I did that diet in the 80's too, and lost the seventy pounds I had gained with my third pregnancy. There was definitely an upside to it, knowing that you couldn't eat ANY food made it simple. And the hunger was not too bad. I got pregnant again though, so can't help with the long term maintenance issue.

I will say though, that it occured to me I would have to start worrying about controlling my "real food" intake when I was done. But you know how that goes, you are sure you'll be able to do it....
