Michael Pollan: The TRUTH about junk food and why you can’t stop eating

If you feel like you can’t stop eating, constantly crave junk food, or struggle with overeating, this episode will change how you see food. Michael Pollan, one of the world's most influential science writers, joins Professor Tim Spector to explain how ultra-processed food may drive food addiction, override fullness signals, and keep us craving more. Together, they explore why foods high in sugar, salt, and fat can feel so hard to resist, and what we can do to fight back. Michael and Tim unpack how the modern food system changed over the last 50 years, and why many ultra-processed foods are designed around “craveability.” They explain how these foods may stimulate the brain’s reward systems, why fibre and plants help us feel fuller, and why cooking more meals at home may help reduce overeating without calorie counting. The episode includes practical ways to regain control of your eating habits, reduce cravings, feel better and live more healthy years. If your cravings feel impossible to control, is it really a lack of willpower, or is modern food engineered to keep us coming back for more? 🌱 Try our science-backed and tasty wholefood supplement Daily30: https://zoe.com/daily30?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=d30 Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE: https://zoe.com/buymembership?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=BAU Follow ZOE on Instagram | https://www.instagram.com/zoe/ Timecodes 00:00 Can ultra-processed food hijack your brain? 04:04 How monoculture changed modern food 08:52 Are we basically made of corn? 12:58 The 3 ingredients engineered to drive cravings 14:32 Why ultra-processed food keeps you hungry 15:44 Why governments subsidize junk food 18:01 How fast food changed family cooking 20:00 Is ultra-processed food destroying family meals? 21:46 What happens when you stop eating plants? 22:55 Your gut microbes are eating too 25:31 Caffeine and the world’s most used drug 26:26 Michael Pollan quits caffeine for 3 months 28:35 Is caffeine addiction actually harmful? 29:11 Coffee and heart disease risk explained 32:34 Why workplaces normalized caffeine 33:40 The simplest way to stop overeating 35:30 Did food companies convince us cooking is hard? 37:02 How to identify ultra-processed food 38:25 Michael Pollan’s famous food rule explained 40:14 Why “plant-based” doesn’t always mean healthy 42:46 The Japanese habit that may reduce overeating 44:24 How food companies engineer craveability 45:25 Are food companies manipulating your cravings? 46:41 Why eating 30 plants a week matters 47:36 Eat food, not too much, mostly plants 📚Books by our ZOE Scientists The Food For Life Cookbook | https://amzn.to/4amfIMX Every Body Should Know This by Dr Federica Amati | https://amzn.to/4blJsLg Food For Life by Prof. Tim Spector | https://amzn.to/4amZinu Ferment by Prof. Tim Spector | https://amzn.to/4hU1Df5 Good Mood Food (preorder) by Prof. Tim Spector | https://amzn.to/4l9oXat Free resources from ZOE: The Hormone Harmony Guide: Tuning Your Body’s Internal Orchestra | http://ZOE.com/hertility?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=hertility Eating for Better Brain Health: Your brain-gut blueprint | https://ZOE.com/brainhealth?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=betterbrainhealth How to eat in 2026 - Discover ZOE’s 8 nutrition principles for long-term health | https://zoe.com/2026?utm_medium=zoe_podcast&utm_source=youtube&utm_campaign=How to eat in 2026 Live Healthier: Top 10 Tips From ZOE Science & Nutrition | https://zoe.com/freeguide?utm_medium=podcast&utm_source=youtube&utm_campaign=freeguide Gut Guide - For a Healthier Microbiome in Weeks | https://zoe.com/gutguide?utm_medium=podcast&utm_source=youtube&utm_campaign=gutguide Better Breakfast Guide | https://zoe.com/breakfastguide?utm_medium=podcast&utm_source=youtube&utm_campaign=breakfastguide Mentioned in today's episode Why should you eat 30 plants a week? | https://zoe.com/learn/30-plants-per-week?
