No argument there. My statement is that the definition of obesity has become so broad and wide that it no longer has the same meaning that it did a generation ago.
I see where you’re coming and yes there really are two definitions of obesity. There’s the common one which means people who are extremely fat, and there’s the technical definition that’s used by people who compile health statistics. The latter has started to pop up more and more as people have gotten fatter and the trend towards fatness has attracted more statistical analysis. The problem is that it’s based on a simple formula that tends to capture tall people and especially tall people who are muscular since it doesn’t distinguish between muscle mass and fat mass. That’s how you wind up with a football team whose players are technically obese but who are by no means obese according to the common meaning.
