Total energy expenditure (TEE) is the energy expended during oxidation of energy-yielding macronutrients within a 24-hour period. TEE includes three core components: resting metabolic rate, or resting energy expenditure (REE); the thermic effect of food (TEF), also referred to as diet-induced thermogenesis (DIT); and physical …
