How the Calculator Works
Scientific Formulas Used
- BMR Calculation: Uses Mifflin-St. Jeor equation - the gold standard for metabolic rate estimation
- TDEE Formula: Multiplies BMR by activity factor (1.2 to 1.9) for total daily energy
- Macro Distribution: Allocates protein (25-35%), carbs (40-50%), fats (20-30%) based on goals
- Calorie Adjustment: Creates deficit/surplus of 300-500 calories for safe weight change
Goal-Based Recommendations
- Fat Loss: 15-20% calorie deficit with higher protein to preserve muscle mass
- Maintenance: Calories match TDEE exactly - ideal for body recomposition
- Muscle Gain: 10-15% surplus with emphasis on post-workout nutrition timing
- Custom Plans: Fine-tune macros manually for specialized dietary needs

Fitness Strategies & Health Tips
Remember: Consistency Beats Perfection
Sustainable progress comes from small daily habits, not extreme measures. Use this calculator as your guide to make informed decisions.
Nutrition Fundamentals

Recovery & Wellness
