what are the three main components of total energy expenditure
Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA).RMR constitutes 60 to 75% of daily energy expenditure and is the energy associated with the maintenance of major body functions.MR accounts for the largest portion of daily energy expenditure no matter whether youâre sedentary or very active â 80 to 56% respectively (Landsberg, et al., 2009). Energy expenditure from exercise/activity is thus small relative to the energy expenditure at rest.
