Are you by chance still wearing old clothes that don't show the loss? I know on days that I wear my old clothes (always kept them in hopes I would return one day, and I am woohoo ) that fit more snug, people actually notice, but with baggier clothes (really trying to hold out on buying clothes as I keep going down pretty steadily) no one says a thing. But it may help I work in an environment with a lot of nurses, doctors, and health minded people, so they encourage getting healthier, if that makes sense. Like LovetheNewMe said, they may be jealous or just not know how or what to say. I have one person who is always complementing me, but at the same time, says she is afraid that she does not want to offend me in the same conversation. Like people don't want to make you feel bad about what you used to look like I suppose is what she means.
