giula that makes two of us. I lost 2 stone a couple of years ago. I have a before picture. The after picture shows me looking smaller but no thinner, a bit like I have been through the washing machine and shrunk all over.
However I am not complaining and enjoying all the benefits. Consistently lower blood pressure, no indigestion, or very little, no aching knee, I can bend over to tie a shoe lace without holding my breath.
Actually, watermeadow I had the same problem. I lost 2 stone in 4 months. One person did say that I was looking well, but that was all. 
Gabriella I think people define themselves by clothes size, because if someone says they are 5ft 7 and weigh 11stone, or 5ft and weigh 10 stone, for an example, unless you see a photo it is not always easy to work out whether that is fat or thin, healthy or unhealthy, but if someone says I take a size 8/10/20, it is much easy to understand.
