Episode notes
Family Cholesterol Reversal Story
- Sam used family genetics to identify elevated cholesterol risk and prescribed specific foods and supplements.
- Within three months their LDL dropped 17–24% using targeted dietary changes and psyllium, garlic and oat bran.
Single-Gene Versus Polygenic Risks
- Some conditions are single-gene and high-impact while others are polygenic and probabilistic.
- Fitness Genes uses both single-gene flags and polygenic risk scores to triage health priorities.
ACTN3 Explains Power And Recovery
- ACTN3 (alpha-actinin-3) links strongly to power performance and muscle recovery differences.
- Lack of the protein increases muscle damage risk and necessitates longer recovery and targeted supplementation like creatine.
