    The #1 Dementia risk factor nobody talks about, and what to do
    Oct 16 2025
    Get your free 5-step plan for hearing loss diagnosis and treatment: click here Hearing loss affects 1 in 5 people globally, increases the risk of developing dementia, and has no cure. An astonishing half a billion people have hearing loss, which impacts their ability to communicate and connect with others. Hearing loss cases are increasing fast, especially among younger people. For many, hearing aids and cochlear implants can be life-changing, but they can’t help everyone. But there is hope: Scientists around the world have been working tirelessly to develop NEW treatments for hearing loss. In this episode, Jonathan speaks to Dr. Marcelo Rivolta, a professor of sensory stem cell biology at Sheffield University. He’s on the cusp of a major breakthrough that could mean hearing loss becomes a thing of the past. What you’ll learn: Why hearing loss is becoming more common The shocking link between hearing loss and a 500% increased risk of dementia How modern headphones and loud concerts cause permanent, irreversible damage Why hearing loss can be more isolating than blindness The simple ways you can protect your hearing today How current technologies like hearing aids and cochlear implants work About the groundbreaking new science that could cure deafness using stem cells About Marcelo Rivolta Marcelo Rivolta is a Professor of Sensory Stem Cell Biology at the University of Sheffield. For over two decades, his research has focused on the use of human stem cells for the understanding and treatment of hearing loss. His lab was the first to demonstrate that it was possible to create both auditory hair cells and neurons from stem cells, and his pioneering work is now moving towards clinical trials in humans.

  • Lose weight by controlling these hormones | Bariatric surgeon Dr. Andrew Jenkinson

    Lose weight by controlling these hormones | Bariatric surgeon Dr. Andrew Jenkinson
    Oct 9 2025
    🥑 Make smarter food choices. Become a member at http://zoe.com Have you ever wondered why you can lose weight on a diet, only for it to come back with a vengeance? If you’ve blamed yourself for a lack of willpower, our guest today argues you’ve been misled. The old mantra of “eat less, move more” is failing us, and the key to understanding why lies deep within our biology. In this episode, Jonathan is joined by Dr. Andrew Jenkinson, a bariatric surgeon and author with decades of experience in the science of metabolism. Dr. Jenkinson dismantles the calorie-counting myth and explains the powerful biological system that controls our weight: the "set point." He reveals how our modern diet and lifestyle have broken this system, but also provides a clear, science-backed path to fixing it. Dr. Andrew Jenkinson is a consultant bariatric surgeon and the author of Why We Eat (Too Much): The New Science of Appetite. In this episode, you’ll learn: Why the idea that weight loss is simply about willpower is a damaging myth. The science of the "weight set point" and how your brain fights to keep you at a certain weight. How your metabolism acts like a "dimmer switch," slowing down to prevent weight loss when you diet. The crucial role of hormones like leptin and insulin, and why our modern diet causes "leptin resistance" — the reason your brain can’t tell it’s full. How yo-yo dieting can actually raise your set point, making you heavier in the long run. A practical, step-by-step plan to lower your set point by changing what you eat, not just how much. The truth about new weight-loss drugs like Ozempic and their long-term effects.

    Recap: Why you should eat 30 different plants every week | Hugh Fearnley-Whittingstall & Tim Spector
    Oct 7 2025
    Today, we’re talking about plants. For years, our diets have been guided by a simple three word slogan: ‘five a day’. While it’s well established that eating fruit and vegetables is good for us, some experts believe the ‘five a day’ message puts too much emphasis on quantity, and not enough on variety. So, is time to adjust our guiding plant principle? I’m joined by Professor Tim Spector and chef Hugh Fearnley-Whittingstall, who advocate for a new goal: eating 30 different plants each week. Together, we’ll explore why diversity is key for your microbiome and share some delicious ways to bring more plants onto your plate. 🌱 Try our new plant based wholefood supplement - Daily30+ *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system 📚 Books from our ZOE Scientists: The Food For Life Cookbook by Prof. Tim Spector Food For Life by Prof. Tim Spector Every Body Should Know This by Dr Federica Amati Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - for a healthier microbiome in weeks Have feedback or a topic you'd like us to cover?
