Hi J.,
So funny, I just posted this same question last week. I did go ahead and sign up. I'm on day 3 and have lost 3 lbs. It is definitely NOT a way to eat for life but I'm really enjoying it and I feel great. It isn't a really expensive way of eating as far as what kind of food you have to buy. I did a lot of research before I finally gave in and found a lot of good reviews. For me this is a good jumpstart and I am so excited and motivated.
Basically it is like this:
You pick 40 of the foods you like off the list in their Diet Generator....foods like specific types of fruit, chicken, fish, shrimp, green veges....etc. The diet generator then makes up a menu for 11 days that you have to stay true to. Also the website encourages a 30 minute brisk walk in the morning AND in the evening and drinking LOTS of water. The main idea is that it is "jacking" with you metabolism so your body is just trying to catch up. We tend to eat the basic same thing everyday so our bodies only set up to metabolize our normal way of eating. This way of eating speeds up the metabolism and burns fat at a higher rate. So far I do not see this as a "fad" diet since I'm eating a lot of fruit, veges, and high protein type food. After being on this for 11 days, you get 3 days of "cheat" days so you can have a reasonable amount of what you want for 3 days and then go back to your website, log in, and the generator prints out another 11 days of menus.
I really like it so far. I have about 35 pounds to lose and it is encouraging to see and feel it literally dropping off. After this jump start I will probably go with weight watchers.
I will warn you that this isn't really easy as some of your meals include a piece of halibut and walnuts. That's it. But you get to eat 4 times a day. If you want the first couple of days menu, email me and I'll share it with you.
Good luck, I know this weight loss thing can be frustrating. I'm turning 40 this year and 40 is going "down" sister. I'm going to be looking good when I blow out those 40 candles in August : )
