Body Mass Index

What is Body Mass Index (BMI)?

BMI (body mass index, BMI), which expresses the ratio weight/height2 (in kg/m2), has a good correlation with the percentage of body fat. In 1998, the U.S. National Institute of Diabetes and Digestive Diseases and Kidney and other National Institutes of Health issued the first guidelines on the identification, evaluation and treatment of overweight obesity. Usually the same normal range is used for men and women and adults of different ages after it was found that correlations BMI and mortality - morbidity are similar.

The Body Mass Index (BMI) (or BMI - Body Mass Index) is calculated as follows:


Weight Height 


Classification of obesity based on BMI


Morbidity Risk

<18,5 (Underweight)

Low (increased risk of other clinical conditions) // Make sure you eat a healthy and balanced diet!

18,5-24,9 (Normal weight)

Medium // Make sure you eat healthy and balanced diet!

25,0-29,9 (Overweight)

Increased // Consult doctor / dietitian!


30,0- 34,9 (1st degree)

Very increased // consult your doctor / dietitian!

35,0- 39,9 (2nd degree)

Seriously increased // consult your doctor / dietitian!

>/ 40 (3rd degree)
