Example Output

## Your Daily Calorie Calculation ### 1. Basal Metabolic Rate (BMR) **Harris-Benedict Formula:** 1,472 calories/day **Mifflin-St Jeor Formula:** 1,456 calories/day **Average BMR:** 1,464 calories/day ### 2. Total Daily Energy Expenditure (TDEE) With moderate activity (3-4 workouts/week): 1,464 × 1.55 = **2,269 calories/day** ### 3. Recommended Daily Intake For 1-2 pounds weight loss per week: **1,769 calories/day** (500-calorie deficit) ### 4. Macronutrient Breakdown - **Protein:** 133g (30%) - supports muscle preservation - **Carbohydrates:** 177g (40%) - energy for workouts - **Fats:** 59g (30%) - hormone production and satiety ### 5. Additional Recommendations - Track your weight weekly, not daily - Eat protein at each meal - Time carbs around workouts - Stay hydrated (8-10 glasses water daily) ### 6. Important Considerations Adjust calories up by 100-200 if you feel fatigued or lose weight too quickly. Re-calculate every 10-15 pounds lost.
