What is BMI?
Body Mass Index (BMI) is a simple ratio of weight to height that is commonly used as a general screening measure.
Why context matters
BMI does not directly measure body fat or distinguish muscle from fat. Athletes and people with different body compositions can therefore have BMI values that do not fully describe their health.
Use BMI as one data point
For a broader picture, consider other factors such as waist measurements, activity, nutrition and guidance from a qualified health professional.
