My brother is on a ketogenic diet.  It stresses the importance of low carbs and high fat.  Have you ever heard of it?
sure have, I've done it myself. it is really high fat, adequate protein, low carbohydrate.
Yes I tried it a few years ago, as well.  I still try to keep my white carbs in check so I don't have as many sugar cravings.  What other kinds of diets have you tried?

The classic therapeutic ketogenic diet was developed for treatment of paediatric epilepsy in the 1920s and was widely used into the next decade, but its popularity waned with the introduction of effective anticonvulsant medications.

There is tentative evidence that a ketogenic diet (high-fat, low-carbohydrate, adequate-protein) decreases the number of seizures and eliminate seizures in some; however, further research is necessary. It is a reasonable option in those who have epilepsy that is not improved with medications and for whom surgery is not an option. About 10% stay on the diet for a few years due to issues of effectiveness and tolerability. Side effects include stomach and intestinal problems in 30%, and
