You will see greater endurance adaptations in response to exercise in the short term on a ketogenic diet, though this effect decreases the longer you maintain the diet. The downside to a ketogenic diet is your total training volume for work above the lactate threshold is more limited. As a result, high level athletes tend to spend the majority of their time consuming a carb-rich diet, then switch to a ketogenic diet for 2-3 weeks prior to competition. During this low carb period, they just focus on a very high volume of low/moderate intensity work. Finally, 2-3 days before competition, they will carb-load to glycogen super-compensate, getting the best of both worlds.
