed to the Sun – especially in the summer months. While the benefits of wearing sunscreen in winter are less well defined, there’s probably no harm in wearing one if you want to.</p> <p>If you decide to use sunscreen in winter, use ones that have broad spectrum five-star UVA protection. For day-to-day use, high SPF sunscreens are unlikely to provide a large benefit, particularly if spending only short periods outside. However, if skiing, a <a href="https://www.jaad.org/article/S0190-9622(17)31086-1/fulltext">high-SPF sunscreen</a> with five-star UVA protection would be beneficial.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/219640/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/karl-lawrence-404481"><em>Karl Lawrence</em></a><em>, Research fellow, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p><em>Image credits: </em><em>Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The US just returned to the Moon after more than 50 years. How big a deal is it, really?

<p><em><a href="https://theconversation.com/profiles/david-flannery-3906">David Flannery</a>, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a></em></p> <p>In the few short years since the COVID pandemic changed our world, China, Japan and India have all successfully landed on the Moon.</p> <p>Many more robotic missions have flown past the Moon, entered lunar orbit, or crashed into it in the past five years. This includes <a href="https://www.planetary.org/space-missions/kplo">spacecraft developed by South Korea</a>, <a href="https://english.alarabiya.net/News/gulf/2023/04/27/Dubai-s-ruler-announces-new-moon-mission-after-UAE-s-Rashid-Rover-lunar-crash-">the United Arab Emirates</a>, and an <a href="https://www.spaceil.com/">Israeli not-for-profit organisation</a>.</p> <p>Late last week, the American company <a href="https://www.intuitivemachines.com/">Intuitive Machines</a>, in collaboration with NASA, celebrated “America’s return to the Moon” with a successful landing of its Odysseus spacecraft.</p> <p>Recent <a href="https://theconversation.com/change-5-china-launches-sample-return-mission-to-the-moon-is-it-winning-the-new-space-race-150665">Chinese-built sample return missions</a> are far more complex than this project. And didn’t NASA ferry a dozen humans to the Moon back when microwaves were cutting-edge technology? So what is different about this mission developed by a US company?</p> <h2>Back to the Moon</h2> <p>The recent Odysseus landing stands out for two reasons. For starters, this is the first time a US-built spacecraft has landed – not crashed – on the Moon for over 50 years.</p> <p>Secondly, and far more significantly, this is the first time a private company has pulled off a successful delivery of cargo to the Moon’s surface.</p> <p>NASA has lately focused on destinations beyond the Earth–Moon system, including Mars. But with its <a href="https://www.nasa.gov/commercial-lunar-payload-services/">Commercial Lunar Payload Services</a> (CLPS) program, it has also funded US private industry to develop Moon landing concepts, hoping to reduce the delivery costs of lunar payloads and allow NASA engineers to focus on other challenges.</p> <p>Working with NASA, Intuitive Machines selected a <a href="https://en.wikipedia.org/wiki/Malapert_(crater)">landing site</a> about 300 kilometres from the lunar south pole. Among other challenges, landing here requires entering a polar orbit around the Moon, which consumes additional fuel.</p> <p>At this latitude, the land is heavily cratered and dotted with long shadows. This makes it challenging for autonomous landing systems to find a safe spot for a touchdown.</p> <p>NASA spent about US$118 million (A$180 million) to land six scientific <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/About_Payload_Systems">payloads</a> on Odysseus. This is relatively cheap. Using low-cost lunar landers, NASA will have an efficient way to test new space hardware that may then be flown on other Moon missions or farther afield.</p> <h2>Ten minutes of silence</h2> <p>One of the technology tests on the Odysseus lander, NASA’s <a href="https://www.nasa.gov/directorates/stmd/impact-story-navigation-doppler-lidar/">Navigation Doppler Lidar experiment</a> or NDL, appears to have proved crucial to the lander’s success.</p> <p>As the lander neared the surface, the company realised its navigation systems had a problem. NASA’s NDL experiment is serendipitously designed to test precision landing techniques for future missions. It seems that at the last second, engineers bodged together a solution that involved feeding necessary data from NDL to the lander.</p> <p>Ten minutes of silence followed before a <a href="https://twitter.com/Int_Machines/status/1760838333851148442">weak signal was detected</a> from Odysseus. Applause thundered through the mission control room. NASA’s administrator released a video congratulating everyone for returning America to the Moon.</p> <p>It has since become clear the lander is not oriented perfectly upright. The solar panels are generating sufficient power and the team is slowly receiving the first images from the surface.</p> <p>However, it’s likely Odysseus <a href="https://www.universetoday.com/165864/odysseus-moon-lander-is-tipped-over-but-still-sending-data/">partially toppled over</a> upon landing. Fortunately, at the time of writing, it seems most of the science payload may yet be deployed as it’s on the side of the lander facing upwards. The unlucky payload element facing downwards <a href="https://edition.cnn.com/2024/02/23/world/odysseus-lunar-landing-sideways-scn/index.html">is a privately contributed artwork</a> connected <a href="https://edition.cnn.com/2024/02/22/style/jeff-koons-moon-phases-odysseus-landing/index.html">to NFTs</a>.</p> <p>The lander is now likely to survive for at least a week before the Sun sets on the landing site and a dark, frigid lunar night turns it into another museum piece of human technology frozen in the lunar <a href="https://www.britannica.com/science/regolith">regolith</a>.</p> <h2>Win some, lose some</h2> <p>NASA’s commercial approach to stimulating low-cost payload services all but guarantees some failures. But eventually NASA hopes that several commercial launch and landing providers will emerge from the program, along with a few learning experiences.</p> <p>The know-how accumulated at organisations operating hardware in space is at least as important as the development of the hardware itself.</p> <p>The market for commercial lunar payloads remains unclear. Possibly, once the novelty wears off and brands are no longer able to generate buzz by, for example, <a href="https://www.columbia.com/omni-heat-infinity/moon-mission/">sending a piece of outdoor clothing to the Moon</a>, this source of funding may dwindle.</p> <p>However, just as today, civil space agencies and taxpayers will continue to fund space exploration to address shared science goals.</p> <p> </p> <p>Ideally, commercial providers will offer NASA an efficient method for testing key technologies needed for its schedule of upcoming scientific robotic missions, as well as <a href="https://www.nasa.gov/specials/artemis/">human spaceflight in the Artemis program</a>. Australia would also have the opportunity to test hardware at a reduced price.</p> <p>It’s worth noting that US budgetary issues, <a href="https://spacenews.com/nasa-warns-of-very-problematic-space-technology-budget-cuts/">funding cuts</a> and <a href="https://www.jpl.nasa.gov/news/jpl-workforce-update">subsequent lay-offs</a> do threaten these ambitions.</p> <p>Meanwhile, in Australia, we may have nothing to launch anyway. We continue to spend less <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_departments/Parliamentary_Library/Budget/reviews/2023-24/ScienceResearch">than the OECD average on scientific research</a>, and only a few Australian universities – who traditionally lead such efforts – <a href="https://business.gov.au/grants-and-programs/moon-to-mars-initiative-demonstrator-mission-grants/grant-recipients">have received funding</a> provided by the Australian Space Agency.</p> <p>If we do support planetary science and space exploration in the future, Australians will need to decide if we want to allocate our limited resources, competing with NASA and US private industry, to supply launch, landing and robotic services to the global space industry.</p> <p>Alternatively, we could leverage these lower-cost payload providers to develop our own scientific space program, and locally developed space technologies associated with benefits to the knowledge economy, education and national security.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/224276/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/david-flannery-3906"><em>David Flannery</em></a><em>, Planetary Scientist, <a href="https://theconversation.com/institutions/queensland-university-of-technology-847">Queensland University of Technology</a></em></p> <p><em>Image credits: Intuitive Machines</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Good luck!": Pink stops show as pregnant fan goes into labour

<p>It's not every day that you can say pop icon Pink stopped her show as you were going into labour, but for one Sydney fan this was her reality. </p> <p>The <em>So What </em>singer briefly stopped her show after spotting a pregnant woman getting wheeled out of her concert by a medic on Friday. </p> <p>Wanting to know what all the commotion was about, Pink stopped half way through her performance of <em>Our Song </em>and excitedly tried to find out the baby-to-be's gender, after discovering  that the concertgoer was experiencing contractions. </p> <p>"Is it Alicia or Alex being born?" she asked from the stage, referencing her birth name, Alecia Beth Moore. </p> <p>The singer then playfully said that they shouldn't "be looking" anymore and urged the crowd to give the woman some "privacy."</p> <p> </p> <div class="embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; outline: none !important; width: 573px; max-width: 100%;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7333559856185593090&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40miss_chantal%2Fvideo%2F7333559856185593090&amp;image=https%3A%2F%2Fp16-sign-sg.tiktokcdn.com%2Fobj%2Ftos-alisg-p-0037%2F22874a6d4d174a149b284ecb5a642be4_1707477473%3Fx-expires%3D1707865200%26x-signature%3DNsu2Nw7zUT%252Bf6ndURt3fjSjaZfg%253D&amp;key=59e3ae3acaa649a5a98672932445e203&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>"Wow, Our Song, that was the one that did it.

What are ‘good’ and ‘bad’ debts, and which should I pay off first?

<p><em><a href="https://theconversation.com/profiles/angel-zhong-1204643">Angel Zhong</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>With the cost of living soaring and many struggling to get a pay rise, it’s not surprising people are using debt to navigate life’s financial twists and turns.</p> <p>Owing money can sometimes feel challenging, but not all debts should keep you awake at night.</p> <p>So which debts are good and which are bad? And in what order should you pay them off? As it all depends on your personal circumstances, all I can offer is general information and not financial advice. Ideally, you should seek guidance from an accredited financial adviser. But in the meantime, here are some ideas to consider.</p> <h2>What is a ‘good debt’?</h2> <p>Good debts can be strategic tools and help build a solid foundation for your future. They usually increase your net worth by helping you generate income or buy assets that increase in value.</p> <p>With good debts, you usually get back more than what you pay for. They usually have lower interest rates and longer repayment terms. But personal finance is dynamic, and the line between good and bad debt can be nuanced. If not managed properly, even good debts can cause problems.</p> <p>Some examples of “good debts” might include:</p> <p><strong>Mortgages</strong>: A mortgage allows you to buy a house, which is an asset that generally increases in value over time. You may potentially get tax advantages, such as <a href="https://www.ato.gov.au/forms-and-instructions/rental-properties-2023/other-tax-considerations">negative gearing</a>, through investment properties. However, it’s crucial not to overstretch yourself and turn a mortgage into a nightmare. As a rule of thumb, try avoid spending <a href="https://www.cnbc.com/select/mortgage-affordability/">more than 30% of your income</a> per year on your mortgage repayments.</p> <p><strong>Student loans</strong>: Education is an investment in yourself. Used well, student loans (such as <a href="https://www.studyassist.gov.au/help-loans/hecs-help">HECS-HELP</a>) can be the ticket to a higher-paying job and better career opportunities.</p> <h2>What is a ‘bad debt’?</h2> <p>“Bad debts” undermine your financial stability and can hinder your financial progress. They usually come with high interest rates and short repayment terms, making them more challenging to pay off. They can lead to a vicious cycle of debt.</p> <p>Examples of bad debts include:</p> <p><strong>Payday loans</strong>: A payday loan offers a quick fix for people in a financial tight spot. However, their steep interest rates, high fees and tight repayment terms often end up worsening a person’s financial problems. The interest and fee you may end up paying can get close to the loan amount itself.</p> <p><strong>Credit card debt:</strong> Credit cards can be like quicksand for your finances. If you don’t pay off your purchase on time, you’ll be subject to an annual interest rate of around <a href="https://www.rba.gov.au/statistics/tables/">19.94%</a>. For a A$3,000 credit card debt, for example, that could mean paying nearly $600 annual interest. Carrying credit card debt from month to month can lead to a seemingly never-ending debt cycle.</p> <p><strong>Personal loans:</strong> People usually take personal loans from a bank to pay for something special, such as a nice holiday or a car. They often come with higher interest rates, averaging around <a href="https://www.finder.com.au/personal-loans">10%</a>. Spending money that you don’t have can lead to prolonged financial headaches.</p> <p><strong>Buy-now-pay-later services:</strong> Buy-now-pay-later services often provide interest-free instalment options for purchases. This can be tempting, but the account fees and late payment fees associated with buy-now-pay-later services can lead to a long-term financial hangover. The convenience and accessibility of buy-now-pay-later services can also make it easy to get further and further into debt.</p> <h2>So in what order should I pay off my debts?</h2> <p>There is no one right answer to this question, but here are three factors to consider.</p> <p><strong>Prioritise high-interest debts</strong>: Start by confronting the debts with the highest interest rates. This typically includes credit card debt and personal loans. Paying off high-interest debts first can save you money and reduce your total debt faster.</p> <p><strong>Negotiate interest rates or switch lenders:</strong> Don’t be shy. A simple call to your lender requesting a lower rate can make a significant difference. You may also take advantage of sign-on offers and refinancing your loan with a new lender. In the banking business, customers are not usually rewarded for their loyalty.</p> <p><strong>Consider different repayment strategies:</strong> Choose a debt repayment strategy that aligns with your preferences. Some people get a psychological boost from paying off smaller debts first (this is often called the “<a href="https://www.wellsfargo.com/goals-credit/smarter-credit/manage-your-debt/snowball-vs-avalanche-paydown/#:%7E:text=The%20%22snowball%20method%2C%22%20simply,all%20accounts%20are%20paid%20off.">snowball method</a>”). Others focus on high-interest debts (often known as the “<a href="https://www.wellsfargo.com/goals-credit/smarter-credit/manage-your-debt/snowball-vs-avalanche-paydown/#:%7E:text=The%20%22snowball%20method%2C%22%20simply,all%20accounts%20are%20paid%20off.">avalanche method</a>”). Find what works for you. The most important thing is to have a plan and stick to it.</p> <p>Review the terms of each debt carefully. Certain loans offer flexibility in repayment schedules, while others may impose penalties for early settlement. Take note of these conditions as you develop your repayment plan.</p> <p>Debt can be a useful tool or a dangerous trap, depending on how you use it. By understanding the difference between good and bad debts, and by having a smart strategy for paying them off, you can take charge of your financial future.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/217779/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/angel-zhong-1204643"><em>Angel Zhong</em></a><em>, Associate Professor of Finance, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is the ‘sunk cost fallacy’? Is it ever a good thing?

<p><em><a href="https://theconversation.com/profiles/aaron-nicholas-1487960">Aaron Nicholas</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>Have you ever encountered a subpar hotel breakfast while on holiday? You don’t really like the food choices on offer, but since you already paid for the meal as part of your booking, you force yourself to eat something anyway rather than go down the road to a cafe.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/0167268180900517">Economists</a> and <a href="https://www.sciencedirect.com/science/article/pii/0749597885900494">social scientists</a> argue that such behaviour can happen due to the “sunk cost fallacy” – an inability to ignore costs that have already been spent and can’t be recovered. In the hotel breakfast example, the sunk cost is the price you paid for the hotel package: at the time of deciding where to eat breakfast, such costs are unrecoverable and should therefore be ignored.</p> <p>Similar examples range from justifying finishing a banal, half-read book (or half-watched TV series) based on prior time already “invested” in the activity, to being less likely to quit exclusive groups such as sororities and sporting clubs the more <a href="https://psycnet.apa.org/record/1960-02853-001">effort it took to complete the initiation ritual</a>.</p> <p>While these behaviours are not rational, they’re all too common, so it helps to be aware of this tendency. In some circumstances, you might even use it for your benefit.</p> <h2>Sunk costs can affect high-stakes decisions</h2> <p>While the examples above may seem relatively trivial, they show how common the sunk cost fallacy is. And it can affect decisions with much higher stakes in our lives.</p> <p>Imagine that Bob previously bought a house for $1 million. Subsequently, there’s a nationwide housing market crash. All houses are now cheaper by 20% and Bob can only sell his house for $800,000. Bob’s been thinking of upgrading to a bigger house (and they are now cheaper!), but will need to sell his existing house to have funds for a downpayment.</p> <p>However, he refuses to upgrade because he perceives a loss of $200,000 relative to the original price he paid of $1 million. Bob is committing the sunk cost fallacy by letting the original price influence his decision making – only the house’s current and projected price should matter.</p> <p>Bob might be acting irrationally, but he’s only human. Part of the reason we may find it difficult to ignore such losses is because losses are psychologically more salient relative to gains – this is known as <a href="https://psycnet.apa.org/record/1985-05780-001">loss aversion</a>.</p> <p>While most of the evidence for the sunk cost fallacy comes from <a href="https://link.springer.com/article/10.1007/s40685-014-0014-8">individual decisions</a>, it may also influence the decisions of groups. In fact, it is sometimes referred to as the <a href="https://www.nature.com/articles/262131a0">Concord fallacy</a>, because the French and British governments continued funding the doomed supersonic airliner long after it was likely it would not be commercially viable.</p> <p>Another example is drawn-out armed conflict that involves a large loss of lives for the losing side. Some may think it impossible to capitulate because the casualties will have “died in vain”.</p> <h2>Knowing about sunk costs can help you</h2> <p>If you find yourself justifying behaviour due to costs you’ve paid in the past rather than circumstances of the present, or predictions of the future, it’s worth checking yourself.</p> <p>Identifying sunk costs allows you to cut your losses early and move on, rather than perpetuating larger losses. This is apparent in the housing example: the larger the crash, the cheaper the bigger house; and yet the larger the crash, the greater the perceived loss from selling the existing house. Hence, the greater the loss in opportunity inflicted by the sunk cost fallacy.</p> <p>If you find it difficult to overcome the sunk cost fallacy, it may help to delegate such decisions to others. This may include the decision of whether to <a href="https://direct.mit.edu/rest/article-abstract/93/1/193/57894/The-Flat-Rate-Pricing-Paradox-Conflicting-Effects">go to a buffet</a> or subscribe to Netflix, with the latter potentially being a double whammy: one may feel compelled to binge-watch due to the flat fee structure and, as mentioned earlier, to finish mediocre series once halfway through.</p> <h2>Use sunk costs to your advantage</h2> <p>A second, less obvious benefit is actively using the fallacy to your advantage. For example, many gym memberships require upfront payments regardless of how much you use the facilities. If you find it hard to ignore sunk costs, choosing gym memberships that have large upfront fees and minimal pay-per-usage fees may be a way to <a href="https://pubsonline.informs.org/doi/abs/10.1287/mnsc.2018.3032">commit yourself</a> to a regular gym habit.</p> <p>This can also apply to other activities that involve short-term pain for long-term gain – for example, paying for an online course will make you more likely to stick with it than if you found a free course.</p> <p>But be warned, this doesn’t work for everything: it seems that spending wildly on a <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/ecin.12206">wedding ceremony or engagement ring</a> doesn’t have a “sunk cost” effect – it fails to increase the likelihood of staying married.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/217798/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/aaron-nicholas-1487960"><em>Aaron Nicholas</em></a><em>, Senior Lecturer in Economics, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Sweet secrets – the science of keeping good news hush hush

<p>Most people keep secrets, and staying hush about good news – like pregnancy, presents, proposals and promotions – tends to be freely chosen, enjoyable and energising according to new research.</p> <div class="copy"> <p>Conventional wisdom holds that secrecy is a burden, and good news is <a href="https://cosmosmagazine.com/health/body-and-mind/seeing-emotions/">meant to be shared</a>. But Australian and United States researchers <a href="https://dx.doi.org/10.1037/pspa0000352" target="_blank" rel="noopener">publishing</a> in the <em>Journal of Personality and Social Psychology</em> investigated the effects of keeping positive news to one’s self, finding the motivations and effects are quite different to other types of secrets.</p> <p>Associate Professor Katharine Greenaway researches <a href="https://cosmosmagazine.com/people/society/are-sciences-equal/">social psychology</a> at the University of Melbourne and is an author of the paper. She tells <em>Cosmos</em>: “secrecy is extremely common – on average, 97% of people are keeping a secret right now.” </p> <p>“It’s obviously fascinating to know, people’s secrets, and why they keep them,” she says. </p> <p>Greenaway adds studying secrecy is “really interesting theoretically because we’re social creatures. From our evolutionary past, we’ve always had to be social, we’ve had to communicate in order to co-operate. So, from that perspective it’s really interesting, why would we ever want to keep information from other people? […] It’s particularly interesting why we would keep positive information from others.” </p> <p>Across 5 different experiments involving 2,500 participants the researchers tested different elements of positive secrecy: the effect of secret and non-secret good news; deliberately keeping news secret for personal reasons compared to external reasons ; and the effects of positive secrets compared to other kinds of secrets.</p> <p>“Positive secrets, we’ve found, tend to be the types of secrets people choose freely, and they actually quite enjoy keeping,” Greenaway says.</p> <p>In one study, involving 194 people, participants were provided with a list of 38 common categories of good news, such as: pregnancy; won something; new possession; financial windfall; family news; and self-development. They were asked to indicate which items were relevant, and any they were keeping secret.</p> <p>On average, participants held 14 to 15 pieces of good news, keeping 5 to 6 positive items to themselves.</p> <p>A second study tested motivation. A new group of 600 participants in committed relationships were asked to imagine a plausible piece of good news (from the list of common good news). </p> <p>They were randomly assigned to imagine either: deciding to keep the news secret until they chose share it with their partner, or the information remaining unknown due to external factors like being in meetings all day. For a further group, no reason was specified for not sharing the news. Participants were then asked about how “tired, depleted, weak, passive, active, invigorated, strong, energized, awake and alert, and alive they felt” on a scale from not at all ‘1’ to very much ‘7’.</p> <p>When people elected to keep a piece of good news private, they felt energised. But when external factors got in the way of sharing information, they felt fatigued.</p> <p><iframe title="People are Seriously becoming Friends with their Robotic Vacuums" src="https://omny.fm/shows/huh-science-explained/people-are-seriously-becoming-friends-with-their-r/embed?in_playlist=podcast&amp;style=Cover" width="100%" height="180" frameborder="0"></iframe></p> <p>Three further experiments tested the effect of positive or negative secrets. Finding positive secrets were more likely to be kept for personal reasons, freely chosen, generating greater feelings of energy.</p> <p>“When people keep a positive secret as opposed to a different type of secret, they tend to have relatively more intrinsic motivation for doing so. Intrinsic motivation is associated with feeling like something is really important, personally valuable to you. And also enjoyable,” says Greenaway.</p> <p>“If you’ve kept a negative secret, often you’re worried about what would happen if that secret got out […] you feel as though that’s something that’s being imposed on you, as opposed to something that you’re freely choosing to keep secret from others.”</p> <p>Prior research has mostly focused on negative secrets, suggesting secrecy can be harmful.</p> <p>In contrast, this new research suggests holding on to positive news is more likely to be freely chosen, for personal reasons, and can be more energising than sharing the information.</p> <p><em>Image credits: Getty Images </em></p> <div> <p align="center"><noscript data-spai="1"><em>&amp;lt;img decoding="async" fetchpriority="high" class="aligncenter size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/q_lossy+ret_img+to_auto/cosmosmagazine.com/wp-content/uploads/2023/11/Cosmos-Catch-Up-embed_728x150-1.jpg" data-spai-egr="1" alt="Sign up to our weekly newsletter" width="600" height="154" title="sweet secrets - the science of keeping good news hush hush 2"&amp;gt;</em></noscript></p> </div> <p><em><!-- Start of tracking content syndication.

What is the OMAD diet? Is one meal a day actually good for weight loss? And is it safe?

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>What do British Prime Minister <a href="https://www.sciencefocus.com/the-human-body/one-meal-a-day-diet-omad">Rishi Sunak</a> and singer <a href="https://theconversation.com/one-meal-a-day-diet-popular-with-celebrities-could-do-more-harm-than-good-heres-why-203086">Bruce Springsteen</a> have in common?</p> <p>They’re among an ever-growing group of public figures touting the benefits of eating just one meal a day.</p> <p>As a result, the one meal a day (OMAD) diet is the latest attention-grabbing weight loss trend. Advocates claim it leads to fast, long-term weight loss success and better health, including delaying the ageing process.</p> <p>Like most weight-loss programs, the OMAD diet makes big and bold promises. Here’s what you need to know about eating one meal a day and what it means for weight loss.</p> <h2>The OMAD diet explained</h2> <p>Essentially, the OMAD diet is a type of intermittent fasting, where you fast for 23 hours and consume all your daily calories in one meal eaten within one hour.</p> <p>The OMAD diet rules are presented as simple and easy to follow:</p> <ol> <li> <p>You can eat whatever you want, provided it fits on a standard dinner plate, with no calorie restrictions or nutritional guidelines to follow.</p> </li> <li> <p>You can drink calorie-free drinks throughout the day (water, black tea and coffee).</p> </li> <li> <p>You must follow a consistent meal schedule, eating your one meal around the same time each day.</p> </li> </ol> <p>Along with creating a calorie deficit, resulting in weight loss, advocates believe the OMAD diet’s extended fasting period <a href="https://www.frontiersin.org/articles/10.3389/fphys.2021.771944/full">leads to physiological changes</a> in the body that promote better health, including boosting your metabolism by triggering a process called ketosis, where your body burns stored fat for energy instead of glucose.</p> <h2>What does the evidence say?</h2> <p>Unfortunately, research into the OMAD diet is limited. Most studies have examined its impact on <a href="https://www.cell.com/cell-metabolism/pdf/S1550-4131(18)30512-6.pdf">animals</a>, and the <a href="https://pubmed.ncbi.nlm.nih.gov/35087416/">primary study</a> with humans involved 11 lean, young people following the OMAD diet for a mere 11 days.</p> <p>Claims about the OMAD diet typically rely on research into intermittent fasting, rather than on the OMAD diet itself. There is <a href="https://www.cfp.ca/content/66/2/117.short">evidence</a> backing the efficacy of intermittent fasting to achieve weight loss. However, <a href="https://www.nature.com/articles/s41574-022-00638-x">most studies</a> have focused on short-term results only, typically considering the results achieved across 12 weeks or less.</p> <p>One <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">longer-term study from 2022</a> randomly assigned 139 patients with obesity to either a calorie-restricted diet with time-restricted eating between 8am and 4pm daily, or to a diet with daily calorie restriction alone for 12 months.</p> <p>After 12 months, both groups had lost around the same weight and experienced similar changes in body fat, blood sugar, cholesterol and blood pressure. This indicates long-term weight loss achieved with intermittent fasting is not superior and on a par with that achieved by traditional dieting approaches (daily calorie restriction).</p> <h2>So what are the problems with the OMAD diet?</h2> <p><strong>1. It can cause nutritional deficiencies and health issues.</strong></p> <p>The OMAD diet’s lack of nutritional guidance on what to eat for that one meal a day raises many red flags.</p> <p>The meals we eat every day should include a source of protein balanced with wholegrain carbs, vegetables, fruits, protein and good fats to support <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071223/">optimum health, disease prevention and weight management</a>.</p> <p>Not eating a balanced diet will result in nutritional deficiencies that can result in poor immune function, fatigue and a decrease in bone density, leading to osteoporosis.</p> <p>Fasting for 23 hours a day is also likely to lead to extreme feelings of hunger and uncontrollable cravings, which may mean you consistently eat foods that are not good for you when it’s time to eat.</p> <p><strong>2. It’s unlikely to be sustainable.</strong></p> <p>You might be able to stick with the OMAD diet initially, but it will wear thin over time.</p> <p>Extreme diets – especially ones prescribing extended periods of fasting – aren’t enjoyable, leading to feelings of deprivation and social isolation during meal times. It’s hard enough to refuse a piece of office birthday cake at the best of times, imagine how this would feel when you haven’t eaten for 23 hours!</p> <p>Restrictive eating can also lead to an unhealthy relationship with food, making it even harder to achieve and maintain a healthy weight.</p> <p><strong>3. Quick fixes don’t work.</strong></p> <p>Like other popular intermittent fasting methods, the OMAD diet appeals because it’s easy to digest, and the results appear fast.</p> <p>But the OMAD diet is just another fancy way of cutting calories to achieve a quick drop on the scales.</p> <p>As your weight falls, things will quickly go downhill when your <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">body activates its defence mechanisms</a> to defend your weight loss. In fact, it will regain weight – a response that stems from our hunter-gatherer ancestors’ need to survive periods of deprivation when food was scarce.</p> <h2>The bottom line</h2> <p>Despite the hype, the OMAD diet is unsustainable, and it doesn’t result in better weight-loss outcomes than its predecessors. Our old habits creep back in and we find ourselves fighting a cascade of physiological changes to ensure we regain the weight we lost.</p> <p>Successfully losing weight long-term comes down to:</p> <ul> <li> <p>losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight</p> </li> <li> <p>making gradual changes to your lifestyle to ensure you form habits that last a lifetime.</p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, Charles Perkins Centre Research Program Leader, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

104-year-old woman becomes world's oldest skydiver

<p>A 104-year-old Chicago woman is believed to be the oldest person in the world to tandem skydive, after jumping off a plane from 13,500 feet (4,100 meters) in northern Illinois. </p> <p>On Sunday the 1st of October, Dorothy Hoffner left her walker behind without hesitation and hopped on a Skyvan to set a world record.</p> <p>The 104-year-old could not contain her excitement as she sat on the plane.</p> <p>“Let’s go, let’s go, Geronimo!” she said. </p> <p>Hoffner first started skydiving when she was 100, and initially had to be pushed out of the aircraft, but this time around, things were different. </p> <p>The centenarian insisted on leading the jump while tethered to a U.S. Parachute Association-certified instructor. She was cool and confident as the plane doors opened to reveal the golden crop fields below. </p> <p>Hoffner fearlessly tumbled out of the plane head first and successfully did a forward roll before freefalling from 13,500 feet in the air. </p> <p>The dive lasted seven minutes, including the parachutes slow descent on to the ground. </p> <p>As soon as she landed at Skydive Chicago in Ottawa, just 140 km southwest of Chicago, friends rushed in to share their congratulations. </p> <p>When asked how it felt to be back on land she simply replied with: “Wonderful." </p> <p>“But it was wonderful up there. The whole thing was delightful, wonderful, couldn’t have been better."</p> <p><iframe title="YouTube video player" src="https://www.youtube.com/embed/rQQyc9kRfio?si=3uj4x5hTPyyU6HrJ" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p> <p>Moments after her touchdown, the centenarian told the cheering crowd: “Age is just a number." </p> <p>The previous Guinness World Record for oldest skydiver was set in May 2022 by 103-year-old Swedish woman Linnéa Ingegärd Larsson. </p> <p>Skydive Chicago is currently working with Guinness World Records to certify Hoffner's jump as a record according to <em>WLS-TV</em>. </p> <p>Hoffner's final message for those who haven't tried it: “Skydiving is a wonderful experience, and it’s nothing to be afraid of.

What does having a ‘good relationship with food’ mean? 4 ways to know if you’ve got one

<p><em><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> and <a href="https://theconversation.com/profiles/tracy-burrows-172931">Tracy Burrows</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p>Travelling on a train recently you couldn’t help but overhear two women deep in conversation about a mutual obsession with food, including emotional triggers that pushed them towards chocolate and pizza.</p> <p>They shared feeling guilty about a perceived lack of willpower around food and regularly rummaging through the fridge looking for tasty treats to help soothe emotions. Both lamented not being able to stop and think before eating.</p> <p>Their discussion was a long way from talking about physiological requirements for food to fuel your body and meet essential nutrient needs. Instead, it was highly emotive.</p> <p>It got me thinking about the meaning of a healthy relationship with food, how a person’s eating behaviours develop, and how a “good” relationship can be nurtured. Here’s what a “healthy” food relationship can look like.</p> <h2>What does a ‘good relationship with food’ mean?</h2> <p>You can check whether your relationship with food is “<a href="https://www.rwapsych.com.au/blog/what-does-a-healthy-relationship-with-food-and-eating-look-like/">healthy</a>” by seeing how many items on this list you tick “yes” to. Are you:</p> <ol> <li> <p>in tune with your body cues, meaning you’re aware when you are hungry, when you’re not, and when you’re feeling full?</p> </li> <li> <p>eating appropriate amounts and variety of foods across all food groups, at regular intervals so your nutrient, health and wellbeing needs are met?</p> </li> <li> <p>comfortable eating with others and also eating alone?</p> </li> <li> <p>able to enjoy food, without feelings of guilt or it dominating your life?</p> </li> </ol> <p>If you didn’t get many ticks, you might need to work on improving your relationship with food.</p> <h2>Why does a good relationship with food matter?</h2> <p>A lot of “no” responses indicate you may be using food as a coping mechanism in response to <a href="https://pubmed.ncbi.nlm.nih.gov/36863205/">negative emotions</a>. The problem is this <a href="https://pubmed.ncbi.nlm.nih.gov/36839185/">triggers the brain’s reward centre</a>, meaning although you feel better, this behaviour becomes reinforced, so you are more likely to keep eating in response to negative emotions.</p> <p>Emotional eating and bouts of uncontrolled eating are more likely to be associated with <a href="https://pubmed.ncbi.nlm.nih.gov/36863205">eating disorder symptoms</a> and with having a worse quality diet, including lower intakes of vegetable and higher intakes of nutrient-poor foods.</p> <p>A review of studies on food addiction and mental health found healthy dietary patterns were associated with a lower risk of both disordered eating and <a href="https://pubmed.ncbi.nlm.nih.gov/29368800/">food addiction</a>. Higher intakes of vegetables and fruit were found to be associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35586735/">lower perceived stress</a>, tension, worry and lack of joy in a cohort of more than 8,000 Australian adults.</p> <h2>How to develop a healthy food relationship</h2> <p>There are ways to improve your relationship with food. Here are some tips:</p> <p><strong>1. keep a ‘food mood’ <a href="https://nomoneynotime.com.au/ebooks-meal-plans-more/nmnt-food-and-mood-diary">diary</a>.</strong> Writing down when and where you eat and drink, whom you’re with, what you’re doing, and how all this makes you feel, will give you personal insights into when, what and why you consume the things you do. This helps increase awareness of emotions including stress, anxiety, depression, and factors that influence eating and drinking.</p> <p><strong>2. reflect on what you wrote</strong> in your food mood diary, especially “why” you’re eating when you eat. If reasons include stress, low mood or other emotions, create a distraction list featuring activities such as going for a walk or listening to music, and put it on the fridge, noticeboard or in your phone, so it’s easy to access.</p> <p><strong>3. practise <a href="https://pubmed.ncbi.nlm.nih.gov/28848310/">mindful eating</a>.</strong> This means slowing down so you become very aware of what is happening in your body and mind, moment by moment, when eating and drinking, without making any judgement about your thoughts and feelings. Mindless eating occurs when you eat without thinking at all. Being <a href="https://www.headspace.com/mindfulness/mindful-eating">mindful</a> means taking the time to check whether you really are hungry, or whether it’s “eye” hunger <a href="https://theconversation.com/health-check-six-tips-for-losing-weight-without-fad-diets-52496">triggered by seeing food</a>, “nose” hunger triggered by smells wafting from shops or cafes, “emotional hunger” triggered by feelings, or true, tummy-rumbling hunger.</p> <p><strong>4. learn about <a href="https://nomoneynotime.com.au/hacks-myths-faqs/healthy-eating-why-caring-about-the-foods-you-eat-is-worth-it">your nutrient needs</a>.</strong> Learning why your body needs specific vitamins and minerals and the foods they’re in, rather than just mentally coding food as “good” or “bad”, can help you drop the guilt. Banning “bad” foods makes you want them more, and like them more. Mindfulness can help you gain an <a href="https://pubmed.ncbi.nlm.nih.gov/24035461/">appreciation of foods that are both</a> pleasing and nourishing.</p> <p><strong>5. focus on getting enjoyment from food.</strong> Mindless eating can be reduced by focusing on enjoying food and the pleasure that comes from preparing and sharing food with others. One <a href="https://pubmed.ncbi.nlm.nih.gov/24035461/">intervention</a> for women who had concerns about dieting and weight control used workshops to raise their awareness of food cues that prompt eating, including emotions, or being in places they normally associate with eating, and also sensory aspects of food including taste, touch, smell, sound and texture. It also aimed to instruct them in how to embrace pleasure from social, emotional and cultural aspects of food. The intervention led to a reduction in overeating in response to emotional cues such as sadness and stress. Another <a href="https://pubmed.ncbi.nlm.nih.gov/33347469/">review</a> of 11 intervention studies that promoted eating pleasure and enjoyment found promising results on healthy eating, including better diet quality, healthier portion sizes, healthier food choices and greater liking of healthy foods. Participants also reported healthy food tasted better and got easier to cook more often at home.</p> <h2>Where to get help to improve your relationship with food</h2> <p>A healthy relationship with food also means the absence of <a href="https://www.healthdirect.gov.au/eating-disorders">disordered eating</a>, including binge eating, bulimia and anorexia.</p> <p>If you, or someone you know, shows <a href="https://www.rwapsych.com.au/blog/what-does-a-healthy-relationship-with-food-and-eating-look-like/">signs suggesting disordered eating</a>, such as regularly using restrictive practices to limit food intake, skipping meals, food rituals dictating which foods or combinations to eat at specific times, binge eating, feeling out of control around food, secret eating, inducing vomiting, or use of diet pills, follow up with a GP or health professional.</p> <p>You can get more information from <a href="https://insideoutinstitute.org.au/about-us">InsideOut</a>, an Australian institute for eating disorders.

Why a holiday is good for you – even before you take time off

<p><em><a href="https://theconversation.com/profiles/juan-perez-fernandez-1254221">Juan Pérez Fernández</a>, <a href="https://theconversation.com/institutions/universidade-de-vigo-3910">Universidade de Vigo</a> and <a href="https://theconversation.com/profiles/roberto-de-la-torre-martinez-1257409">Roberto de la Torre Martínez</a>, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em></p> <p>You have spent the past few days on a cloud over your forthcoming, well-deserved holidays, and will go back to daydreaming about them as soon as you finish this article. And the truth is that the benefits of a good holiday can be felt even before the trip begins. Scientific studies show that merely looking forward to a future reward can be <a href="https://advances.sciencemag.org/content/6/25/eaba3828">even more rewarding</a> than the reward itself. This is so thanks to a small molecule called dopamine, which we will talk about later.</p> <p>But, before we continue, let’s think about a few questions. Are holidays really necessary? Why do we need them? And, above all, what are the benefits of a few idle days?</p> <h2>Rest increases cognitive flexibility</h2> <p>Although this may seem unbelievable, there is very little scientific literature that explores the direct benefits of holidays on our brain. What does seem indisputable is that they are essential. This was concluded by <a href="https://www.sciencedirect.com/science/article/abs/pii/S0261517714000685">a 2016 study</a> in which 46 workers from a Dutch company participated.</p> <p>The workers were asked to undergo a test in which they were given objects (for example, a hammer) and asked for the greatest number of uses for their objects in the shortest possible time (construction tool, weapon, paperweight, etc.). What the researchers observed is that, after two or three weeks of vacation, workers had greater cognitive flexibility. Or, to put it another way, they were able to think of a greater number of uses for the objects compared to the results obtained a couple of weeks before the holidays.</p> <p>Most studies concur that, from a biological point of view, one of the main reasons for this increase in cognitive flexibility –and for the benefits of holidays in general– is <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/smi.1434">stress reduction</a>.</p> <p>We will all agree that work generates stress. But we have to make a small distinction here: stress in and of itself does not have to be bad. When it is sporadic, <a href="https://medlineplus.gov/spanish/ency/article/003211.htm">it is usually even beneficial</a> because it activates mechanisms that help us carry out the daily actions of our work, such as meeting a deadline (the authors of this article are working on that right now).</p> <p>The “other stress” – the one that has negative connotations for everyone – is chronic stress. It occurs when it is prolonged over time, either because we are under constant pressure or due to situations that we cannot handle. It generates fatigue, higher levels of anxiety, irritability, and anger. And yes, it’s definitely bad.</p> <h2>Recipe for a holiday that recharges your batteries</h2> <p>The main thing that a good vacation can do for our mental health is precisely to reduce chronic stress levels. When we are idle, our brain is able to reverse – at least temporarily – the negative effects of being under stress. And here comes the key: for holidays to be truly effective, we have to ensure that they really free us from the stress of our work. That is, we must avoid continuing with pending tasks, answering emails, etc.</p> <p>On the other hand, it is essential to prevent our holidays from creating new stressful situations for us.</p> <p>Another key is to enjoy the wait. Why is it that the mere act of waiting for our holidays makes us happy? We mentioned <a href="https://en.wikipedia.org/wiki/Dopamine">dopamine</a> a few paragraphs ago, which is produced in the neurons of two brain regions known as the <a href="https://en.wikipedia.org/wiki/Substantia_nigra">substantia nigra</a> (because of its dark colour under the microscope) and the <a href="https://en.wikipedia.org/wiki/Ventral_tegmental_area">ventral tegmental area</a> (located in the centre of our brain, more or less behind the ears).</p> <p>Both regions, which are home to between 400,000 and 600,000 neurons in humans, send axons to numerous areas of the brain. Through the release of dopamine, they play a key role in the pleasant feelings brought on by new experiences and rewards. Therefore, knowing that our holidays are coming increases the dopamine levels in our brain and gives us that feeling of pleasure.</p> <p>Similarly, the best holidays are those in which we enjoy new experiences (such as exploring different places) and rewards (like that seafood platter we have been waiting for all year). Of course, what one finds rewarding is entirely subjective, and what is pleasant for one person can cause stress for others.</p> <h2>To enjoy or not to enjoy</h2> <p>This system that generates pleasure is also affected during chronic stress. <a href="https://www.nature.com/articles/s12276-020-00532-4">Science shows</a> that high or chronic levels of stress, such as those we are subjected to throughout the year during our workday, are capable of causing a reduction in the amount of dopamine released and/or changes in how it is metabolised.</p> <p>The worst thing is that the changes do not only occur in the substantia nigra or in the ventral tegmental area. <a href="https://www.nature.com/articles/s12276-020-00532-4">It has been found</a> that chronic stress is even capable of changing the number of dopamine receptors in the areas that receive these projections. When this occurs, depressive behaviours often develop. Therefore, a vacation that frees us from stress will help to rebalance the dopaminergic system.</p> <p>What is still not entirely clear is whether taking holidays for a long period provides better effects than taking them in a staggered way and in shorter periods.</p> <p>Be that as it may, good holidays are good for us.

What makes a good life? Existentialists believed we should embrace freedom and authenticity

<p><em><a href="https://theconversation.com/profiles/oscar-davis-876589">Oscar Davis</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>How do we live good, fulfilling lives?</p> <p>Aristotle first took on this question in his <a href="https://plato.stanford.edu/entries/aristotle-ethics/">Nicomachean Ethics</a> – arguably the first time anyone in Western intellectual history had focused on the subject as a standalone question.</p> <p>He formulated a teleological response to the question of how we ought to live. Aristotle proposed, in other words, an answer grounded in an investigation of our purpose or ends (<em>telos</em>) as a species.</p> <p>Our purpose, he argued, can be uncovered through a study of our essence – the fundamental features of what it means to be human.</p> <h2>Ends and essences</h2> <p>“Every skill and every inquiry, and similarly every action and rational choice, is thought to aim at some good;” Aristotle states, “and so the good has been aptly described as that at which everything aims.”</p> <p>To understand what is good, and therefore what one must do to achieve the good, we must first understand what kinds of things we are. This will allow us to determine what a good or a bad function actually is.</p> <p>For Aristotle, this is a generally applicable truth. Take a knife, for example. We must first understand what a knife is in order to determine what would constitute its proper function. The essence of a knife is that it cuts; that is its purpose. We can thus make the claim that a blunt knife is a bad knife – if it does not cut well, it is failing in an important sense to properly fulfil its function. This is how essence relates to function, and how fulfilling that function entails a kind of goodness for the thing in question.</p> <p>Of course, determining the function of a knife or a hammer is much easier than determining the function of <em>Homo sapiens</em>, and therefore what good, fulfilling lives might involve for us as a species.</p> <p>Aristotle argues that our function must be more than growth, nutrition and reproduction, as plants are also capable of this. Our function must also be more than perception, as non-human animals are capable of this. He thus proposes that our essence – what makes us unique – is that humans are capable of reasoning.</p> <p>What a good, flourishing human life involves, therefore, is “some kind of practical life of that part that has reason”. This is the starting point of Aristotle’s ethics.</p> <p>We must learn to reason well and develop practical wisdom and, in applying this reason to our decisions and judgements, we must learn to find the right balance between the excess and deficiency of virtue.</p> <p>It is only by living a life of “virtuous activity in accordance with reason”, a life in which we flourish and fulfil the functions that flow from a deep understanding of and appreciation for what defines us, that we can achieve <em>eudaimonia</em> – the highest human good.</p> <h2>Existence precedes essence</h2> <p>Aristotle’s answer was so influential that it shaped the development of Western values for millennia. Thanks to philosophers and theologians such as <a href="https://www.britannica.com/biography/Saint-Thomas-Aquinas">Thomas Aquinas</a>, his enduring influence can be traced through the medieval period to the Renaissance and on to the Enlightenment.</p> <p>During the Enlightenment, the dominant philosophical and religious traditions, which included Aristotle’s work, were reexamined in light of new Western principles of thought.</p> <p>Beginning in the 18th century, the Enlightenment era saw the birth of modern science, and with it the adoption of the principle <em>nullius in verba</em> – literally, “take nobody’s word for it” – which became the motto of the <a href="https://royalsociety.org/about-us/history/">Royal Society</a>. There was a corresponding proliferation of secular approaches to understanding the nature of reality and, by extension, the way we ought to live our lives.</p> <p>One of the most influential of these secular philosophies was existentialism. In the 20th century, <a href="https://www.britannica.com/biography/Jean-Paul-Sartre">Jean-Paul Sartre</a>, a key figure in existentialism, took up the challenge of thinking about the meaning of life without recourse to theology. Sartre argued that Aristotle, and those who followed in Aristotle’s footsteps, had it all back-to-front.</p> <figure class="align-right zoomable"><figcaption></figcaption></figure> <p>Existentialists see us as going about our lives making seemingly endless choices. We choose what we wear, what we say, what careers we follow, what we believe. All of these choices make up who we are. Sartre summed up this principle in the formula “existence precedes essence”.</p> <p>The existentialists teach us that we are completely free to invent ourselves, and therefore completely responsible for the identities we choose to adopt. “The first effect of existentialism,” Sartre wrote in his 1946 essay <a href="https://www.marxists.org/reference/archive/sartre/works/exist/sartre.htm">Existentialism is a Humanism</a>, “is that it puts every man in possession of himself as he is, and places the entire responsibility for his existence squarely upon his own shoulders.”</p> <p>Crucial to living an authentic life, the existentialists would say, is recognising that we desire freedom above everything else. They maintain we ought never to deny the fact we are fundamentally free. But they also acknowledge we have so much choice about what we can be and what we can do that it is a source of anguish. This anguish is a felt sense of our profound responsibility.</p> <p>The existentialists shed light on an important phenomenon: we all convince ourselves, at some point and to some extent, that we are “bound by external circumstances” in order to escape the anguish of our inescapable freedom. Believing we possess a predefined essence is one such external circumstance.</p> <p>But the existentialists provide a range of other psychologically revealing examples. Sartre tells a story of watching a waiter in a cafe in Paris. He observes that the waiter moves a little too precisely, a little too quickly, and seems a little too eager to impress. Sartre believes the waiter’s exaggeration of waiter-hood is an act – that the waiter is deceiving himself into being a waiter.</p> <p>In doing so, argues Sartre, the waiter denies his authentic self. He has opted instead to assume the identity of something other than a free and autonomous being. His act reveals he is denying his own freedom, and ultimately his own humanity. Sartre calls this condition “bad faith”.</p> <h2>An authentic life</h2> <p>Contrary to Aristotle’s conception of <em>eudaimonia</em>, the existentialists regard acting authentically as the highest good. This means never acting in such a way that denies we are free. When we make a choice, that choice must be fully ours. We have no essence; we are nothing but what we make for ourselves.</p> <p>One day, Sartre was visited by a pupil, who sought his advice about whether he should join the French forces and avenge his brother’s death, or stay at home and provide vital support for his mother. Sartre believed the history of moral philosophy was of no help in this situation. “You are free, therefore choose,” he replied to the pupil – “that is to say, invent”. The only choice the pupil could make was one that was authentically his own.</p> <p>We all have feelings and questions about the meaning and purpose of our lives, and it is not as simple as picking a side between the Aristotelians, the existentialists, or any of the other moral traditions. In his essay, <a href="https://www.gutenberg.org/files/3600/3600-h/3600-h.htm#link2HCH0019">That to Study Philosophy is to Learn to Die</a> (1580), Michel de Montaigne finds what is perhaps an ideal middle ground. He proposes “the premeditation of death is the premeditation of liberty” and that “he who has learnt to die has forgot what it is to be a slave”.</p> <p>In his typical style of jest, Montaigne concludes: “I want death to take me planting cabbages, but without any careful thought of him, and much less of my garden’s not being finished.”</p> <p>Perhaps Aristotle and the existentialists could agree that it is just in thinking about these matters – purposes, freedom, authenticity, mortality – that we overcome the silence of never understanding ourselves. To study philosophy is, in this sense, to learn how to live.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/204364/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/oscar-davis-876589">Oscar Davis</a>, Indigenous Fellow - Assistant Professor in Philosophy and History, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What to eat before bed if you want a good night’s sleep

<p><strong>What to eat before bed</strong></p> <p>It’s after 8 pm and you can feel your stomach grumbling. Should you stick it out until morning or head to the kitchen? Night-time eating tends to get a bad reputation – people often worry it causes weight gain, heartburn, indigestion or all three. But it all depends on what you reach for, says nutritionist Nishta Saxena.</p> <p>Saxena says there isn’t a clear-cut time of day that we have to stop eating. Studies have found that it’s not when you’re eating, but how much and what you’re eating which matters. Super salty snacks at the end of the day can, for example, make you dehydrated and interrupt your sleep – and they’re not the only culprits that can affect whether you have a good night’s rest.</p> <p>In general, it’s best to eat small portions before bed. Also try to stay away from foods high in protein or fat, which can be harder for our bodies to digest and can interrupt the natural cadence of our systems, which slow down for the night by producing sleep-inducing hormones like melatonin. Excessive sugar can also act like a stimulant – a bad choice if you’re trying to catch some Zzzs.</p> <p>Saxena suggests eating something that’s high in carbohydrates, which can promote sleep and help you to relax. This is because carbs don’t require as much blood flow or work from your body to digest and are therefore unlikely to interrupt your sleep. If you find yourself with an after-dinner case of the munchies, follow these tips on what to eat before bed.</p> <p><strong>Kiwis</strong></p> <p>Kiwis can help to promote sleep because they are rich in serotonin and antioxidants (such as Vitamins C and E). Serotonin helps to make you feel relaxed and certain antioxidants have sleep-promoting qualities. </p> <p>Plus, these fuzzy fruits are extremely high in vitamin C and our bodies can digest them quickly, says Saxena. They also support heart and digestive health as well as natural immunity.</p> <p><strong>Tart cherries</strong></p> <p>Tart cherries and tart cherry juice contain concentrated amounts of melatonin, a hormone that helps your body regulate sleep-wake cycles, says Saxena. Studies show that they can help to reduce insomnia, plus they also contain other sleep-inducing agents like tryptophan (a precursor of serotonin). </p> <p>Since tart cherries can be a little bit harder to find than other fruits, Saxena suggests keeping some in your freezer and using them to make a smoothie.</p> <p><strong>Nuts</strong></p> <p>Nuts are great for a variety of health benefits, says Saxena, and they’re also a good late-night snack. Just don’t dish out a whole cup of nuts, she warns, because they do contain surprising amounts of protein and fat. </p> <p>In particular, she recommends walnuts and almonds – they contain natural melatonin as well as magnesium, which has the potential to reduce insomnia in adults.</p> <p><strong>Popcorn</strong></p> <p>While pre-packaged microwave popcorn most likely contains too much salt to be a good bedtime snack, popping your own can satisfy people who are craving snack foods like chips. </p> <p>Popcorn is also relatively filling – just don’t drown your bowl in butter and salt.</p> <p><strong>Yoghurt</strong></p> <p>Dairy products, while not consumed by everyone, have a lot of components that stimulate sleep, says Saxena. Something like yoghurt doesn’t require a lot of digestive processes, and even full fat yoghurt doesn’t have a ton of fat in it, making it easy to digest. </p> <p>Plus, it’s filled with amino acids, like tryptophan, which promote sleep.</p> <p><strong>Green bananas</strong></p> <p>Saxena says a greenish banana, “almost the colour of a tulip stem,” is a great evening snack. At this point, the banana is full of starch, which means it hasn’t yet become sugar, and this can be great for our gut bacteria and also helps to promote sleep. </p> <p>She adds that the banana should be firm and have a tiny bit of yellow in the midsection. If it has black spots, it’s too ripe to help with sleep and won’t provide a benefit.</p> <p><strong>Warm milk</strong></p> <p>The benefits of warm milk for sleep are well-documented, says Saxena. This is in part because milk contains tryptophan, an amino acid that promotes sleep. Warm fluids in general can relax our digestive muscles. </p> <p>“It can be a self-care moment when you’re having something warm,” Saxena says. “Your hands are wrapped around the mug and it’s a sensory experience.”</p> <p><strong>Cottage cheese</strong></p> <p>While cottage cheese has lots of protein, it also has the benefits of dairy, including amino acids, that help to promote sleep. It’s also nutrient-dense, containing calcium, magnesium, iron, and phosphorus, which are essential for bodily function. </p> <p>It can also be a good late-night snack for athletes, because it’s high in the protein casein, which helps to reduce muscle breakdown overnight. Still, stay away from other cheeses before bed – most are very high in fat and easy to overeat, warns Saxena.</p> <p><strong>Oatmeal</strong> </p> <p>While people often think of oatmeal as a breakfast food, oats are high in melatonin and so can make a good bedtime snack. Like dairy products, oats also contain the amino acid tryptophan. </p> <p>You can also spice up your oatmeal with many of the other foods that are okay to eat before bed – tart cherries, yogurt, or almond butter, for example.</p> <p><strong>Pasta</strong></p> <p>If you’re really hungry, try some pasta – but keep the portion small and be careful to not load your dish with toppings that are high in protein or fat. </p> <p>For example, you don’t want to have a super-cheesy meatball pasta before bed, says Saxena. But a small serving of plain pasta with pesto sauce might do the trick.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/sleep/what-to-eat-before-bed-if-you-want-a-good-nights-sleep?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Tony Bennett: the timeless visionary who, with a nod to America’s musical heritage, embraced the future

<p><em><a href="https://theconversation.com/profiles/jose-valentino-ruiz-1293457">Jose Valentino Ruiz</a>, <a href="https://theconversation.com/institutions/university-of-florida-1392">University of Florida</a></em></p> <p>In the history of American popular music, there have been few luminaries as enduring and innovative as Tony Bennett.</p> <p>With a career that spanned almost 80 years, Bennett’s smooth tones, unique phrasing and visionary musical collaborations left an indelible mark on vocal jazz and the recording industry as a whole.</p> <p>That his <a href="https://apnews.com/article/tony-bennett-dies-c3b3a7e2360449fb936a38794c7c3266">death at the age of 96</a> on July 21, 2023, was mourned by artists as varied as <a href="https://twitter.com/KeithUrban/status/1682395658395824133">Keith Urban</a>, <a href="https://twitter.com/OzzyOsbourne/status/1682411338340126720">Ozzy Osbourne</a> and <a href="https://twitter.com/HarryConnickJR?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1682411086656557056%7Ctwgr%5E04a78435a793b5246d7bc19e09529f2b2f0bcfab%7Ctwcon%5Es1_&amp;ref_url=https%3A%2F%2Fvariety.com%2F2023%2Fmusic%2Fnews%2Ftony-bennett-elton-john-reaction-tribute-1235676405%2F">Harry Connick Jr.</a> should come as no surprise. Yes, Bennett was a jazz crooner. But if his voice was always a constant – even late into his 80s, way past an age when most other singers have seen their vocal abilities diminish – then his embrace of the contemporary was every bit a facet of Bennett’s appeal.</p> <h2>Vocal innovator</h2> <p>Bennett’s journey is a testament to the power of daring innovation.</p> <p>From the early days of his career in the 1950s to his final recordings in the early 2020s, he fearlessly explored new musical territories, revolutionizing vocal jazz and captivating audiences across generations.</p> <p>His vocal style and phrasing were distinctive and set him apart from other artists of his time. He utilized a delayed or “laid-back” approach to falling on the note, a technique known as “<a href="https://www.musictheoryacademy.com/how-to-read-sheet-music/rubato/">rubato</a>.” This created a sense of anticipation in his phrasing, adding an element of surprise to his performances. Through Bennett’s skilled use of rubato, he was able to play with the tempo and rhythm of a song, bending and stretching musical phrases to evoke a range of emotions. This subtle manipulation of timing gave his songs a natural and conversational quality, making listeners feel as though he was intimately sharing his stories with them.</p> <p>Armed with this silky, playful voice, Bennett found fame fairly early on in his career, delivering jazz standards alongside the likes of Mel Tormé and Nat King Cole. By the mid-1960s, he was being touted by Frank Sinatra as “the best singer in the business.”</p> <p>But his musical style fell out of fashion in the 1970s – a lean period during which Bennett <a href="https://www.washingtonpost.com/history/2023/07/21/tony-bennett-son-life-career-drugs/">almost succumbed to a drug overdose</a>. Then, in the 1990s, Bennett found a new audience and set off a series of collaborations with contemporary musical stars that would become the standard for his later career.</p> <p>No genre of artistry was deemed off-limits for Bennett. “<a href="https://www.tonybennett.com/music-detail.php?id=11">Duets: An American Classic</a>,” released to coincide with his 80th birthday in 2006, saw collaborations with country stars such as k.d. lang and the Dixie Chicks – now known as the Chicks – and soul legend Stevie Wonder, alongside kindred jazz spirits such as Diana Krall. “Duets II,” a 2011 follow-up, saw further explorations with the likes of Aretha Franklin, Queen Latifah, Willie Nelson and Amy Winehouse, in what would become the <a href="https://faroutmagazine.co.uk/amy-winehouse-final-recording-session/">British singer’s last recording</a>.</p> <p>But his cross-generational, cross-genre and cross-cultural appeal is perhaps best exemplified by his <a href="https://www.nytimes.com/2023/07/21/arts/music/tony-bennett-lady-gaga.html">collaborations with Lady Gaga</a>, first on the 2014 Grammy-winning album “Cheek to Cheek.” The recording brought together two artists from different generations, genres and backgrounds, uniting them in a harmonious celebration of jazz classics. The collaboration not only showcased each one’s vocal prowess, but also sent a powerful message about the unifying nature of music.</p> <p>Lady Gaga, a pop artist with avant-garde leanings, might have seemed an unlikely partner for Bennett, the quintessential jazz crooner. Yet their musical chemistry and mutual admiration resulted in an album that mesmerized audiences worldwide. “Cheek to Cheek” effortlessly transcended musical boundaries, while the duo’s magnetic stage presence and undeniable talent enchanted listeners.</p> <p>The successful fusion of jazz and pop encouraged artists to experiment beyond traditional boundaries, leading to more cross-genre projects across the industry – proving that such projects could go beyond one-off novelties, and be profitable at that.</p> <h2>Timeless artistry</h2> <p>Bennett’s embrace of contemporary artists did not mean that he abandoned his own musical self. By blending traditional jazz with contemporary elements, he managed to captivate audiences across generations, appealing to both longtime fans and new listeners.</p> <p>One key aspect of Bennett’s success was his ability to embody the sentiment of old America, reminiscent of artists like Sinatra, Billie Holiday and Louis Armstrong, while infusing contemporary nuances that resonated with the human condition of a more modern era. His approach to music captured both the essence and struggle of America, giving his songs a timeless and universal appeal. Moreover, his voice conveyed familiarity and comfort, akin to listening to a beloved uncle.</p> <p>Bennett’s albums stood out not only for his soulful voice and impeccable delivery but also for the way he drew others from varied musical backgrounds into his world of jazz sensibilities. As a producer, he recognized the importance of nurturing creativity and bringing out the best in artists.</p> <p>Meanwhile, Bennett’s approach to evolving his own sound while preserving its essence sets him apart as an artist. Fearless in his pursuit of innovation, he delved into contemporary musical elements and collaborated with producers to infuse new sonic dimensions into his later albums. The result drew listeners into an <a href="https://www.youtube.com/watch?v=6kNpdLZwetU">intimate and immersive, concert-like acoustic journey</a>.</p> <h2>Depth of emotion</h2> <p>The greats in music have an ability to speak to the human experience. And either in collaboration with others or on his own, Bennett was able to achieve this time and time again.</p> <p>His albums were successful not only due to their technical brilliance and musicality but also because Bennett’s voice conveyed a depth of emotion that transcended barriers of time and culture, touching the hearts of listeners from various backgrounds. There was a universality in his music that made him a beloved and revered artist across the globe.</p> <p>Bennett’s life spanned decades of societal upheavals in the United States. But in his music, listeners could always find beauty in challenging times. And as the 20th- and 21st-century American music industry went through its own revolutions, Bennett’s artistic evolution mirrored the changes, cementing his place as a music icon who defies the boundaries of time and trends.<!-- Below is The Conversation's page counter tag.

Good news for weekend warriors: people who do much of their exercise on a couple of days still get heart benefits

<p><em><a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/raaj-kishore-biswas-1374060">Raaj Kishore Biswas</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Physical activity has <a href="https://bjsm.bmj.com/content/54/24/1451">established benefits</a> for health. The <a href="https://bjsm.bmj.com/content/54/24/1451">World Health Organization</a> recommends adults do a minimum of 150–300 minutes of moderate or 75–150 minutes of vigorous activity each week. This can include active transport from place-to-place, exercise for fun and fitness, energetic housework or physical activity at work.</p> <p>These amounts can be accrued by being, as the <a href="https://bjsm.bmj.com/content/54/24/1451">WHO recommends</a>, regularly active throughout the week, or being a “weekend warrior” who does the bulk of their activity on one to two days only, which don’t need to be consecutive.</p> <p>So far, experts haven’t fully established which of the two patterns is better for overall health. For many people, busy lifestyles may make it hard to be physically active every day. It may be more feasible to squeeze most physical activity and exercise into a few days.</p> <p>Fresh <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">analysis</a> of the large <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a> database attempted to compare these two patterns of weekly activity and compare how they reduced cardiovascular risk for heart attacks, heart failure, irregular heart beat and stroke.</p> <h2>What the new study found</h2> <p>Researchers analysed records from 89,573 participants who wore a wrist activity tracker for seven days and were tracked for cardiovascular events for over six years.</p> <p>Those who did less than the WHO recommended 150 minutes of moderate-to-vigorous physical activity per week were considered inactive. About a third (33.7%) of participants were inactive. Some 42.2% were termed active “weekend warriors” (they did at least 150 minutes and more than half of it occurred within one to two days) and 24% were regularly active (at least 150 minutes with most activity spread out over three or more days).</p> <p>Researchers considered the potential factors that could explain the link between physical activity and new cases of cardiovascular events, such as smoking and alcohol intake. They found both active groups showed similarly lower risk of heart attack (a 27% reduction for weekend warriors and 35% for regularly active people, compared with inactive participants).</p> <p>For heart failure, weekend warriors had a 38% lower risk than inactive people, while regular exercisers had a 36% lower risk. Irregular heartbeat risk was 22% lower for weekend warriors and 19% lower for regularly actively people. Stroke was 21% and 17% lower for weekend warriors and regular exercisers, respectively.</p> <h2>Not so fast. Some study limitations</h2> <p>Although the information was recorded by activity trackers, researchers did not consider on which days of the week the activity was done. Some people may have been active on Saturdays and Sundays, others might have chosen Wednesday and Friday – or different days each week. In that sense, <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">the study</a> examined a “pseudo-weekend warrior” pattern.</p> <p>Despite the many advantages the UK Biobank activity trackers have over <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">questionnaire-based studies</a>, these trackers are not great at capturing strength-training exercise, such as weights or pilates, and other static activities that have <a href="https://academic.oup.com/aje/article/187/5/1102/4582884">established cardiovascular</a> health benefits.</p> <h2>What other research in this area says</h2> <p>There have been several questionnaire based studies in this area in <a href="https://academic.oup.com/aje/article/160/7/636/136697">the past 20 years</a>.</p> <p>Our <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">2017 study</a>, for example, combined data from 63,591 adults from England and Scotland and tracked them over 12 years. We looked at <a href="https://theconversation.com/weekend-warrior-exercise-is-it-good-for-you-70964">risk reductions</a> for death from any cause, cardiovascular disease and cancer causes. We found similar benefits among people who clocked at least 150 minutes of moderate-intensity physical activity or at least 75 minutes of vigorous-intensity physical activity in one to two sessions per week, compared with three sessions or more per week.</p> <p>Our more <a href="https://www.nature.com/articles/s41591-022-02100-x">recent studies</a> used activity trackers and emphasised the flexibility of activity patterns that benefit the heart and circulation. We found doing short one-minute-long bouts of incidental vigorous physical activity three to four times a day can cut the risk of death from cardiovascular causes by <a href="https://www.nature.com/articles/s41591-022-02100-x">almost half</a>.</p> <p>Similarly, in another study we found just 19 minutes of vigorous physical activity a week was associated with <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">40% reduction</a> in the risk of cardiovascular death, with steadily increasing benefits to the maximum amount of vigorous activity recorded (110 minutes a week linked to a 75% risk reduction).</p> <h2>What it means for you and your routine</h2> <p>Taken together, the <a href="https://jamanetwork.com/journals/jama/fullarticle/2807286">new study</a> and <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">previous research</a> suggest the same thing: if it is difficult to find time to be active during a busy week, it is good enough to plan moderate to vigorous physical activities in a couple of weekdays or in the weekend.</p> <p>That said, there are benefits in being regularly physically active on most days of the week. A good session of aerobic exercise, for example, improves health indicators such as <a href="https://www.ahajournals.org/doi/full/10.1161/HYP.0000000000000196">blood pressure</a>, and <a href="https://link.springer.com/article/10.1007/s40279-021-01473-2">blood glucose</a> and <a href="https://lipidworld.biomedcentral.com/articles/10.1186/s12944-017-0515-5">cholesterol levels</a> for a day or longer. Such effects can moderate some of the long-term health risks of these factors and assist with their day-to-day management.</p> <p>But confirmation that we can be flexible about how physical activity is accumulated across the week for heart health benefits is encouraging. It offers more opportunities for more people to be active when it is convenient and practical for them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/210053/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, Professor of Physical Activity, Lifestyle, and Population Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, Postdoctoral Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/raaj-kishore-biswas-1374060">Raaj Kishore Biswas</a>, Research Fellow &amp; Biostatistician, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s what would happen to your body if you didn’t have your morning coffee

<p><strong>What happens when you skip coffee entirely?</strong></p> <p>Coffee is a morning constant for many, as reliable as the sunrise or the tides. Miss it, and you can feel dazed, confused and even risk a pounding headache. There’s a good reason for that: Caffeine produces some reliable physical changes in your body upon which you can easily become dependent.</p> <p>With that first sip of coffee, caffeine enters your bloodstream and begins making its way to your brain where it blocks an inhibitory neurotransmitter called adenosine, according to the <em>National Academy of Sciences</em>. That, in turn, sets off the release of feel-good hormones like dopamine and serotonin, causing a stimulant effect. Coffee’s so-called half-life – meaning the amount of time it takes for the amount of caffeine in the body to be reduced by 50 per cent – is about five hours on average. </p> <p>That explains why the average energy drink or coffee buzz lasts about that long. But how quickly caffeine leaves your system depends on a number of things, including age, medical conditions, drug interactions and lifestyle habits (like smoking).</p> <p><strong>A shock to the system</strong></p> <p>So, no surprise, when you’re deprived of your morning coffee, you don’t just suffer due to routine alteration. You suffer chemically, too. As anybody who’s kicked their coffee habit will tell you: The side effects can be pretty noticeable and jarring. Some of the more common symptoms of caffeine withdrawal stem from the inherent perks of those multi cups of Joe.</p> <p>Minus the kickstart to your metabolism, you’ll feel tired, sluggish, foggy-headed, and physically delayed, according to a review of studies published in 2020 in <em>StatPearls</em>. Researchers found that the more caffeine you consume, the more severe the withdrawal; but abstinence from even small amounts – we’re talking one cup of coffee per day – also produced symptoms of caffeine withdrawal. They kick in 12 to 24 hours after your last caffeine fix and may last up to nine days, says Dr Sherry A Ross, women’s health expert, author of <em>She-ology: The She-quel. </em></p> <p>“Caffeine is a stimulating drug that some people can easily become addicted to,” she explains. “Depending on the quantity and type of caffeine you are consuming daily, your body type and frequency of consumption can set you up for a caffeine addiction.”</p> <p><strong>Coffee's not all bad</strong></p> <p>Just because you can develop a dependence on your morning jolt doesn’t mean that cup of java belongs on the do-not-consume list. Just the opposite, in fact. A large review of studies published in 2017 in the journal BMJ found that coffee consumption is not only safe for most people (except pregnant women and women who are at an increased risk of fracture), it also provides a number of health benefits, especially for people with chronic liver disease. </p> <p>The review also showed that participants who consistently drank at least three cups of coffee per day had a lower risk of type 2 diabetes, kidney disease, gallstone disease, cancer (including melanoma, leukaemia and prostate, endometrial, oral, and liver cancer), as well as cardiovascular disease, coronary heart disease and stroke as compared with coffee abstainers.</p> <p>The trick, of course, is practicing portion control. The researchers found that the health benefits of coffee top out at three to four cups a day (as compared to none). That echoes the larger caffeine recommendation from the US Food and Drug Administration, which suggests no more than 400 mg of caffeine per day; that’s the amount in about four cups of coffee, 10 cans of cola, or two energy drinks.</p> <p>Image credits: Getty Images</p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/heres-what-would-happen-to-your-body-if-you-didnt-have-your-morning-coffee" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

"Ended for good": Prince William launches project inspired by Lady Di

<p>Prince William has launched his most ambitious project to date, announcing his plan to end homelessness in the UK within five short years. </p> <p>The Prince of Wales set out to visit six areas in the UK that experience different types of homelessness with a distinct set of challenges, outlining a detailed plan to see homelessness eradicated. </p> <p>On his two-day tour, the 41-year-old royal shared that his late mother, Princess Diana, was a big inspiration behind the project, after she helped open William's eyes to the nation-wide problem. </p> <p>In the south London borough of Lambeth, Prince William described how he was inspired by "heart-breaking" visits to shelters he made with his mother as a child. </p> <p>"My first visit to a homelessness shelter was when I was 11 with my mother," he told the Mosaic Clubhouse, which supports people with mental health problems.</p> <p>"The visits we made, left a deep and lasting impression."</p> <p>"I met so many extraordinary people and listened to so many heart-breaking personal stories. Too many people have found themselves without a stable and permanent place to call home."</p> <p>"Through these visits, I have seen first-hand the breadth and complexities of homelessness."</p> <p>William said he hoped the Homewards program would "inspire belief throughout the UK and beyond that homelessness can be ended for good".</p> <p>Prince William's Homewards program focuses on preventing homelessness before it begins, bringing together all organisations working in the sector to create solutions that target local challenges.</p> <p>The launch of the project, which was two years in the making, comes days before what would have been Diana's 62nd birthday on July 1st. </p> <p>A major focus of Homewards will be on providing homes to those who need them.</p> <p>"I am pleased to stand here today at the start of our path to ending homelessness," he said.</p> <p>"Over the next five years, I believe that we have a unique opportunity to develop innovative new solutions and scale tangible impact. This will inspire belief throughout the UK – and beyond – that homelessness can be ended for good."</p> <p><em>Image credits: Getty Images</em></p>
