What does BMI mean?
BMI means Body Mass Index. It is a number that compares your weight to your height. In French, it is called IMC (Indice de masse corporelle).
The formula
BMI is calculated by dividing weight in kilograms by height in metres squared. For example, 70 kg at 1.75 m gives 70 divided by (1.75 times 1.75), which is 22.9.
The standard categories
| BMI | Category |
|---|---|
| Under 18.5 | Underweight |
| 18.5 to 24.9 | Normal weight |
| 25 to 29.9 | Overweight |
| 30 and above | Obesity |
The limits
BMI does not take muscle mass, age, fat distribution or other health factors into account. Two people with the same BMI can be very different. That is why BMI is a general guide, not a diagnosis, and does not replace medical advice.
How to use it
Use BMI as a starting point, not as a conclusion. If you have a question about your health, talk to a health professional.
