Age Adjustments
| Age Group | Adjustment | Reason |
|---|---|---|
| 18-29 years | Standard calculation | Peak muscle building phase |

Goal-Specific Modifications
Weight Loss (Fat Burning):
- Use "Very Active" calculation even if less active
- Higher protein preserves muscle during caloric deficit
- Increases satiety and metabolic rate
Muscle Building (Bulking):
- Use highest range for your activity level
- Consider 2.0-2.4g per kg for maximum growth
- Combine with resistance training program
Maintenance (General Health):
- Use standard calculation for activity level
- Focus on protein quality over quantity
- Consistent daily intake more important than peak amounts
