Question

Quizplus · Accepted Answer

The three components of total energy expenditure are basal metabolic rate (which accounts for the majority of energy expenditure at rest), physical activity (which varies based on level of activity), and the thermic effect of food (which is the energy required for digestion, absorption, and metabolism of food). Adaptive thermogenesis is a fourth component that can impact energy expenditure, but it is not considered as one of the core components of total energy expenditure. Sleep activity, while important for overall health and well-being, does not contribute significantly to energy expenditure.
