In its 5 January 2013 issue the Economist
SIR - The body-mass index that you (and the National Health Service) count on to assess obesity is a bizarre measure. We live in a three-dimensional world, yet the BMI is defined as weight divided by height squared. It was invented in the 1840s, before calculators, when a formula had to be very simple to be usable. As a consequence of this ill-founded definition, millions of short people think they are thinner than they are, and millions of tall people think they are fatter.
So despite my highest-ever-fat content I'm not overweight anymore!
Mind you, if you trust professors from Oxford you deserve all you get
