TDEE 計算機とは?
無料のオンライン TDEE 計算機。身長、体重、年齢、活動レベルに基づいて1日の総エネルギー消費量を計算。
Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including all activity. Knowing your TDEE is essential for weight management — eat below it to lose weight, above it to gain weight, and at maintenance to stay the same. TDEE Calculator uses the Mifflin-St Jeor equation to estimate your BMR, then multiplies by an activity factor to determine your TDEE.
Enter your age, gender, weight, and height. Choose between metric (kg/cm) or imperial (lbs/in) units. Select your activity level from five options: sedentary (desk job, little exercise), lightly active (1-2 days/week), moderately active (3-5 days/week), very active (6-7 days/week), or extremely active (twice daily or physical labor).
The calculator shows your BMR (the calories your body needs at complete rest) and your TDEE. Below the main result, calorie targets are displayed for five goals: maintenance (your TDEE), mild weight loss (TDEE - 250 calories, for ~0.5 lb/week loss), weight loss (TDEE - 500 calories, for ~1 lb/week loss), mild weight gain (TDEE + 250 calories), and weight gain (TDEE + 500 calories).
Each calorie target includes the estimated weekly weight change. The BMR result also shows a healthy BMI range for your height, contextualizing your weight relative to standard health guidelines. All calculations use the Mifflin-St Jeor equation, which is accurate within approximately 10% of measured BMR for most people.
