This is equiavalent for a man to attract women if he has no money and no potential.
Simply put, it can't be done. There will be men who will pick you up, but much fewer.
So the best thing to do, is to simply look better. You can become physically healthy by exercising and wear a bit of make-up. This solution is much easier than trying to find sane, healthy men who is attracted to fat, ugly women.
