Slim fast does work but I wouldnt rely on it all the time b/c once your off it you'll gain everything back. Besdies do you really want to drink slimfast every single day? I would ge bored of it. Once in a whil I'll have a slim fast bar but thats only when im in a rush and I have no time 2 make my breakfast lunch or dinner so I just grab and go. If I had 2 take it every day (although they are diff. varieties) I would get sick of it.
