CDC has published it's latest obesity map for USA.

6 states exceeded 30% this year.

Colorado is still managing to stay below 20%.

If you look just at western states, in 1995, they were all light blue (10-14%). By 2005, they're all tan (20-24%). That's a 5-10% rise in just 10 years. That seems really fast. Draw a line through those two points, and we'll be 100% obese by as early as 2085 (except for Colorado).

Apparently the CDC study relies substantially on self-reported weight via telephone interviews. A research group at Harvard estimated how people (especially women) tend under report their weight in telephone interviews and wrote a paper examining obesity trends that took this information into account.

Bottom line, real obesity statistics are ~10% higher (~8% for men,~15% for women) than what you see in the maps. Since obese tend to lie about their weight more, this bias also suppresses the rate that obesity is increasing by about 10%. So we'll probably hit 100% obesity as early as 2070, but it will take us another 15 years before we admit it.

And that's when all the single chinese guys will invade the rest of the world.
