基礎代謝計算機

Calculate your basal metabolic rate (BMR), the energy your body uses at complete rest, using the Mifflin–St Jeor, revised Harris–Benedict or Katch–McArdle equation.

この計算機の使い方

  1. Choose a formula. Mifflin–St Jeor is the most widely recommended for the general population.
  2. Enter age, sex, height and weight. For Katch–McArdle, enter your body fat percentage instead of relying on age and sex.
  3. See your BMR and estimated daily needs at each activity level.

計算式

Each equation was derived from measured metabolic rates in study populations.

Mifflin–St Jeor: 10W + 6.25H − 5A + 5 (men) or − 161 (women)
Harris–Benedict (revised): 88.362 + 13.397W + 4.799H − 5.677A (men); 447.593 + 9.247W + 3.098H − 4.330A (women)
Katch–McArdle: 370 + 21.6 × lean body mass (kg)

Example

  1. Woman, 30 years, 165 cm, 60 kg (Mifflin–St Jeor).
  2. BMR = 600 + 1,031.25 − 150 − 161 = 1,320 kcal/day.

よくある質問

What is the difference between BMR and RMR?

BMR is measured under strict conditions (fasted, fully rested, thermoneutral). Resting metabolic rate (RMR) is measured under less strict conditions and is slightly higher. The terms are often used interchangeably.

Which formula is most accurate?

Studies generally find Mifflin–St Jeor the most accurate for healthy adults. Katch–McArdle can be better for lean, muscular people if body fat is known accurately.

Can I increase my BMR?

Building muscle raises BMR modestly. BMR declines with age and with weight loss.
