WebMar 22, 2024 · Constrained Energy Expenditure and the Case for Human Design. In many ways, constrained energy expenditure functions as an ingenious design to ensure human survival. For most of human history, our ancestors lived as hunter-gatherers—a highly active, physically demanding way of life. Yet when hunting and foraging for food, … WebDec 18, 2024 · Trade-offs in energy allocation between competing physiological tasks, within a constrained energy budget, appear to shape childhood phenotypic variation (e.g., patterns of growth). These trade-offs may contribute to the lifetime obesity and metabolic health disparities that emerge during rapid economic development. INTRODUCTION
