CalculatorsBasal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain vital functions—breathing, circulation, cell production, and more. It accounts for 60–75% of your total daily energy expenditure.
TDEE (Total Daily Energy Expenditure) multiplies your BMR by an activity factor. To maintain weight, eat around your TDEE. To lose weight, eat 250–500 kcal below; to gain, eat 250–500 kcal above.
