What does this mean for you?
Possibly underweight:
A Waist-to-Height Ratio (WHtR) of less than 0.4 is below the ‘healthy range’ and along with a low BMI score, 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 an evaluation and further support.
