Episode notes
Practical Protein Limits
- Limit daily protein to about 0.8–1.5 g/kg and avoid extremes promoted online.
- Prefer plant-based proteins and reasonable amounts rather than 1 g per pound fads.
Weighted Vests Are Not Magic
- Don't buy a weighted vest expecting unique bone or core miracles; resistance training offers similar benefits.
- Introduce any extra load gradually to avoid back, knee, or tendon injury.
Skepticism About Collagen Claims
- Don't rely on collagen supplements for skin, hair, nails, or joints; randomized placebo trials are lacking.
- Treat anecdotal claims skeptically until rigorous trial data appear.
