Episode notes
Keto Origins and Mechanism
- The ketogenic diet originated as a treatment for epilepsy.
- It works by restricting carbohydrates, forcing the body to burn fat and produce ketones, which can fuel the brain.
Ketones as Brain Fuel
- Ketones provide an alternative fuel source for the brain during carbohydrate restriction.
- This is important because the brain primarily uses glucose and cannot directly use fat.
Keto vs. Other Low-Carb Diets
- Keto differs from other low-carb diets like Atkins or paleo due to its strict carbohydrate restriction.
- High protein intake, like in Atkins, can inhibit ketosis by triggering an insulin response.
