After the tragic news of Michael Mosley's passing, we are re-releasing our episode with him, originally released in March 2023: If you had to do just one thing to improve your health, what would it be? Our busy lives mean it can be difficult to keep up healthy habits, and with so much conflicting advice out there it’s tricky to separate fact from fiction. In today’s episode, Jonathan is joined by medical doctor, journalist, and presenter Michael Mosley, who is alongside ZOE regular Tim Spector, to discuss Michael’s four key habits to improve our health.  Michael’s latest book ‘Just One Thing’ explores these habits and has seen him speak to singing scientists and eccentric iceman to healthy habit experts and evangelists. And of course, being Michael, he tried every habit out himself. We talk about which methods are the most effective, which he has incorporated into his life, and how he makes his new habits stick. 🌱 Try our new plant based wholefood supplement - Daily 30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system If you want to uncover the right foods for your body, head to zoe.com/podcast and get 10% off your membership.

Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm. As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer. Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center. In today's episode of ZOE Science & Nutrition, Jonathan and Karyn explore the body's internal clocks and ask: why do our muscles have their own schedule, and is there an ideal time of day to exercise? 🌱 Try our new plant based wholefood supplement - Daily 30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system Learn how your body responds to food 👉 zoe.com/podcast for 10% off Timecodes 00:00 Introduction 00:18  Quickfire questions 02:01  Why are muscles important, particularly as we get older? 08:45  Why we all lose strength as we age 11:07  What type of exercise do we need to maintain our muscle strength as we age? 14:55  What is a circadian clock? 19:25  Everything has a circadian rhythm 21:32  Why do our muscles work on a 24-hour cycle? 24:20  Humans are stronger in the afternoon 30:24  Is there a best time to exercise? 35:01  Can exercise before or after work help shift workers with jet lag? 37:33  Is there a difference between men and women’s responses to circadian rhythms?   41:44  What are the effects of time-restricted eating on muscle mass? 53:42  Summary Mentioned in today's episode: Defining the age-dependent and tissue-specific circadian transcriptome in male mice from Cell Reports Related studies:  Timing is everything: Circadian clocks set the rhythm for vital functions in bacteria from the University of Chicago Effects of resveratrol on in vitro circadian clock gene expression in young and older human adipose-derived progenitor cells in Aging Age is associated with dampened circadian patterns of rest and activity: The Study of Muscle, Mobility and Aging (SOMMA) in medRxiv Have feedback or a topic you'd like us to cover?

The carnivore diet, heralded as a panacea by some, faces scrutiny as its proponents claim miraculous health benefits while skeptics question its sustainability and potential risks. Advocates argue for its simplicity and purported improvement in autoimmune conditions and weight loss. However, critics cite concerns about nutritional deficiencies, lack of fiber, and long-term health consequences such as heart disease and cancer. Amidst the debate, sites like https://www.flexmagichealth.com/ provide platforms for both sides to present their arguments, offering research-backed insights and personal anecdotes. As discussions persist, the carnivore diet remains exposed to ongoing examination, revealing both its promises and pitfalls.

Don't make it too complicated. The key is you need to go low carb, once you eat low carb and stop snacking, you'll naturally intermittent fast. Just follow your feelings. Easy.

surprised you didn't do more research before recording this. you don't know what you're talking about at all. I'm not even advocating carnivore but this was hardly a refutation.

it would have been interesting to consider transplant recipients who have to take powerful immunosuppressants to prevent rejection. so due to a (necessary) medical intervention rather than inflammation. Emphatic dietary advice firmly discourages fermented foods. any comment in the light of this fascinating podcast

why would eating meat which was a major component that the human species evolved on be bad for us? doesn't make sense! I'd give the ultra processed seed spreads a miss too rather than reducing butter. not good information given here.
