Episode notes
Higher Carb Intake Raises Net Oxidation
- More carb intake can still raise net carb oxidation despite lower efficiency per gram.
- High carb feeding likely improves performance by lowering oxygen cost of running, akin to a 'super-shoe' effect.
Train Your Gut To Tolerate More Carbs
- Experiment to find the highest comfortable carbohydrate intake during training before racing.
- If you tolerate high intake, increasing from 90 g/h toward 120+ g/h can yield small but race-relevant gains.
Ozempic Raises Complex Doping Questions
- WADA is monitoring GLP-1 drugs (e.g., Ozempic) because they can cause rapid weight loss and may be abused.
- Mechanistically, appetite suppression makes performance benefit unclear since athletes need high energy intake to train and race.
