Frequently asked questions
- What is a healthy waist-to-height ratio?
- A WHtR below 0.5 is generally considered healthy for both men and women. Research shows WHtR is a better predictor of heart disease risk than BMI alone.
- How does WHtR compare to BMI?
- WHtR captures abdominal fat distribution, which BMI ignores. A person can have a normal BMI but still carry excess belly fat — WHtR catches this.
