Wonder if the obesity rates started to decline or is the definition of "obese" changed?

It did what you would expect any upward trend to do--flatten out and perhaps decline. Doesn't really require some magical solution--just math. Regression to the mean aided by more people aware of the problem and slapping those 64 ounce soft drinks out of their kids hands.

You are right to be suspicious though. The definition of overweight for kids is more variable than adults, for adults it's consistently BMI, while for kids there are height-weight and age-weight measures. The definition is consistent for the curve though. If the curve didn't flatten it would mean everyone is fat, and that doesn't happen.

It could just be that around 2000 there were no longer any people involved with the chart that could do the math to update it.

Actually I do remember reading about the BMI index, and how there was some debate at the outset about where the various categories (obese, etc.) should fall relative to a person's score.  Some people believed it was too strict--that it was suddenly classifying millions of "normal" people as overweight, overweight as "obese", etc. 

I doubt that's what's happening with the chart (that they'd change a definition in mid-stream) but the BMI is a dumb system, and treats tall and/or muscular people badly.  It's also ironic that while on the one hand society is working to reduce "body shaming", reduce people's (especially females') obsessions with diet and weight, etc. it's also doing things (using the BMI to tell tall people they're fat, sending "your child has a high BMI so is fat" notes home from school, etc.) directly the opposite.

I'd guess Michael Booth is a fatso based on his BMI, as are most professional athletes.

BMI is individually useless, but as a population measure, it's useful and relevant. Unless perhaps we're all becoming taller and more muscular.

On my long trip across the country in 2007 it was easy to see how fatness varies state to state. In Michigan, I'm a skinny guy.  And there's the Maui hotness measure that Chan told me about years ago--On Maui a male 10 is a 4 with a job.

Yeah, you may laugh, but I've talked to dozens or even hundreds of people with above-"normal" or increasing BMIs, and virtually every one of them will tell you it's because they've been increasing their height or percentage of muscle.

And they are all above average.

It's actually true in a Swedish study of such opinions, 93% of American drivers rate themselves as being above average. 69% of Swedish drivers do, which many Americans would interpret as meaning Americans are better drivers than the Swedes.

The bmi was actually a statistical concept created back in the late 1800's and was never interned to be applied as western civilisation has done. Blame your governments for that one.

It's functional as a measure of what a population is doing since it can be self-reported. All the more precise measures require either equipment people are unlikely to have access to or techniques that are too complex or error-prone.

"BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition"

http://www.medicalnewstoday.com/articles/265215.php

"Modern medicine tells us -> It's not the weight in kgs that you should be most worried about -> rather your fat percentage.  Because fat is the real problem.  The higher the BF% a person is the more at risk they are for health problems like heart disease - T2D - and high blood pressure."
