Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Ketogenic athletes burn significantly more fat than carbohydrate-fueled athletes, providing a larger energy reserve for endurance.

◐Partially SupportedIt is possible to be fully ketogenic and fat-adapted outside of exercise and maintain equivalent performance, with the potential for better outcomes.

✕Not SupportedThe traditional exercise physiology view that prioritizes carbohydrates heavily over fat for performance may be outdated.

◐Partially SupportedSome strongman athletes can perform on a ketogenic diet due to enhanced fat oxidation and glucose replenishment.

✕Not SupportedCarbohydrates are not strictly necessary for performance during long, intense exercise.

◐Partially SupportedCurrent literature is disproving the traditional paradigm that carbohydrates are essential for all sports.
