The idea
Body mass index, or BMI, relates weight to height as weight in kilograms divided by height in meters squared.
In practice
Below eighteen point five is underweight; eighteen point five to twenty-four point nine is healthy; twenty-five to twenty-nine point nine is overweight; thirty or more is obesity.
Where people slip
BMI can mislead for athletes, people with swelling, and older adults who have lost muscle.
