Yes, I was thinking of SP too. Maybe it would work best for you, WhoKnows
You eat 50% of your plate foods marked with an S, and 50% foods marked with a P (no "free" food unless it has one of these symbols - so no potatoes/rice/pasta/bananas; no yoghurts but you can have quark or cottage cheese). You still get your HEA for milk/cheese and you can have two HEBs (for your fibre) so you could have up to six slices of wholemeal bread, if you go for the Kingsmill crustless. And of course you get your 5 - 15 syns a day on top.
I am totally craving a double decker. I have been craving a double decker since last Thursday and I don't know why. I have tried substituting lower-syn chocolate (hifi bars, kit kats) but I am still craving a bloody double decker. If I lose 1.5 lbs on Thursday and get my 3 1/2 stone award, I will treat myself to one for lunch
