How it works

BMR uses the Mifflin-St Jeor equation, the most accurate widely-used formula:

Men: 10·kg + 6.25·cm − 5·age + 5
Women: 10·kg + 6.25·cm − 5·age − 161

TDEE = BMR × activity multiplier. To lose weight steadily, eat ~500 kcal under TDEE (≈0.5 kg / 1 lb per week). To gain, add ~300 kcal for clean lean-mass gains.
