How It Works

The Mifflin-St Jeor equation is widely considered the most accurate BMR formula for the general population:

Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5

Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161

TDEE (Total Daily Energy Expenditure) = BMR × activity factor.
