I have also noticed that my comments are not required or listened to seriously about anything to do with beauty or diet. I don't really care, as at 43 I don't need to impress anyone.. but I've definitely noticed it in passing.
I also have noticed that people are not as friendly as they were when I was say, 20 pounds lighter than I now am (which I was for many years). I would have been just on the cusp of overweight/obese at the time, which I think makes a lot of difference in appearance compared to now. I wasn't living in the same city as I now am, but I really am not so sure that the changes are to do with geography... I really think it might have something to do with appearance too. People I meet are friendly, but coolly so these days. Oh well, their loss. I'm a super-fun, smart and cool person to hang out with!!
