The Verdict Is In: The BMI is a Poor Predictor of Health

  1. I agree that the BMI is a poor predictor, but it is usually used along side other measurements, such as waist circumference, so I think that makes it more accurate. I think personal judgement is also a good way to think of it, I mean if someone is an athlete with really high muscle mass, their BMI might be through the roof but if we use judgement, it is obvious they are healthy!

      Believe it or not, I have worked in health care for the last two and a half years and I have yet to come across any doctor or dietitian who has a measuring tape or who takes waist circumference at patient appointments. More often than not, BMI is THE diagnostic go-to at appointments. This has even been my personal experience with doctors – they are not using waste circumference at all (never mind that I have my own issues around that tool as well, but at least there is more evidence for it).
