It's no secret that fat guys prefer skinny chicks and are repulsed by fat chicks. Most men find fat chicks repulsive. I am one of those men. It's not just their unsightly blubber that makes them so undesirable it's their behavior. Gluttons are fun but too many fat girl gluttons are a pain in the ass.
The other reason fat guys are into skinny chicks is purely pragmatic. It is either mechanically difficult or impossible for us fat guys to pork a fat girl even if we wanted to do so.

This is the next phase in political fat acceptance. The days of justifying our fatness by lying and saying we have a mysterious genetic or metabolic disorder are over. We now freely admit to and embrace what the fat haters would call gluttony. We fatlings are no longer apologists for our size nor our greedy gluttony. We are fat because we eat huge amounts of food and we like it. If you don't like it get used to it because fat people are now the overwhelming majority.
