If you've ever thought about using the ketogenic diet for cycling, you may want to listen in. We look at a pair of modern classic studies that compare traditional high carbohydrate diets to periodized low carb and keto. This includes a study with, and a study without a carbohydrate re-adaptation period.
Low carbohydrate, high fat diet impairs exercise economy and negates the performance benefit from intensified training in elite race walkers
Crisis of confidence averted: Impairment of exercise economy and performance in elite race walkers by ketogenic low carbohydrate, high fat (LCHF) diet is reproducible
One of the theorized benefits of low carb or ketogenic diets for cyclists is that it spares glycogen so it can be used when needed most. Kolie and Kyle walk through a paper investigating this question. They then discuss the upsides and downsides and potential utility of fat-adaptive diets in daily training.
Fat adaptation followed by carbohydrate loading compromises high-intensity sprint performance
