End of the BMI? Hopefully so - What the Mayo Clinic is proposing:
Bottom Line: For as long as I can remember I've longed for the day when common sense prevailed and we'd put an end to the use of the BMI for anything deemed viable health info. Actually I remember the day pretty well. I was still in school during the peak of the sports playing days and had just completed a physical that determined that I had only about 5% body fat (I played football, baseball and ran track so I was a lean little guy). Anyway, shortly afterwards I received the results of my BMI reading. It stated that I was slightly over-weight because at just 5'6 my ideal weight was 136 and I weighed 145. I laughed. Unfortunately various medical authorities have perpetuated the BSI, my preferred acronym for the metric, on unsuspecting people for the past couple of decades. The good news is that common sense may be about to prevail.
The "BVI", or body, volume index - has been developed and is being pushed by the Mayo Clinic as a more credible number of weight/height information. The BVI considers what the inadequate BMI didn't - fat mass vs. lean mass. As any health 101 course should teach you - muscle weighs more than fat. So if you're in peak physical fitness the BMI frequently would suggest that you're at an unhealthy weight because it didn't know if you'd never attempted physical activity or you were an Olympic athlete. Lead on Mayo Clinic and may the BSI die a swift deserving death in the dust bin of history. Where it never should be found again.
