基礎代謝量(BMR)計算機 — 基礎代謝の推定と消費エネルギー
基礎代謝量(BMR)とは?
基礎代謝量(BMR: Basal Metabolic Rate)は、人間が覚醒状態で生命を維持するために最低限必要なエネルギー量(呼吸、心臓の拍動、体温維持など)のことです。1日の総消費カロリーの約60%〜70%を基礎代謝が占めており、効率的なダイエットや筋肉増量において最も重要な指標となります。
Mifflin-St Jeor式によるBMR計算公式
最も信頼性が高いとされるミフリン・セントジョール式を採用:
- 男性:
BMR = 10 × 体重(kg) + 6.25 × 身長(cm) − 5 × 年齢 + 5 - 女性:
BMR = 10 × 体重(kg) + 6.25 × 身長(cm) − 5 × 年齢 − 161
Frequently Asked Questions
To calculate your BMR (Basal Metabolic Rate), use the Mifflin-St Jeor formula: For Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in yrs) + 5. For Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in yrs) - 161. Alternatively, enter your metrics into the CalculatorsDaily BMR Calculator for instant results.
BMR stands for Basal Metabolic Rate. It represents the baseline number of calories your body burns in a 24-hour period while at complete rest to perform life-sustaining internal functions like breathing, blood circulation, cellular repair, and brain activity.
To calculate BMR for Indians, the standard Mifflin-St Jeor formula is widely used. Because South Asian populations tend to have a higher body fat percentage at a lower BMI, health researchers and ICMR guidelines suggest combining standard BMR equations with accurate body composition measurements (lean mass) or using modified ICMR metabolic reference standards.
An average BMR for adult females ranges between 1,300 and 1,500 calories per day, depending on age, height, weight, and muscle mass. A 'good' BMR is simply one that accurately reflects healthy lean muscle mass and metabolic function for your specific body size.
No, you should not restrict your food intake down to your BMR. BMR is the energy your body needs strictly for involuntary survival functions. To lose weight safely, calculate your Total Daily Energy Expenditure (TDEE) and create a 300 to 500 calorie deficit below TDEE while eating at or slightly above your BMR.
A BMR around 1,000 calories typically occurs in petite individuals (shorter height under 5 feet / 150 cm), older adults with lower lean muscle mass, or individuals experiencing metabolic adaptation from prolonged extreme calorie restriction.
