Episode notes
Strict RFL: Protein-First Rapid Fat Loss
- The strict RFL is a food-based protein-sparing modified fast focused on maximal fat loss while preserving lean mass.
- It supplies high protein, essential fatty acids, and veggies while minimizing other carbs and fats to keep deficits huge and muscle spared.
Scale Protein By Lean Mass And Activity
- Scale protein to lean mass and activity: leaner people and those who resistance train need more protein.
- Use resistance training plus adequate protein to prevent muscle loss during aggressive deficits.
Use Strict RFL As A Short Kickstart
- Use strict RFL for short, intense kickstarts to build momentum and reprogram eating habits.
- Expect large weekly fat losses for high-body-fat individuals and use RFL transiently, not permanently.
