No, it does not frown unless their preferences are not mainstream. That is a man who likes fat women would be more criticized than a man who likes sports illustrated women. At least by other men. XD

Of course, the problem with you saying “I don’t like fat women” is that transmits a lack of awareness and that what you value of women is how they look. While many of us know that is the case, and that many men only value our look, many want partners who value other things about us. So the problem is not that you have a preference, but that you are offering an image of yourself as superficial which is an undesirable trait for many people. Regardless, there would be women who won’t have a problem with that since the thing they are most proud of is their looks…

Usually in polite society, those comments are better to keep to yourself in the same way that if a woman said “I don’t like poor men” or “I only like rich men” she would be considered a gold-digger and “the worst”.

What you fail to see is that people who comment on other people’s looks, self identify as superficial. So you can comment on someone’s weight. But you have to accept that maybe that person won’t want to “fix” it and is happy as it is. And by commenting, you are putting yourself in the category of people who “care about looks” and therefore would be also judged by your looks. People tend to date people with similar values and that run in the same social circles.

So take it as you want. But if for you looks > personality, chances are that people that think that personality > looks discard you. And then you should focus on your own looks because that is the category you have put yourself in. The other way around, if you value personality over looks, then you should start offering opportunities to people who don’t have perfect bodies.

As for things you can’t change, there are plenty of things we can’t change. It is a matter of time to get old, get wrinkles and not look as we did when we have 20 something. And people tend to gain weight too because work and life don’t let you that much time to go to the gym. And some people don’t want to diet all the time. It is a valid choice. My advice is to choose people who would like or at least won’t mind those things that you can’t change.

And it is quite rational of women to not want to date people who value them just for how they look. After all, that would mean that the relationship is “dated” and only would last as long as they remain young.

So ask yourself what do you value more and act accordingly. That includes prioritizing.
