Girls liking cute skinny guys really, really pisses off chuds. I can't tell you how many shlubby bearded gamer-bro types I've heard complaining about "girls like girlish boys not manly men like me nowadays, what the hell is going wrong with the world".
Your out of shape and unkempt appearance was never attractive gamers, there's not a horde of hot twinks out there stealing all the women you just don't care about your own appearance and stay inside all day. Have you tried going to mixed social events and being nice and funny? Have you taken some time working on your appearance to match your expectations? (If you want a woman who shaves and wears make-up, you better be bathing and styling your hair and getting nice clean outfits too)
