Scientific Principles & Muscle Preservation Protocol
1. High Protein Retention Threshold

During caloric deficit, muscle protein synthesis drops while amino acid oxidation rises. Keeping protein at 2.2g/kg (1g/lb) protects lean mass against catabolic breakdown.

2. Adaptive Thermogenesis & Plateau Protocol

If scale weight stagnates for more than 14 consecutive days, decrement daily intake by 100–150 kcal exclusively from carbohydrate or fat allocations while holding protein steady.
