Your Waist-to-Height Ratio results:

Less than 0.4
Possibly underweight

What does this mean for you?

Take care:

Your Waist-to-Height Ratio (WHtR) result does not increase your risk of obesity-related risk factors.

A WtHR result of less than 0.4 may indicate that you are underweight. While you might not face the same health risks as people living with obesity, being underweight can still come with other health considerations. Consult your doctor for further support.

 < 0.4 Take care
 (possibly underweight)
 0.4 to 0.49 Okay
 0.5 to 0.59 Consider action
