Find out how many calories your body burns at complete rest — the foundation of all weight management planning.
Mifflin-St Jeor equation (2005). BMR is your calorie floor — never eat below this for extended periods.
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic life functions — breathing, circulation, cell production — while at complete rest. It represents the minimum energy your body requires to survive.
BMR is your resting calorie burn. TDEE (Total Daily Energy Expenditure) multiplies BMR by your activity level to give your actual daily calorie needs. Most women should eat at or above their TDEE to maintain weight, or below it to lose weight.
Women typically have a lower BMR than men of the same height and weight due to differences in muscle mass and hormonal profiles. The Mifflin-St Jeor equation accounts for this with a female-specific adjustment of -161 calories.
