What are the major components of energy expenditure?

Question

Quizplus · Accepted Answer

BMR (Basal Metabolic Rate) is the energy expended at rest just to maintain bodily functions. TEF (Thermic Effect of Food) is the energy expended to digest, absorb, and metabolize food. Physical activity includes the energy expended during exercise and any other physical movements, such as walking or standing. These three components make up the majority of energy expenditure, with BMR accounting for around 60-70%, physical activity accounting for 15-30%, and TEF accounting for approximately 10% of total energy expenditure. Protein metabolism and sleeping are not major components of energy expenditure.
