Understanding Your BMR
Your BMR is the number of calories required to keep your body functioning at rest. To calculate your total daily calorie needs (TDEE), this number is multiplied by an activity factor.
About BMR
Your Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate BMR formulas.
- Men: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age + 5
- Women: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age - 161
