What hath globalization wrought? This article talks about the cultural transformation happening Nigeria with the success of a thin Miss World. An excerpt:

Among the Calabari people in southeastern Nigeria, fat has traditionally held a cherished place. Before their weddings, brides are sent to fattening farms, where their caretakers feed them huge amounts of food and massage them into rounder shapes. After weeks inside the fattening farms, the big brides are finally let out and paraded in the village square.

This kind of sounds hilarious. I wonder how popular buffet chains would be in Nigeria if it ever became prosperous enough to sprout a consumer culture. On an aside, many extremely thin women aren't particularly attractive to heterosexual men. It happens to be that women and gay men tend to care more about fashion and pageants than straight men and so the women that are successful in these fields don't necessarily reflect the preferences of straight men. Take a look at the women in the SI Swimsuit issue and take a look at some tape of the runway, and you'll see that the former are a subset of the latter. The more cadaverous of the runway models would only be the fantasies of deviant males.
