About this calculator
Basal metabolic rate is the energy your body uses at complete rest. The result uses the Mifflin-St Jeor equation, with the revised Harris-Benedict value for comparison.
The formula
Mifflin-St Jeor: 10×kg + 6.25×cm − 5×age + 5 (men) or − 161 (women)
Worked exampleMan, 30, 75 kg, 178 cm → 10×75 + 6.25×178 − 5×30 + 5 = about 1,718 kcal/day.
