Episode notes
Metabolism Is Mitochondrial Energy Conversion
- Metabolism is mitochondrial electron flow converting food into ATP, controlled by thyroid signalling.
- Poor food quality or low calories impairs ATP production and shifts energy into fat or fatigue via thyroid downregulation.
Fast Digesting Preworkout Smoothie For Surfing
- For active mornings eat a quick digesting pre-surf smoothie: raw milk, grass-fed whey, salt, blueberries and honey.
- Follow with a larger post-session meal of ground beef and fruit to replenish without heavy stomach load.
Carnivore Diet Resolved My Severe Eczema
- Paul cured severe eczema by trying a strict carnivore diet and saw dramatic improvement within weeks.
- He later reintroduced fruit and honey to an animal-based approach because long-term keto caused palpitations and low testosterone for him.
