slimfast is based on the cutting calories to lose weight idea. If that works for you then great. It doesn't have any other magic secret to it.
I read in self magazine a while back that one slimfast meal bar has more sugar than a snickers. So if you're watching your sugar intake then its not a good idea. If you are just looking for a way to cut calories without having to put much thought into it and don't mind getting less protein and lots of sugar than go for it. Personally I'd rather eat food and if I wanted sugar I'd just eat a reecess fast break for 240 calories. I think slimfast is pretty low on fiber too. This is just what I know, its not intended as an argument. Just thought I'd share my opinion.
