Most conversations about how to reverse biological age focus on what to take, what to eat, or what to optimize. This one starts somewhere different.
Dr. Kavin Mistry is a board-certified neuroradiologist with 25 years of clinical experience — and someone who spent formative years living with the Hadza tribe in Tanzania, one of the last remaining hunter-gatherer populations on earth. That combination of modern neuroscience and ancestral immersion led him to a framework built around a single question: what conditions did human biology actually evolve to require — and what does it cost us when those conditions are absent?
His answer is the foundation of Primal Health Design: 7 Key Paradigms to Reverse Biological Age. And in this conversation with Dr. Gil, he walks through all seven.
What you’ll learn:
The science of biological age — what it actually measures, why it diverges from chronological age, and what moves the needle in either direction.
What the Blue Zones research reveals about populations who consistently reverse their biological age — and what most summaries of that research miss entirely.
The seven paradigms of Primal Health — Earth, Body, Food, Mind, Purpose, Tribe, and Cosmos — and how each one operates as a biological variable, not just a lifestyle preference.
Why purpose and belonging are not soft wellness concepts. They are measurable inputs that affect inflammatory signaling, immune function, and longevity in ways that most clinical frameworks still don’t account for.
What Dr. Mistry learned living with the Hadza that no medical training had prepared him for — and why their relationship to movement, food, community, and rest produces a biology that conventional medicine struggles to explain.
How to apply ancestral health principles to a modern life without turning them into another rigid protocol that adds stress rather than reducing it.
This is a different kind of AskDrGil episode. Less about patterns and psychology, more about the biological ground underneath. If you have been working on the deeper layers of your health and wondering what the physiological foundation needs — this conversation is for that.
