I followed this diet very closely for 12 days and neither gained nor lost weight. I feel that people should be wary of this diet; apparently some people have lost weight on it, but some people will not. I have lost weight on restricted carbohydrate diets but thought I would give it a try. I think it can be dangerous for people who have blood sugar problems (as a lot of people apparently do) to consume the huge amounts of carbos found in fruit.
