無料のオンライン カロリー計算機。基礎代謝率、1日の総エネルギー消費量、1日のカロリー必要量を計算。
Understanding your daily calorie needs is the foundation of effective weight management, whether your goal is weight loss, maintenance, or muscle gain. Calorie Calculator uses the Mifflin-St Jeor equation — one of the most accurate BMR formulas — to calculate your Basal Metabolic Rate, Total Daily Energy Expenditure, and recommended calorie intake for your specific goal.
Enter your age, gender, height, and weight. Select your activity level from six options: sedentary (little or no exercise), lightly active (1-3 days/week), moderately active (3-5 days/week), very active (6-7 days/week), extremely active (twice daily), or professional athlete. Each activity level applies a multiplier to your BMR to estimate your TDEE — the total calories your body burns per day.
Select your goal: lose weight (creates a calorie deficit of approximately 500 calories/day for about 1 lb/week loss), maintain weight (matches your TDEE exactly), or gain muscle (creates a surplus of approximately 300-500 calories/day). The calculator shows your goal calorie target alongside your BMR and TDEE.
The macronutrient breakdown recommends grams of protein, carbohydrates, and fat based on your goal calories. Standard recommendations: protein 25-30% (for muscle preservation), carbs 45-55% (for energy), and fat 20-30% (for hormone function). BMI calculation and healthy weight range are also displayed for additional context.
