*Content warning up top: This episode discusses sensitive themes like diet culture, caloric intake, the psychological & physical effects of food restriction and includes many listeners’ personal experience with the term “obesity." It may be triggering for those with a history of or sensitivity to disordered eating. We also discuss the Body Mass Index, still used by medical professionals, but acknowledged by many sociologists to be rooted in structural oppression.*

Let’s explore our human machinery. And talk about Brazilian butt lifts. Professor of Evolutionary Anthropology and metabolism researcher Dr. Herman Pontzer gives us the data on mitochondrial backstories, muscle mass and hormones, our expanding brains, the flaws of the Body Mass Index, humans’ relationships with nutrition, why crash dieting can change your metabolism, perspectives on sticky medical terms, isotope magic, how much exercise hunter gatherers get, carnivore diets, scales, and what to do if you're grappling with sadness.
