Frequently asked questions
What BMI ranges does Canada use?
Health Canada and the Public Health Agency of Canada use the standard WHO categories: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese.
Is BMI an accurate measure of health?
BMI is a simple screening tool based only on height and weight. It does not distinguish muscle from fat and may misclassify athletes or older adults. A healthcare professional uses additional measures for a full assessment.
