Just so you know, I'm not gonna say looks doesn't matter

but it doesn't matter if you lose all that fat, get a hair cut, some new clothes, etc look good and you could still be single.

Changing appearence is one thing which is easier, you also have to change your lifestyle which is easier said than done.
I don't want to be rude but I think its a bit shallow to be well fat like youself and still look down on other fat people like that,

If you can't change yourself don't expect some hot chick with just start going after you Unless you have an insane personality.
