Body mass index or BMI is used to check a person’s total fat ratio to its weight. Its based on a statical approach to estimate a person’s fitness level. BMI never actually calculates the fat content in body but just guides men and women the level of fat they  may be reaching.

BMI is calculated as ratio of total mass of person in Kgs and square of height in meters.

mathrm{BMI} = frac{mbox{mass}  mbox{(kg)}}{left( mbox{height}(mathrm{m})right)^2}

if a person’s BMI is

  • less then 16 then he/she is considered Severely underweight.
  • 16-18.5 is considered underweight.
  • 18.5-25 is normal
  • 25-30 is overweight
  • over 30 is considered Obese.

bmi is used in many countries as a record set for patient suffering from eating disorders

BMI can be calculated easily and without any expensive equipment. However, BMI don’t take into account many factors such as body size and muscularity. The categories also fail to account for varying proportions of fat, bone, cartilage, water weight, and more.

Despite this, BMI categories are regularly considered as a good tool for measuring if a person is  “underweight”, “overweight” or “obese.
