Did some one screw up the data? Or is the BMI equation that screwed up? Or have health-nazi-bureaucrats been playing games with the definitions of "normal"? Or both?
The BMI equation will label many very fit athletes as "over-weight". And people into weight-lifting and body-building are off-the-BMI-charts! The bottom line, IMO, is that people vary too much for there to be a one-size-fits-all equation to define "fit" or "normal".
FWIW, I've been over-weight or obese almost my entire life, and would love to lose 30-50 lbs. (having already lost 90 or so the past 3 years). I've also walked/run several half marathons recently (which typically have 3.5-4 hour time limits for completion). So what does "fit" mean?
