Quick Google suggests healthcare costs for obese people are <50% higher than non-obese and the US has 15-30% more obesity than these countries. So maybe 15% at most of the 100% higher cost per capita of healthcare is obesity related. The killer for me for that hypothesis is that within the set of countries with normal healthcare costs, there’s huge variation in obesity (10% in France to 30%in ireland) with limited variation in cost.
Maybe the life expectancy side does have more to do with obesity?
