You look great! I lost weight too- mostly from surgeries that corrected a problem. However- I just made an effort to watch my sugar intake, and kept an eye on fat.
With some things I did want, instead of opening a bag of pototoe chips, I put a handful on a paper towel. Those types of things can be addictive and mindless eating. Between the surgery, and this- I went from a size 10 to a size 6..
