Metabolism Calculator (BMR/TDEE)

BMR is calories burned at complete rest. TDEE includes your activity level and represents total daily calorie expenditure.

The Mifflin-St Jeor equation (used here) is considered the most accurate for most adults according to the American Dietetic Association.

Eat 500 calories below your TDEE to lose approximately 1 pound per week. Never go below 1,200 calories (women) or 1,500 (men) without medical supervision.
