"Funnily Ancel Keys never wanted BMI to be used as a measurement of obesity with his
original paper explicitly warning against the use of the body mass index for individual classifications. Keys knew that a nice simple number like the BMI couldn’t take into account differentials like gender, age, muscle mass, bone density etc. Keys was simple trying to find a means of conducting large scale health studies as accurately as possible."
Almost all of us have encountered the body mass index (‘BMI’) metric at some point in our lives. This measurement has become increasingly common as a health indicator, and as we’re increasingly warned about the obesity epidemic sweeping parts of the world, it’s nearly impossible to ignore the...
