Has anyone tried the slimfast diet and what were the results?

Meal replacement: While in general i don't recommend meal replacement diets because they are very restrictive and hard to stay with, there are few that are really harmful. These like Slimfast work by restricting calorie intake. This can be done with anything but Slimfast etc tries to balance vitamins/proteins/calories to help with hunger and sugar fluctuations. Hard to do for extended period and maintain weight.
