Having said that, its not very palatable for very long. I was able to do it because I was a stubborn SOB who didn't mind pain and discomfort (6 sets of heavy squats made the diet seem like a piece of cake).
After your weight loss, I would "back off" on the diet and go on a maintenance type of diet that wasn't ketogenic. Get into the habit of exercizing every day, even if its just walking.
While I dont think the diet is as "dangerous" as its detractors say, I still have some misgivings about it, as a long term diet.
Did someone say cake? I don't think that's allowed. (smile)
