Quizplus · Accepted Answer

The thermic effect of food contributes the smallest amount of energy expended over a 24-hour period. This refers to the energy used by the body to digest, absorb and metabolize the food we eat, which ranges from 5-10% of total energy expenditure. Resting metabolism, basal metabolic rate, and physical activity all contribute significantly more to energy expenditure.
