Herman Pontzer is an American evolutionary anthropologist at Duke University, where he is associate professor of evolutionary anthropology and global health.[1] He is known for his research into human bioenergetics.[2][3][4]
Constrained daily energy expenditure model
In the context of the exercise paradox—where increased physical activity does not always lead to weight loss—Pontzer helped develop a theory of human metabolism known as the "constrained daily energy expenditure model". According to this theory, total daily energy expenditure is not simply the sum of separate metabolic processes (such as basal metabolism, movement, digestion, reproduction, and immune function). Instead, energy expenditure increases with activity only up to a certain point, after which it plateaus. This suggests that humans have evolved a biological constraint that limits the total amount of energy expended per day.[5]
