well lucylis i lost 19lbs in 3 wks, it is very hard, its very anti social as well.a friend of mine was on it for 3 months and lost 4 stone, i dont know how she did it that long.i put half a stone back on when i came off it, shes put a bit on as well over the last year but not too bad. there have been other people i know that have been on it, lost a pile and put it all back on again. the plus side of it is that it kinda sucks you in, so ur toning while ur on it, ul lose inches. when you come off it, unless ur in the frame of mind to keep losing weight, it will go back on very quickly. i like the strawberry and choc shakes, vanilla a bit bland, i didnt get the soup cos im not a big lover of soup, i tried a flapjack but thought it was horrible. make sure you get the fibre powder with it and drink 2 litres minimun of water. good luck with it and keep us posted
