I started SW just over a week ago as my cholestral levels were high and I've already lost 5IB!! I already had the books as I've done SW before. Its the best for me at least. You have Green days meaning you can eat as much rice,beans,cheese,pasta,eggs,the list is endless. Then the Red days where you eat as much meat even a whole chicken as long as the skins taken off,fish not oily,all veg is "Free" on both R+G days. Mullerlight or any low fat yogurts are also Free. You also have 15 "Syns" that means you can have a pack of crisps,4 jaffa cakes,small choc bar.
