Why do I like fatties so much? Is it hormonal?
No no no. With respect, I think you may be looking at this slightly wrong... *ahem*
...although these women are indeed heavy, they are not gross like those pigs we all see with their big fat aprons of flesh hanging down. And titonas are a must - flat chests on a fat girl don't count here...
And you (we both

) are still feeling our 'hunter-gatherer' genetic calling - by sight, we are judging these girls to be drought and famine resistant, and therefore capable of keeping our families alive while we are out hunting on the Savannah for weeks at a time! Hahaha!
It's in your bones, man...
