Calculateur de calories
Total Daily Energy Expenditure (TDEE) is the number of calories your body burns in a day — and knowing it is the foundation of any diet plan that actually works. Eat below TDEE to lose weight, above it to gain muscle, or match it to maintain. Our calorie calculator uses the Mifflin-St Jeor equation (the most validated formula in clinical nutrition) combined with your activity level to estimate TDEE. You also see the calorie targets for common goals: fat loss, maintenance, lean bulk.

Comment l'utiliser
- Enter your age, gender, height and weight.
- Select your activity level (sedentary through very active).

- Choose a goal — lose weight, maintain, or build muscle — to see the recommended calorie intake.
Formule et méthodologie
Mifflin-St Jeor BMR: Men = (10 × kg) + (6.25 × cm) − (5 × age) + 5. Women = (10 × kg) + (6.25 × cm) − (5 × age) − 161. TDEE = BMR × Activity multiplier (1.2–1.9).
Cas d'usage courants
- Setting a calorie deficit for sustainable fat loss (typically −500 kcal/day = −1 lb/week)
- Calculating how much to eat in a lean-bulk phase
- Understanding why your current diet is or isn't working
- Adjusting calories after a weight change
- Comparing BMR between two activity levels
