Given that I like very slender women, it's bad.
The fact that there are fewer slender women, is not equalized by men gaining weight causing less competition. The reason is that women don't put the same amount of importance on body that men do. Don't get me wrong, women aren't generally into overweigh guys, but women do have a fairly broad range of what they find acceptable in a male body, and having a few extra pounds on a guy just isn't seen as a bad thing by the majority of women. Men tend to carry their weight better than women as well, and have an easier time managing their weight than women (due to hormones).
But now that fat is ok, and now that "thic" has been fetishized by pop-culture groups, fewer women concern themselves with their weight and they don't have to - they get plenty of attention from men while fat. The girls who are slender are now SO rare and SO sought after that they all think they are 10's and the competition is fierce. I don't blame the women for that though..... your SMV is judged by the opposite sex. If a slender woman with just an average face is being treated by men as a 10, then she is a 10. But it's not good for me since they are more rare, almost always taken, and the competition for the available ones is fierce.
