The Harris-Benedict Formula
This is a calorie formula using factors such as age, sex, weight, and height to determine the BMR. The lean body mass is not taken into consideration in this method.
Men: BMR = 66 + (13.7 x wt in kg) + (5 x ht in cm) - (6.8 x age in years)
Women: BMR = 655 + (9.6 x wt in kg) + (1.8 x ht in cm) - (4.7 x age in years)
