Estimated lean mass—

BMR estimates energy at rest. When body-fat percentage is provided, the tool also estimates lean mass and compares models that may better reflect people whose body composition differs from the average built into simpler equations.

Mifflin-St Jeor uses weight, height, age and sex coefficient. It is the default reference when body-composition data is not available.
