Nobody is saying much to me about my weight loss either, but I suspect it's because people are embarrassed to talk about weight, especially to a woman. Like saying "you look like you've lost weight" would carry an implicit message of "Boy, were you ever fat." And what if they were wrong about the weight loss? That would be awkward.

I have noticed people saying "You look good..." while eyeing me as if they were trying to figure out what to say. One woman said "You look happy, like you've been taking care of yourself" and when I told her I had lost weight, she looked incredibly relieved, like it was OK for her to talk about it because I had mentioned it first.
