What is BMR?
Basal Metabolic Rate is the number of calories your body burns at complete rest — just to keep organs functioning. It accounts for 60–75% of your total daily calorie expenditure.
The Mifflin-St Jeor formula
Male: BMR = 10×kg + 6.25×cm − 5×age + 5
Female: BMR = 10×kg + 6.25×cm − 5×age − 161
How to use your BMR
Multiply BMR by your activity factor to get TDEE. Eat below TDEE to lose weight, above to gain. BMR itself is your absolute floor — never eat below it without medical supervision.
