Kathryn - Having met you I didn't think you were "big" . Finding your own healthy weight is the wtg I think - It may be different from what a book says.
When I was young I was mostly 7st (almost 45k). On the way back from guardia I got to that 7st point relatively quickly once the bug was out of my system and stayed at 7st for years. Mostly just on sugar free for hypoglycemia which was bad then too.. I forget - may have been no white flour as well. I prefer the 50 -52K zone because I have there is room for fluctuation without it getting serious if I lose a few with some bug.
Just been playing with the converion calculator - K = st. Interesting.
Does anyone have any suggestions for talking to someone morbidly obese, and still gaining. My dd and I both have (different) people in our lives who use the "you wouldn't understand" line and don't see it as a problem. The one I know has trouble moving. (dx chronic fatigue) but if I tried to move that much weight about I don't think I could do it either. DD's friend want to go O/S with her and dd is thinking no way.
