And yet the bogus Body Mass Index insists that men and women should be of identical ideal body weight to height regardless of the composition of that "weight".
What? I'm not sure of what you are saying.
NO BMI requires any kind of sameness with gender or age.
Men and women the same weight if they are the same height? NEVER, in any context. Men are ALWAYS heavier. Their muscles are thicker. Bones are bigger.
From the Internet: http://en.wikipedia.org/wiki/Body_mass_index
'BMI' provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss overweight and underweight problems more objectively with their patients.
However, BMI has become controversial because many people, including physicians, have come to rely on its apparent numerical authority for medical diagnosis, but that was never the BMI's purpose; it is meant to be used as a simple means of classifying sedentary (physically inactive) individuals, or rather, populations, with an average body composition.
Move more; eat less. It is that simple for most people. The BMI was in vogue YEARS and YEARS ago but now it's just a simple tool that SOME doctors still use.
