In this episode, we’re joined by the brilliant Dr. Tim Spector—Professor of Genetic Epidemiology, founder of the renowned TwinsUK study, and co-founder of the science-driven nutrition company ZOE. Known for his groundbreaking research featured in the Netflix documentary Hack Your Health and over 900 published studies, Dr. Spector dives into the fascinating science of the gut microbiome, why identical twins don’t respond the same to food, and how ZOE’s massive nutrition study (published in Nature Medicine) is transforming how we understand personalized health. We unpack the science behind fiber (why he eats 30 different plants a week), what improves or damages your microbiome, and how gut health ties directly to mood, sleep, and metabolic health. Dr. Spector also shares his thoughts on mental well-being, the real issue behind the rise of protein, and offers an early peek at the new Processed Food Risk Scale. If you’re looking to go beyond basic nutrition advice and get into the real science of food, microbes, and health, this is the episode for you.
