It would be interesting to see a chart normalized to Americans vs. Others with similar BMI ranges. For example, Americans with 18-25 BMI (I know you're out there!) vs. French with the same.

By taking out those with a very general correlation for 'does not take care of their own health', we'd get a truer measure of the relative effectiveness of the respective health care systems.

"Taking care of your health" is in significant part an outcome of your health care system.

BMI is a poor indicator of health and and even poorer indicator of whether one takes care of themselves. In the US, unhealthy food is abundant and strongly advertised. Much of the country is sprawl where the only way to really get around is by car. People are more stressed and work longer hours & don't have the time to cook for themselves or exercise. The US lacks universal healthcare, some people live in food deserts where healthy food is not accessible, etc. The United States has such terrible infrastructure and social programs that it's unfair to pin people's poor health entirely on their own decisions

> BMI is a poor indicator of health

But it's an available statistic.

If we had doctors report on body fat % (even done with shotty capacitance) or hip/waist ratio we'd be better off.
