•  Introduction to BMI

Based on height and weight, the BMI calculates a person's leanness or corpulence and attempts to quantify tissue mass. It is frequently used as a broad indicator of a person's body weight in relation to their height. According on the range the value falls within, a person is classified as being underweight, normal weight, overweight, or obese based on the value received from the BMI calculation. These BMI ranges are sometimes further subdivided into categories like severely underweight or very severely obese, depending on factors like geography and age. Even though BMI is a flawed indicator of healthy body weight, being overweight or underweight can have major negative health implications.

< 16	Severe Thinness
