I started it.. then ditched it after some reading.
I started on a whim thinking if everyone else was doing it...
However there are some things the bug me. True you can loose weight on this. However the fact is that it comes right back (very quickly) if you get off the diet.
It seems that it is good for a quick fix. However, knowing that watching your intake of fats and sugars along with moderate excercise will win in the long run with less health "questions" as from major nutritionists, I personally err on the side of caution.
I think some explinations from these to links helped me...

If you can do it, try weight watchers or some slower long term solutions. These ALL involve restricting your intake in one form or the other, however it seems to me that the fallout when you stray from the plan is less dramatic with some other diet models. This is all my opinion from what I have read, I have attempted both, and since both involve restriction, I chose the one that seemed to have the better longer term health implications.
