What I'm trying to figure out is how every individual state can be below the US average. I didn't think that was how averages worked or am I missing something? Are there different definitions of obesity?
If you're talking about that graph, it's the percent obese, not the percentile rank.

Exactly. So the US average is about 40% in adults and no state on that graph is much higher than around 36%. Which wouldn't make sense. I think the clue is a line in Wikipedia -
"Care should be taken in interpreting these numbers, because they are based on self-report surveys which asked individuals (or, in case of children and adolescents, their parents) to report their height and weight. Height is commonly overreported and weight underreported, sometimes resulting in significantly lower estimates. One study estimated the difference between actual and self-reported obesity as 7% among males and 13% among females as of 2002, with the tendency to increase"
Bump all those states up by that estimate and you could see where the 40% comes from. So presumably the national figure is derived some other way than self reporting and avoids that error. Which is why it's higher. No biggie just seemed odd.
