#208: Herman Pontzer, PhD - Constrained Energy Expenditure Model & the Evolutionary Biology of Energy Balance
Dec 6, 2017
Herman Pontzer, an evolutionary biologist, discusses the constrained energy expenditure model, physical activity paradox, and why humans can expend so much energy in short time frames. The podcast challenges beliefs about calorie burn and activity levels, delves into evolutionary biology of energy balance, and explores the impact of physical activity on health and disease.

- Constrained energy expenditure model suggests adaptations maintain stable calorie burning regardless of activity level.
- Evolutionary biology influences the body's tendency to stabilize energy expenditure despite varying activities.
Deep dives
Daily Exercise May Not Significantly Alter Daily Energy Expenditure
Increasing physical activity levels may lead to short-term higher energy expenditure, but over time, the body adjusts to maintain a similar daily energy expenditure, research suggests.
