Question

Quizplus · Accepted Answer

Basal metabolic rate (the energy needed for basic bodily functions), physical activity, and the thermic effect of food (the energy needed to digest and absorb nutrients) are the three main components of total energy expenditure. Adaptive thermogenesis (changes in metabolic rate due to environmental or physiological factors) is a smaller contributor to total energy expenditure. Sleep activity is not typically included as a component of total energy expenditure.
