At one point, I lost 30 pounds (190-160) and could barely tell a difference in myself until I looked at my before and after side by side. Having the same clothes on and having the picture taken from the same angle helped. I know personally that I never know how heavy I look until I see a picture of myself. I kind of always saw myself in the mirror as that 160 pound girl, so when I actually was 160, it looked the same to me. In reality, the difference was very obvious.
(Unfortunately, I've gained up to 205, but I'm down almost 15 pounds already.)
You definitely WILL start to see a difference in your body as you continue to lose weight- sometimes it just takes a while for our brains to catch up with our bodies.
