BMI (Body Mass Index)

Definition

A ratio of weight to height that health professionals use to categorize populations while admitting it's not great for individuals (looking at you, muscular athletes).

Example Usage

Her BMI is 23, which falls in the 'normal' range despite her athletic build.

Fun Fact

BMI completely ignores muscle mass, which is why jacked athletes can have 'overweight' BMIs.
