Tracking your fitness progress is a pretty straightforward business if you record the weights you lift or take advantage of specially designed watches or apps. But the type of data you can get isn’t quite as good at showing how healthy you are. Visceral fat, the type that is around your organs, for example, isn’t easily detected, and cholesterol can be high regardless of how often you exercise.
In fact, tracking all the significant stats that indicate how healthy you are can be quite a job if you are meticulous about it, so it shouldn’t come as a surprise that a one-size-fits-all formula has gained widespread traction. That everything-to-everyone set of numbers is the Body Mass Index (BMI), and it has been used for all sorts: from informing government policies, to academic research and insurance qualifying standards. It’s also been around as a height-and-weight-based mathematical formula since Adolphe Quetelet created it in 1832, but it has a long and growing list of critics.
“It was basically developed by a Belgian statistician who was just interested in variation in bodies,” says Jeff Hunger, assistant professor of psychology at the University of Miami. “He wasn’t interested in health or wellbeing at all. “It wasn’t until the 1970s when physiologist and health researcher Ancel Keys took hold of this formula and thought that it could tell us something about health. In the past 40 years, research has shown that it can’t.”
QUICK AND CHEAP
Hunger co-authored a study led by the University of California, Los Angeles (UCLA) three years ago, which revealed some significant flaws in BMI when it was published in the International Journal of Obesity.
