Fat Adaptation and Carbohydrate Needs in Endurance Exercise

Marathon Handbook reported on a very-low-carbohydrate diet that promises better fat burning reduces reliance on carbohydrates during long endurance sessions. According to that report, improved fat access does not necessarily eliminate glucose's usefulness, especially when exercise is prolonged, moderately hard, and started with limited carbohydrate availability. The report said a randomized trial examined this question. No specific trial results, participant numbers, or dates were provided in the supplied report, so the current state of the evidence remains unclear from this coverage alone.
