Episode notes
Use Plant-Based Meats As A Transition
- Try swapping red meat for plant-based meat alternatives as a practical step to reduce red meat intake.
- Christopher Gardner's SWAP-MEAT trial showed lower LDL, TMAO, and modest weight loss on plant-based meat versus red meat.
How Much Protein To Target
- Aim for 0.8–1.2 g/kg/day of protein for general health, and up to ~1.6 g/kg for muscle-building or recovery.
- Increase protein only when needed; most benefits top out around 1.6 g/kg.
Dose, Type, And Cooking Matter
- Risk from meat depends on type, amount, and cooking method; processed and charred meats carry higher risk.
- Marinades with antioxidants (lemon, herbs) markedly reduce harmful compounds from high-heat cooking.
