Calorie Calculator
Calculate daily calorie requirements tailored for weight loss, maintenance, or muscle gain
Maintenance baseline: 2678 kcal/day
Mathematical Formula & Scientific Methodology
Formula: Goal-Adjusted Energy Intake
Target = TDEE ± Goal Deficit / SurplusApplies caloric deficits or surpluses tailored to physiological rate of tissue synthesis or catabolism.
Model Assumptions
- Steady-state caloric tracking
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| TDEE | Total Daily Energy Expenditure | dimensionless |
Scientific Limitations
- Metabolic adaptation can decrease TDEE over consecutive weeks of deficit

A new predictive equation for resting energy expenditure in healthy individuals (1990)
Mifflin MD, St Jeor ST, Hill LA, Scott BJ, Daugherty SA, Koh YO (1990) — The American Journal of Clinical Nutrition, 51(2), 241-247
Key Finding: Mifflin-St Jeor equation is accurate within ±10% of measured REE in non-obese and obese individuals, recommended by the Academy of Nutrition and Dietetics as the most reliable standard equation.
