What does this mean for you?
Healthy:
A Waist-to-Height Ratio (WHtR) of 0.4 - 0.49 is considered to be within the healthy range. Maintaining your WHtR around this range and a healthy BMI score is likely to reduce the risk of obesity-related health issues. A good tip to remember is to aim to keep your waist circumference to less than half your height.
