About this episode

Lauren interviews Eric about his research on metabolism, energy expenditure, and the evolutionary aspects of human energy regulation.

Lauren interviews Eric about his research on metabolism and energy expenditure. He describes turning down a tenure-track job to move into science communication and then evolutionary anthropology, studying how humans regulate their energy budget. He explains why people get metabolism wrong in both directions — treating it as mysterious and stretching the real person-to-person variation to impossible extremes — and walks through metabolic adaptation, why reverse dieting usually backfires, and the evolutionary logic of the body's "low-power mode." They get into why resting metabolic rate doesn't crater at menopause (the real changes from 20 to 60 are mostly behavioral), how non-exercise activity works and its limits, and what hunter-gatherer and subsistence populations reveal as a kind of "control group" for modern health. He closes with simple public-health advice — sell people on physical activity, find a sustainable calorie-appropriate eating pattern, get enough fiber from whole food sources — and discusses the ongoing debate over the constrained energy expenditure model.
