BMR 계산기

We estimate BMR with the Mifflin–St Jeor equation using your sex, age, weight, and height. It predicts resting energy needs in kilocalories per day under standardized “at rest” assumptions.

Your true resting metabolism can differ because of genetics, thyroid disease, medications, stress, sleep, and body composition.

BMR is the bottom layer of your energy budget—the calories you would need to run organs and basic functions before intentional movement.

It is not your total daily calorie need. For maintenance calories in real life, use TDEE (BMR plus activity) or discuss targets with a registered dietitian.

Use recent weight; large fluid shifts can skew short-term readings.

If you are pregnant, breastfeeding, or under medical supervision for eating or endocrine disorders, treat any number as illustrative only.

Compare changes over time with the same equation and inputs rather than jumping between different apps that use different formulas.

All predictive equations have error. Clinical indirect calorimetry is more accurate when available.

This calculator does not replace medical nutrition therapy or prescriptions for weight change.
