Question

Quizplus · Accepted Answer

The three main components of total energy expenditure are basal metabolism (energy needed for basic bodily functions), physical activity (energy needed for exercise and movement), and thermic effect of food (energy needed for digestion and absorption of nutrients). Thyroid activity and environmental temperature may influence energy expenditure but are not primary components. Mental activity may slightly increase energy expenditure but is not a significant component.
