Episode notes
Fat Can Fuel High-Intensity Workloads
- The body can adapt to burn fat at high exercise intensities previously thought to require carbs.
- Muscle glycogen is not obligatorily required for high-intensity performance when fat oxidation is upregulated.
Noakes' Personal Diet Reversal And Fallout
- Tim Noakes described converting to a low-carb diet in 2010 after reading clinical work, which reversed his type 2 diabetes.
- He then faced funding loss and legal battles before being vindicated in 2018.
Blood Glucose Is The Critical Limiter
- Blood glucose, not muscle glycogen, often limits exercise performance because the brain requires stable glucose.
- Carbohydrate intake during exercise mainly prevents hypoglycemia, not because muscle glycogen is absolutely essential.
