During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.
I’ve been there and have tried the Ketogenic Diet. It’s very difficult even though I am a very determined and goal oriented person. When I set my mind up to do something, I will normally achieve it because I am just so stubborn about personal goals that I don’t give up until I do! Yes, you will lose a lot of weight quickly, but I am not interested in giving up bread, pasta and birthday cake for the rest of my life.
