Health professionals: Please, stop using BMI as a means of assessing the health of patients and clients. Everyone can look at a person and see if he or she is overweight, obese, morbidly obese, or underweight and in need of some muscle and fat on their bones. But when you apply arbitrary numbers into a formula, you’ve created an abstraction, and when you use it to assess whether a person is underweight, normal, overweight, or obese, you are guilty of reificiation (for those professionals who have never heard this word, please, it is a logical fallacy).

It is time to dispense with BMI. Stop using it because it makes you sound stupid, philosophically unsophisticated and intellectually lazy. Is that what you want?
