I have to get my few cents worth in here, too. I have lost 60 pounds over the past 10 months and the difference is especially noticeable. I work on a campus, but in a trades building where I am the only female. You can just imagine the comments.
I get comments from, have you lost weight, to you're so hot. Really now! ...I'm 50. Anyway, I just smile and say thank you and feed off of that for encouragement. I also have many friends who told me to stop losing weight 20 pounds ago because I look just fine to them now. However, I still have a goal in mind to be at 120 pounds (that's another 6 pounds) and I plan to do that for me, whether the other people think I have lost enough, or not.
If I find that I am starting to sabatoge my efforts, I come to this list. Nobody here can see me, so they have no idea if I look nice today, or not. They just have to believe what I am telling them.
So for that, I get the actual encouragement to stay on program and not worry about how I look today.
Beware, though, of people who try to sabotage your efforts. Sometimes people don't realize that they are doing it, but tend to tempt you for some hidden reason...mostly jealousy. Acknowledge those situations and have a plan, in advance, of how you will handle those times. You won't always be able to resist the temptations, but I find that if I have a plan, I don't do as much damage to my weight loss as when I don't have a plan.
I wish you the best of luck in your efforts. But most of all, lose the weight to be a healthier you. It's about you and for you.
Take care,
