Strategic carbohydrate feeding improves performance in ketogenic trained athletes.
Clinical nutrition (Edinburgh, Scotland)·August 1, 2025·PMID 40614653
Why it mattersChronically ketogenic athletes often avoid carbohydrates, yet pre-exercise carbohydrate ingestion may provide an immediate performance edge without disrupting long-term adaptation. This study clarifies that the benefit is timing-dependent, informing practical fueling strategies for athletes who wish to maintain ketosis while optimizing race-day performance.
