I live in Missouri. Response to fit people is highly variable, and seems to depend on the family. Some fat families here seem to see fit people with jealousy, not understanding how they stay so thin. Others just don't seem to care about their obesity and think of normal sized people as abnormal, like their sense of what is normal is completely shifted. Yet others are ashamed of their obesity, yet none of their attempts to change seem to work.

Mating behavior here seems to follow the norm. Fat people tend to date/marry fat people, and healthy people mostly stick with other healthy people.
