Indeed, changing habits in general seems to be a better approach than any 'fast' tricks. That said, Could there be at least some benefit to the fast diet in that you get to experience what it's like to have lost (significant) weight? It seems to be a common experience with addictions of various kinds that merely having had the (recent) experience of 'being clean' can be a great motivator to do it again or try and maintain it, because part of the problem is not remembering what things were like pre-addiction. It's not a magical solution, but it helps. From my own experiences with bouts of depression, simply experiencing joy again, even briefly, would make me remember what it was like pre-depression, and would often be a first step towards 'recovery'.
