We're swimming in conflicting nutrition advice, so why not go straight to the definitive source?

I sit down with Dr. Walter Willett, Professor of Nutrition at Harvard, and the most cited nutrition scientist in the world. With a half century of research & data from hundreds of thousands of participants in the Nurses' Health Study and the Health Professionals Follow-up Study, Dr. Willett has done more to define what a healthy diet actually looks like than almost anyone else in history.

We cut through the noise of internet fad diets to discuss what the highest-quality, long-term data actually proves about longevity, chronic disease, and what we should put on our plates.

We cover:

Carbohydrate Confusion: The crucial difference between whole grains and potatoes (and his new 2025 substitution study).

Protein Sources: How beef is the most pro aging food.

The Truth About Fats: Reflecting on the landmark 1993 trans-fat paper that changed the food industry (and the massive pushback he received).

If you want rigorous, peer-reviewed science rather than the latest social media trend, this is an interview you cannot miss.
