Calculate your Body Mass Index (BMI)

April 2017

Body Mass Index (BMI), is a guide used by healthcare professionals to determine if a person is overweight and might be statistically exposed to medical complications. It uses your height and weight to calculate your BMI.

The BMI is a guide to what weight is most appropriate and healthy for a person.
People from 20 to 65 years old can use the BMI.

Breastfeeding or expectant mothers, sick people and major sportsmen must not refer to this measure.

The BMI is calculated by dividing a person's weight in kilograms by their squared of your height in meters: BMI = weight (kg)/size (m2).
  • <A normal BMI is between 18,5 and 24,9
  • A score of 25 to 29,9 suggested being overweight. Take care, avoid over eating, snacking in between meals. Eat a well balanced diet low in fat and sugar and exercise regularly.
  • Obesity is considered when the score is above 30. In this case, there are considerable risks to your health and seeing your GP is recommended for further advice.


Always week advice before restricting the food you eat and get sensible advice from appropriate healthcare professionals.

A worldwide study of 170.000 people in general practice on 18 to 80 year olds, confirms that being overweight is a major health problem in many countries.

Between 50% and 66% of the world population is overweight or obese.

Diabetes and cardiovascular diseases are the most common complications which is parallel to an increase in BMI and waist measurement.

A 14% increase in waist measurement increases the risk of heart disease from 35% to 40%

More than 60% of men and more than 50% of women have a BMI greater than 25.

Physical activity and a well-balanced diet remain the most important factors in the prevention of obesity.
