Dom talks about why there is a lack of studies for Keto and other ailments that it may be helpful for. Originally it was just used medically for epilepsy and the control of seizures and there is numerous research showing the efficacy is better than any drug without the side effects. The problem is it's very hard to do control studies with Keto and the nutrition science in general is way behind what current research is coming out with. Basically the food pyramid is completely wrong and how people view fats. It's not for everyone and some people tolerate carbs ok, but he said it's especially useful for people with deficits as it improved brain metabolism and a host of other functions.

This isn't some fad diet. I get why you might be skeptical and it's important that research be done and is being done currently. Figuring out the optimal macros(fat/carbs/protein) ratio and what the exact levels of ketones in the blood should be for a particular person is areas needed more research. People need to monitor their cholesterol #'s if they take on this diet but all in all, there isn't any downside I see to trying to see if it helps symptoms
