--like blood pressure, lung capacity, A1C, and so forth instead, as they are far better measures of total-body health, are far less likely to cause prejudicial physician interactions ("lose weight and see if that solves it"), and are better at detecting underlying causative health problems.
Maybe my favorite example of all this: Every single world-class powerlifter (and most strength-based athletes generally) are "obese" by traditional weight tracking measures, sometimes "morbidly" so. Which is *ludicrous*.
Yep, I mean that fact alone should be enough to remove body weight as a measure of health not only on an individual level, but even on populations. Everyone has a unique body composition!
Even when people wave that off as "you're not a professional athlete though", they usually shut up when I tell them that at my height and build (5'2, stocky), I would have to have *0% body fat* to have a "healthy" BMI
