Adult BMR uses the published Mifflin-St Jeor equation. BMR estimates resting energy expenditure and does not include activity. Actual needs vary substantially. Do not use this tool as a diet prescription; pregnancy, illness, eating-disorder concerns, youth, or medically supervised nutrition require qualified care.

How this tool works

The estimate uses the Mifflin-St Jeor adult equation with age, height, weight, and the selected sex-based equation.

Limits to know

The Mifflin-St Jeor result is a population estimate of resting energy expenditure, not a direct metabolic measurement. Body composition and individual physiology can produce meaningful differences.
