Macronutrient Calculation
Macronutrient amounts are calculated based on total daily calories and the desired percentage for each macronutrient:
Recommended Ratios
| Ratio (Carbs:Protein:Fat) | Description |
|---|---|
| 40:30:30 | Balanced, suitable for general health |
| 50:25:25 | High carb, ideal for active individuals |
| 45:20:35 | High fat, suitable for low-carb diets |
| 55:25:20 | Moderate carb, balanced for endurance |
These ratios align with the Dietary Guidelines for Americans 2020–2025 (45-65% carbs, 10-35% protein, 20-35% fat). Adjust based on your dietary goals, activity level, and health needs.
