I think a lot of people who use the shake diets find it difficult to begin healthy eating habits once they begin adding proper meals, whereas diets like weight watchers you start from day 1 changing your eating habits so there is no real change throughout the diet. This becomes less of a diet because you pretty much jsut stay eating the same things. I hope all that makes sense. I know a lot of people who have not put their weight back on using diets such as weight watchers but almost everyone I know, including myself have put the weight back on after using milkshake diets. I did just have baby 4 months agao though.

For me though, as soon as I stop breastfeeding I will be back on the shake diet. I use Optifast. And it works really well for me.
