    BMR — basal metabolic rate — is the number of calories your body burns at complete rest just to keep vital functions running. Multiplied by an activity factor, it gives your total daily energy expenditure (TDEE): the number of calories you actually need each day. Use the calorie targets above as a starting point, not a prescription.
