I am in upstate New York, specifically the Capital Region. I think here is a pretty accurate cross-section of America - it seems of the people I see, a little under a third are obese, most are somewhat overweight but not by too much, and with people my age, fewer are overweight but still many are.
I've never gotten the "oh god eat more" talk from anyone my age - it is becoming fashionable and mainstream to care about nutrition and eat fresh/local/whole food. Still, most people in the region aren't too concerned and the most successful businesses here are chain restaurants and BBQ joints.
Talking to friends in other areas of the country/other countries, I hear a lot about how EVERYONE in the Midwest is very overweight, and how in LA it's fashionable to be waifish vs. slim but solid. What's your take on your area and what have you noticed on your travels? The only time I've left the Northeast US in the past 5 years was when I visited relatives in a very affluent part of Michigan, where I noticed very few people were heavy.
