Basal Metabolic Rate (BMR) is the number of calories your body burns at complete rest to maintain basic life functions: breathing, circulation, cell production, and temperature regulation.
Mifflin-St Jeor (1990):
Men: 10W + 6.25H - 5A + 5
Women: 10W + 6.25H - 5A - 161
Harris-Benedict (1919, revised 1984):
Men: 88.362 + 13.397W + 4.799H - 5.677A
Women: 447.593 + 9.247W + 3.098H - 4.330A
TDEE (Total Daily Energy Expenditure) = BMR × Activity Multiplier. This is your actual maintenance calorie target. To lose weight, subtract 300-500 kcal. To gain, add 300-500 kcal.
