Metabolic Flexibility Basics
- Metabolic flexibility is your body's ability to efficiently use carbs and fats as fuel and switch between them.
- Optimizing flexibility can improve health, body composition, and exercise performance.
Fuel Choice by Activity Intensity
- Use carbs for high intensity and performance activities like lifting or sprints.
- Rely on fat for low intensity activities and improve fat burning to ease fat loss.
Ketogenic Diet Impairs Carb Metabolism
- Chronic ketogenic diets downregulate carbohydrate metabolism enzymes like PDH.
- This reduces high-end carbohydrate metabolism and performance by about 8-10%.
