Episode notes
Genetics As A Performance Blueprint
- Genetics creates a physiological avatar that reveals strengths and weaknesses for performance planning.
- Knowing genetic predispositions narrows focus and increases clarity for training and recovery.
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.
