Mathematical Formula & Scientific Methodology
Formula: Thermodynamic Energy Balance
Energy In = Energy Out (TDEE)Equates daily food metabolizable energy to metabolic heat and mechanical work expenditure.
Model Assumptions
- Constant body mass and glycogen store equilibrium
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| TDEE | Total Daily Energy Expenditure | kcal |
Scientific Limitations
- Daily variations in water balance can cause temporary scale fluctuations ±1-2 kg
