I started the ketogenic diet in the first week of February.  I have just gone off it, having lost fifty pounds.  I found myself eating two meals a day and not feeling hungry, living on meat, fish, cheeses, eggs, mushrooms, greens (including avocados).  My wife and I found specialty foods like monk sugar and tofu noodles that helped broaden the tastes and textures in our diet, although any kind of low-carb bread turned out to be disappointing.

I started the diet after researching as best as a layman can, and having heard from my elder brother, who was always overweight since infancy, that he had lost 100 pounds and ceased to be diabetic in a little over a year.

I can't say it's for everyone, but it has worked for him and for my wife and me.
