Total Daily Energy Expenditure (TDEE) is the sum of calories you burn each day.
| Component | What it is | Typical share |
|---|---|---|
| RMR/BMR | Resting energy | 60%–75% |
| TEF | Energy to digest food | ~10% |
| EAT | Planned exercise | 0%–20% |
| NEAT | All other movement | 10%–30% |
TDEE ≈ RMR + TEF + EAT + NEAT. If RMR is 1,600, TEF 160, EAT 300, NEAT 400, TDEE ≈ 2,460 kcal/day.
Resting Metabolic Rate (RMR) is the energy burned at rest while awake in a relaxed state.
Basal Metabolic Rate (BMR) is the energy your body uses at rest to run core functions.
Non-Exercise Activity Thermogenesis (NEAT) is energy from daily movement outside planned workouts.
Active Calories are calories burned above resting during movement and exercise.
