I'm in Tennessee. I live in East Tenn now, but was born and raised for the most part in West Tenn...which is very rural and kind of backwoods. Imagine Andy Griffith.
MY opinion is that people in little Southern towns tend to be a little bit heavier than the norm. Women are thick and curvy...men are big and broad. And they also seem to be more accepting of different body types...I've never felt pressure to look a certain way or be a certain weight. It's got to have something to do with the cooking...food is such a big part of the traditional southern lifestyle...we really do celebrate with it, grieve with it, compete with it...everything. And it's all so GOOD. It's terribly rude to go to someone's house and refuse food around these parts.
This is a good and a bad thing. Good because the body image issues that I DO have are ones that I've created myself...I was not raised around supermodel thin people, I was encouraged to eat when I was hungry and to be proud of my curves. Bad because it's too easy to let myself slip when I've got people in my face telling me I'm already too thin and, don't I want another hunk of pot roast???
Just my opinion based on what I've experienced where I live. Good thread idea, I've wondered about this myself!
