Short History Of The Body Mass Index
It is interesting to note that, when BMI was created, it was not meant to be used on diagnosing individuals. It was meant to be used in comparing the boy fats of population, as a whole.
In other words, it is extremely useful as a shorthand way of comparing the relative body fat of American men versus men from Switzerland. However, it is an extremely poor and inappropriate tool when used to compare the body fat of Bob to Ted.
BMI has become so popular that even some physicians use it, without thinking, to diagnose weight disorders and prescribe corrective treatments.
BMI Measurements And Muscle Mass
If you happened to have a highly muscular build, your BMI measurements are more likely to misrepresent your actual level of fitness. This is because muscle weighs more than fat. And two people with the same weight can have dramatically different health outlooks depending on the percentage of Fat to Muscle in their body.
BMI Calculation Formula – How To Measure BMI
The non-metric formula for calculating BMI is as follows:
BMI = weight (lb) * 703 / (height in inches) x (height in inches)
