Comparaisons
BMR vs. TDEE
Compare BMR and TDEE side by side. When to use each, key differences, and a clear verdict.
BMR
Taux métabolique de base — calories brûlées au repos par votre corps.
Essayer la première calculatrice →TDEE
Dépense énergétique quotidienne totale selon le niveau d'activité.
Essayer la deuxième calculatrice →Quand utiliser BMR
Use BMR when you want the absolute floor: calories your body burns lying still all day. Useful for medical calculations and fasting protocols.
Quand utiliser TDEE
Use TDEE (Total Daily Energy Expenditure) for real-world diet planning. It accounts for your activity level — which is what determines actual daily burn.
Side-by-side comparison
| Caractéristique | BMR | TDEE |
|---|---|---|
| Includes activity | No (rest only) | Yes (5 activity multipliers) |
| Output | kcal/day at rest | kcal/day with your lifestyle |
| Best for | Medical baselines, fasting | Weight loss, weight gain, maintenance |
| Typical values (adult) | 1,400 – 1,800 kcal | 1,800 – 3,000 kcal |
| Mifflin-St Jeor used? | Yes (base formula) | Yes (multiplied by activity factor) |
Le verdict
TDEE = BMR × activity factor. For diet planning, TDEE is what matters. BMR is the building block. If someone says "eat 2,000 kcal," they mean TDEE.

IMC vs. BMR
Use both: BMI to classify your current state, then BMR (or TDEE) to plan how to change it. BMI tells you WHERE you are; BMR tells you the BASELINE you start from.

BMI is the gateway metric — start there. If BMI says "overweight" but you have visible muscle, use body-fat percentage to confirm. If body-fat is healthy, BMI was a false positive.
