FAQ

BMI calculator FAQs

These cover the main questions people have before they use BMI as part of a broader training or fat-loss plan.

What is BMI used for?

BMI is a screening tool that compares weight to height. Healthcare providers use it to help classify weight type and to flag when a fuller health conversation may be useful.

Is BMI the same as body fat percentage?

No. BMI does not separate fat mass from muscle mass. It is one quick estimate, not a direct measure of body composition.

When is BMI less useful?

It is less useful for athletes, bodybuilders, children, teenagers, people who are pregnant, many adults over 65, and people with significant muscle loss from medical conditions.
