BMI (Body Mass Index)

"My sibling is a full-time professional athlete, works out every single day of the year including Christmas, is built like a brick wall, and is... literally 1 pound overweight. Studies have shown that if anything, BMI underestimates how fat people are. A good number of people who are in a healthy BMI"

"In fact, the low end of overweight (25-27 BMI) is actually a healthier range in terms of longevity compared to the low end of normal (18.5-20 BMI) or the slightly underweight range (17 BMI-18.5 BMI). Just a PSA for the 18 BMI chainsmoking alcoholics who take pride in having a low BMI."
