What is Body Mass Index or BMI?

Body Mass Index is a simple, reliable index used as an indicator of underweight, normal weight, overweight and obesity.

It is calculated by dividing weight by the square of height. It is mainly used to separate weight categories that may lead to health problems.

Often BMI is used to measure body fatness because it measures excess weight. Simply it is the adjusted weight for a particular height. Because of its simplicity, anybody can measure their BMI using proper equipment with reasonable accuracy.

Formula for Calculating Body Mass Index

  1. Bodyweight in Kilogram and height in meter
  • BMI = Weight (kg) / Square of Height (m) 2
  • Unit of BMI: kg / m2
  1. Bodyweight in pounds and height in inch
  • BMI = (weight in pound/square of height in inch) x 703
  • Unit of BMI: lb/in2

Things to consider when using BMI

  • BMI can’t differentiate between fat, bone mass, and muscle mass.
  • It will not give any information about fat distribution.
  • Factors such as sex, age, muscle mass, and ethnicity can alter BMI

Note: BMI is inaccurate for athletes and bodybuilders. Since they have high muscle mass and bone density, BMI categorizes them as overweight.

So if you are an athlete or bodybuilder, don’t worry about your high BMI value.

History of Body Mass Index

BMI was developed by AdolpheQuetelet,  a Belgian mathematician, astronomer, and statistician. The name he gave to BMI was Social Physics. He also considered factors such as gender, age, etc. Actually, he was trying to find the statistics of a healthy man. The modern-day term Body Mass Index was first used in a paper published in the 1972 edition of Journal of Chronic Diseases by Ancel Keys.

Legislation of BMI

In Israel, France, Spain, and Italy, the use of fashion models having a BMI less than 18 is banned. This is implemented to prevent anorexia among models and others interested in fashion. 

BMI and Health Risks

High BMI values indicate a higher risk for certain diseases such as cardiovascular diseases, high blood pressure, type 2 diabetes, elevated insulin levels, breathing problems, gallstones, and certain cancers.
