Basal and total metabolic rate
The calculator estimates your daily calorie needs. The basal metabolic rate (BMR) is the energy your body uses at complete rest; the total (TDEE) additionally accounts for your physical activity.
- Mifflin-St Jeor: The most common formula today for estimating BMR from sex, weight, height and age.
- Activity factor: From a sedentary lifestyle (×1.2) to extremely active (×1.9).
- Targets: For weight loss about 500 kcal below, for gain 500 kcal above the total – as a rough guide.
