Find your Basal Metabolic Rate — the calories your body burns while resting.
The Mifflin-St Jeor equation, using weight (W, kg), height (H, cm) and age (A).
Men: 10W + 6.25H − 5A + 5
Women: 10W + 6.25H − 5A − 161
Why is the formula different for men and women?
On average, men and women have different body makeup, especially muscle mass, which affects how many calories you burn at rest. The formula's fixed number accounts for this average difference.
