There's an interesting discussion going on over at Diet-Blog about the The BMI Project. Started by a blogger who discusses fat acceptance issues, the BMI Project is a set of personal photos that include height, weight, and BMI.

BMI is often criticized as being a flawed tool when it comes to measuring cardiovascular risk or even physical fitness. Because BMI doesn't take into account body composition, it's especially inaccurate for those who are highly muscular (athletes, body builders) or those who are especially thin, but have low muscle tone. Experts are beginning to believe that a waist-to-hip ratio or simply a measurement of the waist circumference may be a better way to assess cardiovascular risk.

The debate at Diet-Blog stems from whether The BMI Project exposes BMI as a flawed measurement, or whether it appears to be generally accurate. It's a spirited discussion, and I'm curious to see what you think. To understand better why BMI is not very accurate for athletes, check out this photo of an accomplished triathlete, whose BMI qualifies her as overweight.
