"Body Mass Index" is a rather bizarre thing:body.mass.in.kg / height.in.m^2I 
have never been able to find any biologicalor physical meaning for this.  Yet 
cliniciansare solemnly advised to measure the weight tothe nearest 0.1kg and 
the height to thenearest 0.1cm.How do you propose to determine the weight froma 
single image?  Even an R package cannot perform magic.On Mon, 1 Mar 2021 at

A quick search with the terms "BMI flawed" produces an enormous list of hits 
pointing out the problems with BMI as an index.  Here's one from a dozen or so 
years ago:

And a quote from that piece:

"The BMI was introduced in the early 19th century by a Belgian named Lambert 
Adolphe Jacques Quetelet. He was a mathematician, not a physician. He produced 
the formula to give a quick and easy way to measure the degree of obesity of 
the general population to assist the government in allocating resources. In 
other words, it is a 200-year-old hack."
As an index of obesity in individuals, BMI has some glaring flaws.
