The human body adapts dynamically to maintain total energy expenditure (TEE) within a narrow physiological range. Rather than increasing with physical activity in a dose-dependent manner, experimental and ecological evidence suggests the hypothesis that TEE is a relatively constrained product of our evolved physiology.

The body adapts to changes in physical activity to keep total energy expenditure in check.
