 The body mass index (BMI) [1] or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as

the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height
in metres. The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person
as underweight, normal weight, overweight, or obese based on that value. [2]
