The DSM-5 currently specifies two subypes of anorexia nervosa—the restricting type and the binge/purge type. Those who suffer from the restricting type of anorexia nervosa go to extreme lengths, such as over-exercise and starvation, in order to keep from gaining weight, whereas those suffering from the binge/purge type tend to overeat and then compensate through some method of purging. The distinction between the binge/purge type and bulimia nervosa is that those diagnosed with binge/purge type are below a healthy bodyweight, while those with bulimia nervosa are at least normal weight.
