I'd have to agree with you, PF, except that anti-seizure drugs can have some pretty serious proven side effects and according to some of those links you posted it appears that diet may be more effective than drugs in treating the more severe types of seizures. Side effects of some common anti-seizure drugs:

In addition, I have to question the "slower growth rate" claimed as a possible effect of a ketogenic diet. Even if true, is this necessarily bad? I wouldn't be surprised that children who consume the SAD, filled with refined sugar and starches DO grow faster than children on a ketogenic diet. After all, high blood glucose stimulates release of insulin, which stimulates HGH... but couldn't this also be behind increasing rates of childhood cancers and other problems? Is a faster growth rate really desirable?
