When you're actually proud of, or at least don't care about some aspect of your physical appearance, you don't go out of your way to hide it, even if it doesn't conform to mainstream beauty standards. For example I have a fivehead (or tenhead maybe) but it doesn't bother me, in fact I think it makes me look intelligent, so I wear swept-back hairstyles even though people have actually said to me "maybe you should get a fringe".  Yet these fatties who loooove their flab so much always try to fatfish. Sure, they might post those creepy "body positive" shots with all their flab hanging out (which I personally consider to be exactly the same as pro-ana body shots, mentally ill), but when they need to look 'their best' they always try to fatfish - on online dating sites, in their avatars, in any shot that they put their identity to - they are always showing themselves looking their slimmest possible. If they really didn't care about that double chin they would display that it their avatars.
