The formula for BMI is simply wrong. It's based on a square of the height. This would be great if we were two dimensional, but we're three dimensional. Tall people routinely have high BMIs and short people have low BMIs. I'm 6'5", and though I am at the 20th percentile of weight for people of my height, I have a BMI that indicates borderline obesity. And I'm skinny with about 12% bodyfat. It's just a weird measure. I'm not sure why anyone uses it.
