Three factors affect total daily energy expenditure (TDEE): 1) Resting metabolic rate (RMR) Lower recovery HR, shows you have higher VO2 max. The DEE, as observed in a respiration chamber over 24 h has been evaluated in different ways: (1) as the difference in 24-h energy expenditure between a day in the fed state and a day in the fasted state, (2) . Total Energy expenditure is the amount of calories burned by the human body in one day adjusted to the amount of activity (sedentary, moderate or strenous).
