The waist-to-hip (WTH) ratio is a common measure of fat distribution. Your WTH ratio can help you track your weight loss progress, while also serving as a warning about your estimated health risk for problems related to being overweight, such as diabetes, stroke and heart disease.
Use a measuring tape to measure your waist (at the smallest circumference of your natural waist, usually just above the belly button) and the circumference of your hips (at the widest part of your buttocks). To determine your ratio, simply divide your waist measurement by your hip measurement. Compare your result to the appropriate chart below, which is different for males and females.
