Weight Loss Calorie Calculator
Calculate exact daily calories required to achieve your target weight loss rate
Maintenance TDEE: 2500 kcal/day
Mathematical Formula & Scientific Methodology
Formula: Wishnofsky Adipose Energy Constant
Daily Deficit = (Weekly Loss kg × 7700 kcal) / 7Applies the classical Wishnofsky caloric deficit formula adapted with modern metabolic safety thresholds.
Model Assumptions
- Loss consists predominantly of adipose tissue with preserved lean mass
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| 7700 | Approximate energy density of 1 kg human adipose tissue | kcal/kg |
Scientific Limitations
- Adaptive thermogenesis can cause energy expenditure to drop slightly as weight decreases
