Part 10/14:
French advocates a flexible, periodized approach to nutrition, aligning carbohydrate intake with training demands. High-intensity interval and resistance training deplete glycogen stores and benefit from carbohydrate fueling immediately before, during, and after sessions. Conversely, during lower-intensity or rest phases, a ketogenic approach—favoring fats and ketones—can enhance metabolic flexibility and efficiency. The key is understanding the body's fuel preferences at different intensities and adjusting diet and activity accordingly, rather than adhering strictly to one paradigm.
