2-3% improvement supposedly over 1 hour efforts. Team Sky and Farah are both supposedly big proponents. Just hype or is there any validity to this?

Abstract
Everyone is seeking nutritional strategies that might benefit performance. One approach receiving much attention is ketones, or ketosis. Ketones are very simple compounds made of hydrogen, carbon, and oxygen, and ketosis is a metabolic state whereby the body uses predominantly ketones. Ketosis can be achieved by fasting for longer than 72 hours or by following a very lowcarbohydrate, high-fat diet (ketogenic diet) for several days to weeks. Alternatively, ketone supplements purportedly induce ketosis rapidly and do not require strict adherence to any specific type of diet; however, much of the touted benefits are anecdotal. A potential role for ketosis as a performance enhancer was first introduced in 1983 with the idea that chronic ketosis without caloric restriction could preserve submaximal exercise capability by sparing glycogen or conserving the limited carbohydrate stores. Few human studies on the effects of a ketogenic diet on performance have yielded positive results, and most studies have yielded equivocal or null results, and a few negative results.
Wow. Quite the answer. Thanks for taking the time to explain. EOT/

It probably works well when combined with the high dose corticosteroid injections and asthma medications that they are using ...
As someone who lives and trains in ketosis most of the time for the last three years, I personally feel that while ketosis is healthier and beneficial overall, it doesn't give noticeable performance benefits or detriment for efforts of under two hours (definitely does for longer ones), excpet maybe for my overall work capacity and recovery. Maybe added ketones might be an immediate performance bump for someone who is not fat-adapted, but I have no interest in such a high-priced artificial product until maybe I start hearing consistent favorable testimony. I am among those who refuses to pay $250 for the VF4% either, it just wouldn't be worth it for me personally.
