To start, talk to your family doctor.

What is my BMI?

You can calculate your Body Mass Index (BMI) to assess your degree of obesity. To calculate your BMI, you need your height (in centimetres or feet) and weight (in kilograms or pounds).

This tool is not appropriate for you if you have an eating disorder, are pregnant, or are under 18 years of age.

If your BMI is over 25 kg/m2 and your waist circumference is higher than your recommended value, you are at a greater risk of developing obesity-related diseases.

Calculate your BMI

You can use several tools to calculate your BMI.

*These values are independent of age and sex and represent the same level of fat tissue for any population.

*It is important to measure BMI and body fat distribution (waist circumference or waist-to-hip ratio, etc.) to assess the risks of obesity-related health problems.

Waist circumference

Waist measurement

In addition to posing a risk for the conditions mentioned above, abdominal fat is a major risk factor for non-alcoholic fatty liver disease (also known as “NASH”) and other metabolic diseases.

To calculate your waist circumference, /typo3conf/l10n/fr/rtehtmlarea/Resources/Private/Language/fr.locallang_accessibilityicons.xlf:external_link_new_window_altText watch this video from the Heart & Stroke Foundation.

Perform the following steps:

  1. While standing in front of a mirror with your feet shoulder-width apart, run a tape measure around your waist (do not measure over your clothing).
  2. The tape should be at your belly button or just above your hipbones. It should be horizontal and not twisted anywhere. Breathe normally.
  3. Find the number opposite the edge of the tape.
  4. Compare this number with what is shown below. If your waist circumference is higher than what is indicated, you have a risk of associated diseases.

Men: More than 94 cm (37 inches)

Women: More than 80 cm (31.5 inches) 

Does your BMI and/or your waist circumference indicate that you have a weight problem? Don’t panic: we can help!
