Verywell Fit content is rigorously reviewed by a team of qualified and experienced fact checkers. The resting energy expenditure can be calculated using the fallow Harris-Benedict Formula: Male: 66,47 + 13,75 (body mass in Kg) + 5 (stature in cm) - 6,8 (age in years) Female: 665 + 9,6 (body mass in Kg) + 1,8 (stature in cm) -4,7 (age in years) 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). /Length 920 effects of eating or drinking, smoking, temperature, etc. The only way to be fairly sure that the true average Lange Andersen, K., R.
