Dr. Herman Pontzer: How We Really Burn Calories & Lose Weight

My guest is Dr. Herman Pontzer, Ph.D., a professor of evolutionary
anthropology and global health at Duke University, known for his
research on human bioenergetics, particularly energy expenditure
and the exercise paradox. We discuss his work comparing highly
active hunter-gatherer groups to more sedentary cultures, exploring
their total energy expenditure and the surprising similarities. We
examine the impact of factors such as age, sex, exercise, and
pregnancy on daily energy expenditure. We also break down whether
diet or exercise plays a greater role in weight management and
weight loss. Additionally, we explore how genetics and the
environment interact to shape human physiology, highlighting how
population-level findings often overlook individual variation and
emphasizing the need for medical and diagnostic practices to
account for this diversity. Read the full episode show notes at
