Another way to determine if your weight is placing your health at risk is to measure your waist. Waist measurement does not determine if you are overweight, but it does indicate if you have excess fat in your abdomen. This is important because extra fat around your waist may increase health risks even more than fat elsewhere on your body.
Women with a waist measurement of more than 35 inches and men with a waist measurement of more than 40 inches may have an increased risk for obesity-related diseases.
