Does a Low-Carbohydrate Diet Impede Endurance Sports Performance?
The American Journal of Clinical Nutrition’s Great Debates series pits two leading experts against each other on whether low‑carbohydrate, high‑fat (ketogenic) diets hinder endurance performance. Louise Burke argues that carbs deliver more oxygen‑efficient energy, so strict carb restriction can slow athletes during high‑intensity efforts. Timothy Noakes counters that after a 4‑6‑week adaptation, low‑carb athletes can oxidize fat at high rates and perform on par with high‑carb peers. Both agree that ingesting carbs during prolonged exercise improves outcomes, but the debate highlights gaps in understanding fuel utilization at elite levels.
