How this calculator works
Mifflin–St Jeor estimates resting energy: 10 × weight (kg) + 6.25 × height (cm) − 5 × age + a sex coefficient (+5 male, −161 female). This estimate is commonly used as BMR in calorie calculators.
TDEE = BMR × activity factor: 1.2 sedentary, 1.375 light, 1.55 moderate, or 1.725 active. Activity factors are planning approximations, not measured expenditure.
