Find your Basal Metabolic Rate — calories burned at complete rest.
Your Basal Metabolic Rate (BMR) is the number of calories your body burns just to stay alive at complete rest. This tool uses the accurate Mifflin-St Jeor equation. Multiply your BMR by an activity factor to get your total daily calorie needs.
The energy (calories) your body needs at rest to keep basic functions like breathing and circulation going.
BMR is at rest; TDEE adds the calories you burn through activity. Use our calorie calculator for TDEE.
