Guide Complet pour Dépense Énergétique TDEE
La Dépense Énergétique Totale (TDEE) représente le nombre total de calories brûlées par jour en incluant l'activité physique.

Comment Fonctionne Dépense Énergétique TDEE
TDEE is comprised of several distinct energetic components: Basal Metabolic Rate (BMR), the Thermic Effect of Activity (TEA), the Thermic Effect of Food (TEF), and Non-Exercise Activity Thermogenesis (NEAT). We estimate it by multiplying BMR by an activity factor.
Analyse Mathématique et Formules
To find TDEE, we first calculate the Basal Metabolic Rate using standard formulas (like the Mifflin-St Jeor or Harris-Benedict equation) and scale it based on weekly physical exertion.
Multiply your base metabolism (BMR) by a factor ranging from 1.2 (sedentary) to 1.9 (highly active athlete).
Exemples Pratiques d'Application
Example 1: Moderate exercise program
- Calculated BMR: 1,600 calories
- Physical Activity: Exercises 3-5 days a week (Multiplier: 1.55)
- Calculate TDEE: 1,600 × 1.55 = 2,480 calories burned per day
Cas d'Utilisation Concrets
✦ Caloric Deficit for Fat Loss
Subtract 300 to 500 calories from your TDEE to design a sustainable and healthy weight loss plan.
✦ Caloric Surplus for Muscle Growth
Add 250 to 450 clean calories to your TDEE to support muscle recovery and lean mass growth.
✦ Maintaining Energy Equilibrium
Consume calories matching your TDEE to stabilize your body weight during maintenance phases.
⚠ Erreurs Courantes à Éviter
- Overestimating Physical Activity: Classifying oneself as 'highly active' based on light exercises, resulting in a high TDEE calculation and weight gain.
- Ignoring Metabolic Adaptation: BMR and TDEE decrease as body weight is lost; calculations must be updated regularly.
Foire Aux Questions (FAQ)
Q: How often should I recalculate my TDEE?
Every time your body weight changes by 3 to 5 kg, or your weekly physical activity level shifts.
Q: What is BMR?
Basal Metabolic Rate is the calories your body burns at rest to maintain vital life functions (breathing, organs).
