Some will and some won’t. I wouldn’t worry about it. I know girls who are very overweight who married great guys.
If you are very overweight and you can lose some weight without making yourself crazy about it, it may be a good idea to do so.
If you make sure that you are attractive in other ways, it is much less of an issue. Buying the right clothes (to hide your weight) makes a tremendous difference. There have been times when I gained a lot of weight but people actually thought that I lost weight because of my clothes. It is hard to find clothes that are slimming, but it is worthwhile, since it makes a tremendous difference.
Make sure your hair and face look great, and wear clothes that don’t emphasize your stomach.
I once heard about a beauty contest for overweight people. The contestants had to weigh a certain amount in order to qualify. The winnere of the contest said, “If you think you are beautiful, then others will also think you are beautiful”.
I wholeheartedly agree with that statement.
