Women: BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161
Women: BMR = (10 × kg) + (6.25 × cm) − (5 × age) − 161
Harris-Benedict (Revised 1984)
Men: BMR = 88.4 + (13.4 × kg) + (4.8 × cm) − (5.7 × age)
Women: BMR = 447.6 + (9.2 × kg) + (3.1 × cm) − (4.3 × age)
Women: BMR = 447.6 + (9.2 × kg) + (3.1 × cm) − (4.3 × age)
