One of my pet peeves is the idea that BMI provides an accurate indication of individual health. It doesn’t. It’s useful across populations (and may be useful to individuals to monitor progress), but when it comes to indicating which individuals are “healthier”, BMI fails miserably – and our new Sciblings at Obesity Panacea do a great job of explaining why.
If, as a policy matter, we want to differentiate between the healthy and unhealthy – which is a big if, depending on how libertarian you are – let’s make such assessments meaningfully, using a workout that proves general endurance and cardiovascular health. BMI is far too influenced by genetics/body type. I look forward to more solid posts like this from Obesity Panacea to counter popular misconceptions about weight and health.
