Obese by what metric? The back-and-forth of this discussion about BMI is entirely predictable, but doesn't it sort of miss the point? Isn't it possible -- and I mean this sincerely, even though it's wildly simplistic -- to just look at a human and determine if they're carrying around excess fat? A lot of times when I hear people saying that BMI doesn't account for how much they exercise, I'm looking at the person saying it and they appear unfit. On the other hand, do we need BMI to tell us that a fit person is fit? What am I missing here?
