Is there any validity to the truth claims made about keto diets helping with mental illness? I listened to a podcast which featured a psychiatrist who champions keto and uses it with his patients who have treatment resistant depression and several other diseases and claims to have dramatic success. He sounded quacky to me, used a lot of catch phrases over and over and really just seemed to have a surface understanding of what he was talking about. Anyway, is this supported by any evidence or is my suspicion correct that this is quackery?
Thanks
