Celebrity Slim has anyone out there used this??

Yes. I am currently on this diet. I am only in my 3rd week though. In my first week, i lost 3.5 kilos. In my 2nd and 3rd week i lost 600 grams each time. The idea of this dit is to LEARN the healthy eating habits. You WILL put the weight back o nafter the diet if you go back to eating chips as snacks and large greasy hamburgers for dinner and stuff like that, but if you stick to the healthy eating and control your portion sizes, its good. The shakes are so easy, yo ujust add water and ice and shake it. That's it! No thinking about it. you have three small snacks between each meal and you have one balanced meal. It really works.

Yeah, I don't think those types of things are healthy either. It might make you lose weight right at first, but it will just come right back as soon as you go back to your old eating habits. It's better to take the weight off slowly through healthy eating and exercise! :)
