Does SlimFast actually DO anything?

[tactum]

as in, does the product itself do anything to help you lose weight or is it just a calorie management tool? Not quite sure how to explain it better!
If it just restricts calories by replacing 2 meals with the drinks then surely its no more use than a calories controlled diet?
Apologies for stating the bleeding obvious (if indeed I have!)

It's just calorie restriction, but contains vitamins.

It is high in protein too so keeps you fuller longer.

It just helps you restrict calories, there’s no magical weight loss ingredient (although my dh seems to this there is 🙄). It’s really high in sugar too so, particularly at breaskfast time you can actually consume less calories by eating a normal breakfast!
