# Waist-to-Hip Ratio May Offer Better Indicator of Obesity, Health Over BMI
Body Mass Index has long dominated how doctors assess whether someone carries excess weight. New research suggests waist-to-hip ratio offers a more accurate picture of health risk.
BMI calculates weight relative to height alone. It doesn't distinguish between muscle and fat, which matters because muscle weighs more than fat. Athletes often register as "overweight" despite being fit. Waist-to-hip ratio measures where fat sits on the body instead.
Where fat accumulates directly influences health outcomes. Fat stored around the midsection, called visceral fat, poses greater risks for heart disease, type 2 diabetes, and metabolic dysfunction than fat distributed elsewhere. Someone with a healthy BMI but excess belly fat still faces elevated health risks. Conversely, a person with a higher BMI but fat primarily on hips and thighs may experience fewer weight-related complications.
Calculating waist-to-hip ratio requires two measurements. Measure waist circumference at the narrowest point between ribs and hip bones. Measure hip circumference at the widest point around the buttocks. Divide waist by hip measurement. For women, a ratio under 0.85 is generally considered healthy. For men, under 0.90 is the target.
This metric resonates with parents tracking their children's health too. A child's BMI may suggest overweight status, yet waist-to-hip ratio reveals whether dangerous visceral fat is accumulating. This distinction helps doctors recommend appropriate interventions earlier.
Healthcare providers increasingly incorporate both measurements into assessments. BMI remains useful as a starting point, but waist-to-hip ratio provides context about actual health risk. Together, these tools paint a clearer picture than BMI alone.
