My wife wanted to do it, so I did it for 1 month, she did it for two. Recommending that one shouldn't exercise is asinine. Did I lose weight, of course. Transitioning back to real life is not easy and staying on that diet is not possible, at least for me. The real kicker is that my wife literally started losing her hair, so she stopped, and it took her almost a year to get it back. After some digging she found out she's not alone, but the people behind the diet to to great lengths to hide anything negative.
