This episode is part of our Fan Favorites series, where we bring back some of our most loved conversations for anyone who missed them the first time around. This episode with Tim Spector is a must!
In this episode of The Healthspan Collective, host Nicole Doran sits down with Tim Spector, professor at King’s College London and co-founder of Zoe, to challenge almost everything we think we know about nutrition. Drawing on decades of twin research, Tim reveals that identical twins share only about 25% of their gut microbes, meaning the advice that works for someone else may be doing nothing or even working against you, and that genes play a far smaller role in how your body responds to food than most people assume.
This is one of those conversations that genuinely changes how you think about what you eat. Tim breaks down the case for fiber, plant diversity, and fermented foods in a way that is practical and evidence-backed, while taking on some of the biggest nutrition debates of the moment including carnivore diets, seed oils, protein obsession, and the myth that calories are the whole story. If you have ever felt confused by conflicting nutrition advice, this episode is the reset you need.
