I ran into someone yesterday who I hadn't seen in over a year and she did not recognize me until I started talking to her. She was amazed at how different I look. If you ever doubt that the single pound losses add up to make a difference, let me tell you that they do! I haven't lost particularly rapidly -- 95 pounds in 15 months averages out to a little over 6 pounds a month (not all that much for someone with as much to lose as I have) -- but it has made a big difference in my appearance and an even bigger difference in how I feel and what I am able to do.
