基礎代謝量（BMR）計算ツール：ダイエットと筋肉増強をサポート
The Basal Metabolic Rate (BMR) is a crucial metric for understanding an individual's baseline energy expenditure. It quantifies the calories burned by the body while at complete rest, performing only essential life-sustaining functions. This calculation serves as a foundational element for determining total daily energy expenditure and subsequently, calorie targets for various health goals.
The Basal Metabolic Rate (BMR) calculator estimates the minimum calories required to sustain vital bodily functions at rest. It considers factors like age, gender, weight, and height. BMR represents the energy expended for breathing, circulation, cell production, and nutrient processing. This metric is fundamental for developing personalized dietary and exercise plans for weight management or muscle gain.
Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic life-sustaining functions while at rest
The Basal Metabolic Rate (BMR) is a crucial metric for understanding an individual's baseline energy expenditure. It quantifies the calories burned by the body while at complete rest, performing only essential life-sustaining functions. This calculation serves as a foundational element for determining total daily energy expenditure and subsequently, calorie targets for various health goals.
Variables: Weight in kg refers to your body weight in kilograms. Height in cm refers to your height in centimeters. Age in years refers to your current age in full years.
Worked Example: Calculate BMR for a 30-year-old male weighing 70 kg and standing 175 cm tall using the Mifflin-St Jeor equation. First, multiply 10 by 70 kg, then multiply 6.25 by 175 cm, then multiply 5 by 30 years. Then, add 700 and 1093.75, then subtract 150, then add 5. The BMR is 1648.75 calories.
This BMR calculator employs scientifically validated equations, primarily the Mifflin-St Jeor equation, which is widely recognized for its accuracy in estimating resting metabolic rate. It also offers the revised Harris-Benedict equation, another established standard in nutritional science. These methodologies are supported by research from institutions like the American Dietetic Association.

How BMR Calculation Works - Medical Methodology
Our BMR Calculation System uses Mifflin-St Jeor medical formulas to provide accurate metabolic assessments and calorie optimization insights. Here's the complete technical methodology:
Core BMR Formula (Mifflin-St Jeor): For men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5. For women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161. This calculates your Basal Metabolic Rate using the most accurate medical formula.
Imperial Conversion: For imperial units, weights and heights are converted to metric before calculation. Weight in pounds × 0.453592 = kg, height in inches × 2.54 = cm.
Activity Level Multipliers: Sedentary: BMR × 1.2, Lightly active: BMR × 1.375, Moderately active: BMR × 1.55, Very active: BMR × 1.725, Extra active: BMR × 1.9. These multipliers estimate total daily energy expenditure.
Weight Management Calculations: Weight loss: BMR × activity multiplier - 500 calories, Weight maintenance: BMR × activity multiplier, Muscle gain: BMR × activity multiplier + 300-500 calories.
AI Accuracy Enhancement: Our algorithms incorporate medical research data across different populations and metabolic conditions to provide context-aware health recommendations.
Metabolic Management Strategies
- Track consistently - regular BMR monitoring helps identify metabolic trends and patterns
- Consider body composition - muscle mass significantly impacts metabolic rate
- Focus on sustainable habits - gradual metabolic adaptation is more effective than drastic changes
- Combine with other metrics - use BMR alongside BMI, body fat percentage, and fitness levels
- Consult healthcare providers - for personalized metabolic guidance and medical conditions, seek professional advice
