Calculating Your Basal Metabolic Rate (BMR)
Resumen
Basal metabolic rate (BMR) is the number of calories your body burns at complete rest just to stay alive — breathing, circulation, cell repair. It is the foundation for any calorie or weight plan. This calculator estimates your BMR from age, sex, height, and weight in your browser.
Cómo usar (paso a paso)
- 1
Enter age, sex, height, and weight
These four inputs drive the Mifflin-St Jeor formula.
- 2
Read your BMR
The result is your resting daily calorie burn.
- 3
Apply an activity factor
Multiply by your activity level to estimate total daily calories (TDEE).
Cómo Funciona
The tool uses the Mifflin-St Jeor equation, the most accurate widely used BMR formula, which combines weight, height, age, and sex into a daily resting calorie figure. BMR is not your full daily burn — multiplying it by an activity factor gives total daily energy expenditure (TDEE), the calories you actually use. Knowing BMR lets you set a sensible calorie target for maintenance, loss, or gain.
Cuándo usarlo
Setting a starting point for a calorie plan. Understanding the minimum calories your body needs at rest. Calculating TDEE by applying an activity multiplier.
Preguntas Frecuentes
BMR is calories burned at rest; TDEE adds the calories from daily activity and exercise. TDEE is BMR multiplied by an activity factor.
Notas Importantes
BMR figures are estimates for informational purposes only and are not medical advice. Individual metabolism varies with body composition, health conditions, and medication — consult a qualified healthcare professional before changing your diet.
