About the BMR & Calorie Calculator
Your BMR — basal metabolic rate — is the energy your body burns just staying alive, and multiplying it by an activity factor gives your TDEE: the calories you actually burn per day. This calculator uses the Mifflin-St Jeor equation, the most accurate general formula, from your age, sex, height and weight, then presents TDEE across five activity levels plus the calorie targets for losing (−500 kcal) or gaining (+500 kcal) weight sensibly.
