Rethinking Metabolism: Insights from Hunter-Gatherers
This chapter challenges traditional beliefs about metabolism and calorie burning by examining research on modern hunter-gatherer communities, particularly the Hadza people. Despite their high levels of physical activity, findings indicate that their overall energy expenditure is comparable to that of sedentary individuals, suggesting a complex relationship between activity and calorie burn. The chapter explores the theory of constrained daily energy expenditure, highlighting the body's adaptation to physical exertion and energy conservation over time.
