Dr. Mark Madsen discusses the science behind intermittent fasting, ketosis, and their effects on health, aging, and brain function. He explores mechanisms like BDNF, autophagy, and evolutionary perspectives on stress responses.
Key Topics
- Mechanisms of fasting benefits: calorie restriction, glycation, inflammation
- Role of ketones as signaling molecules and energy sources
- BDNF and brain plasticity
- Exogenous ketones and athletic performance
- Evolutionary perspective on stress and adaptation
