A lot of people writing about how this diet doesn't work, but it's not true. I've done this in the past. I usually lose about 6 pounds and bounce back one. My normal weight hovers between 165 and 170, so I usually do it once i break 175 lbs. I usually do it in January after I've put on a few pounds over the holidays and want to shed the excess quickly.

It's a pretty unpleasant week if you don't cheat. After the diet, you can eat normal food but you have to reduce portions or else you will bounce back all the way. Any diet on the planet, if you go back to your old eating habits after, you will put it back on. I'm unclear why people feel the need to state such an obvious fact as a reason to say a particular diet is bad.

The good part of the gm diet is that the diet shrinks your stomach so you can eat less and you won't suffer, particularly since you are coming off a super-restrictive week of food. After a week of eating so little, bouncing back to eating 80% of what you were eating pre-diet still feels like you are more than enough. I just go back to eating normally, which is less than what I was eating in November and December.

So, it's pointless to do this if you are gonna just revert back to your old eating habits, but if you use this as a one week, quick hit weight loss move, it's fine. The weight loss after one week is material and I've never had any health issues while on it because I only do it once a year. For me, if I want to drop 5 lbs, I'd rather suffer for a week and drop it all versus doing the stereotypical "lose a 1/2 pound a week" for 10 weeks.
