The duration of human maturation has been underestimated; an additional 4–6-year pre-
adult period of “emerging adulthood,” should be included in models of human maturation. It …

ABSTRACT A common, long‐held belief is that metabolic rate drives the rates of various
biological, ecological and evolutionary processes. Although this metabolic pacemaker view …

The high energetic costs of human brain development have been hypothesized to explain
distinctive human traits, including exceptionally slow and protracted preadult growth …

Current obesity prevention strategies recommend increasing daily physical activity,
assuming that increased activity will lead to corresponding increases in total energy …

Humans are distinguished from the other living apes in having larger brains and an unusual
life history that combines high reproductive output with slow childhood growth and …

The limits on maximum sustained energy expenditure are unclear but are of interest
because they constrain reproduction, thermoregulation, and physical activity. Here, we show …

The carnivoran giant panda has a specialized bamboo diet, to which its alimentary tract is
poorly adapted. Measurements of daily energy expenditure across five captive and three …

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 …

Humans and other species adapt dynamically to changes in daily physical activity,
maintaining total energy expenditure within a narrow range. Chronic exercise thus …

Objectives Studies of total energy expenditure,(TEE; kcal/day) among traditional populations
have challenged current models relating habitual physical activity to daily energy …
