More burger variety = less obesity. This is a very counterintuitive result.<p>I would like to see two other breakouts:<p>1) Quantity of Burgers ordered (as opposed to Burger options) versus obesity.<p>2) Fast Food Options versus Obesity.<p>My guess is that populations that eat at McDonalds and Burger King tend to be more obese, no matter how many options they have. I would enjoy seeing data on this.<p>Econometrics can be very interesting.
I suspect that "burger diversity" is just a proxy for wealth. The wealthier a county is, the greater the availability of healthy food. Plus you can probably afford a gym membership and/or can walk/jog/bike outside without worrying about being mugged.
