Thanks for all your advise, as it happens in preperation for this diet, I put together my own weekly menu, listing everything I was allowed in one day right down to weights and measures (I used to be an analyst!). So I am sure I didn't go wrong (as I have become a label gazer) - it was the eating out that did it. We are both in senior management poitions and work quite long hours so often don't get home in time for dinner - soe eat out. I am finding it a little embarrassing eating in restaurants when I have to be so fussy about what they can and can't leave in. However I do take a packed lunch everyday which has helped a lot. I have now lost 13lbs, so nealy at my first target....
The hardest thing was when we both gave up being vegetarians after 10 yrs! There is only so much cheese one can eat..
