Episode notes
Widespread Metabolic Inflexibility
- Many Americans are metabolically inflexible and cannot quickly switch from burning glucose to burning fat.
- This inflexibility causes crashes, headaches, weakness, and 'hangry' feelings when meals are skipped.
Incremental Fasting Progression
- Extend your breakfast by one hour each week instead of jumping to long fasts.
- Use small snacks like a handful of nuts or a teaspoon of MCT oil to bridge tougher steps.
Ketones Drive Fasting Benefits
- The key goal of fasting is extending ketone production time because ketones trigger mitochondrial repair and uncoupling.
- Coffee and tea without sweeteners support focus and polyphenols and do not break a fast.
