The number on the scale may not be the best indicator of your health and risk for disease. Even people in the normal-weight range are at increased risk of diseases like heart disease and cancer if they carry fat around their middle. A better indicator is your waist-to-hip ratio (WHR). It is found by measuring the smallest part of your waist and dividing that by the measure of the widest part of your hips (buttocks). The ideal WHR is <.85 for women and <.9 for men.
