What are the three main components of total energy expenditure?

Question

Quizplus · Accepted Answer

The three main components of expenditure are basal metabolism (the energy required for basic bodily functions at rest), physical activity (the energy required for movement and exercise), and the thermic effect of food (the energy required for digestion and absorption of food). Thyroid activity and environmental temperature can affect expenditure, but they are not considered main components. Mental activity can also increase energy expenditure, but it is not a separate component as it falls under physical activity.
