šŸ„‘ Make smarter food choices. Become a member at http://zoe.comĀ  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 ā€œeat less, move moreā€ 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. How managing stress and improving sleep can be as important as your diet for sustainable weight management 🌱 Try our new plant based wholefood supplement - Daily30: https://zoe.com/daily30?utm_medium=zoe_podcast&utm_source=podcast_platform&utm_campaign=d30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system Follow ZOE on Instagram |Ā  https://www.instagram.com/zoe/ Timecodes 00:00 Introduction 00:20 Is gaining weight as we age inevitable? 01:38 Why ā€˜eat less, move more’ is a myth 03:53 Is your weight predetermined by your genes? 06:36 How your mother's experience in the womb can alter your dna 10:35 Why most diets are doomed to fail in the long term 12:16 Your brain has a weight 'set point' it tries to defend 15:27 The 'weight anchor': your body's powerful defence against weight loss 17:22 The reason you often end up heavier after a diet 19:00 A shocking study: yo-yo dieting made mice fatter than a junk food diet 21:35 The 'joker in the pack' controlling 70% of your energy burn 23:12 Your body has a hidden metabolic 'dimmer switch' 27:53 The mystery of the missing calories 32:35 Why dieting can actually raise your weight set point 34:31 The master hormone that tells your brain when you're full 36:08 The hidden reason your brain can't tell you're full 37:35 Why feeling hungry and lazy are symptoms, not causes, of obesity 39:00 The 'broken gas tank meter' analogy for weight gain 41:26 Step 1 for resetting your weight: the 30-day challenge 42:07 Why you need to stop snacking between meals 43:50 What is mindful eating and why does it matter? 46:22 Can time-restricted eating lower your set point? 48:37 The truth about new weight loss drugs like ozempic 50:28 The surprising impact of stress and sleep on your weight 51:42 The single most important thing to understand about weight loss šŸ“šBooks by our ZOE Scientists The Food For Life Cookbook Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in WeeksĀ  Better Breakfast Guide
