I know what you mean. I still feel as fat as I ever was, even though when I look at my old clothes I don't recognize how I could possibly have fit in to them.

There is this dissonance between mental body image, and the way we actual way we look. Even though we can look at our old clothes and see how much smaller we are now, we still feel just as fat as before. It has a lot to do with self esteem, I think. It's kind of how an anorexic can logically look at their clothes and measurements and see they are very small, but actually have a self image that is very fat.
