Amcal shakes

I'm trying out the Amcal 'Be good to yourself' shakes. Starting tomorrow I'm going to substitute my lunch for one of the shakes. I also got a handy little booklet that has different measurements for each protein and carb I should be having at each meal. I've gotten one of each flavor to see which is the best. I can also add fruit to them to make them nicer. The woman at the chemist said she had lost 10kgs since being on it, but didn't specify how long it had taken. I'm not going to bother with the bars as they don't look that appetizing. The weight watchers brand bars are pretty delicious, so I think I might keep getting them. Anyway I'll see how it goes, obviously a major part of any weightloss I have will be more to do with portion sizes of my meals than what the shakes will do, but they are high in protein which might be more beneficial for the amount if exercise I'm doing and what I want to achieve.
