Resting metabolic rate estimator

Estimate adult resting energy expenditure with Mifflin–St Jeor.

How it works and limits

For adults 19–78 years, the age range in the original study. The equation uses the study’s sex-specific coefficients: 10 × kg + 6.25 × cm − 5 × years + coefficient. This is resting energy, not total daily needs or a calorie intake target. It is not suitable for children, pregnancy, illness or clinical nutrition decisions. Individual needs can differ substantially.
