The total amount of calories an individual burns in a given day is known as total daily energy expenditure (TDEE) and it comes from several sources including RMR, the thermogenic effect of food (TEF), non-exercise activity thermogenesis (NEAT), excess post-exercise oxygen consumption (EPOC) and, of course, exercise (Ex).

Total energy expenditure (TEE) consists of four components, i.e., the sleeping metabolic rate (SMR), the energy cost of arousal, the thermic effect of food or diet-induced energy expenditure (DEE), and the energy cost of physical activity or AEE. Physical activity is the extra energy you burn every day by being physically active. 2. Energy expenditure is measured by indirect calorimetry or calculated using mathematical equations.
