Dr. Herman Pontzer of Duke is on the show this week to talk about human metabolism and his new book, Burn. He helps answer questions like: How much energy can a person burn in one day? Does exercise help you lose weight? Do people with different subsistence strategies have different metabolisms? We also talk about his work with the Hadza.
