• 77. Professor Tim Spector: Your Gut Bacteria Control Your Health More Than Your DNA

  Your doctor says your health problems are genetic, so you're destined for the same fate. But what if that's completely wrong? In this episode of Extend, I'm joined by Professor Tim Spector, one of the world's leading microbiome researchers, to reveal the truth: your gut bacteria have more control over your health than your genes do. We explore Tim's 30-year twin study that turned modern medicine upside down, the devastating effects of antibiotics on your internal ecosystem, and why ultra-processed foods are as dangerous as cigarettes. We also dive into why 95% of Americans are dangerously fiber-deficient, and how fermented foods can reduce inflammation like natural steroids.   Professor Tim Spector is a genetic epidemiologist at King's College London, co-founder of Zoe, and author of multiple bestselling books on the microbiome. His research on 16,000 twins has revolutionized our understanding of how gut health trumps genetics in determining health outcomes.   We Also Discuss: (02:18) 30 Years of Twin Research: The Study That Changed Everything  (08:35) The Antibiotic Crisis: Why Your Childhood Meds Are Still Hurting You  (11:31) C.

  What if the real reason you’re gaining weight, feeling wired, or struggling to nourish your family isn’t about willpower—but the culture you live in? On this episode of Extend, I’m joined by Shawn Stevenson—nutritionist, bestselling author, and host of The Model Health Show—to explore how our food environment, not personal discipline, is fueling the chronic disease crisis. If you’re raising kids, trying to eat better, or just feel overwhelmed by ultra-processed foods, this conversation cuts through the noise. We unpack the science behind shared meals, how family dinner regulates your stress hormones, why many “healthy” foods aren’t, and what it takes to create a home culture that supports real health.
