Does being a morning person increases one's chances of developing an eating disorder? Researchers have found a bidirectional association between anorexia nervosa and morning chronotype - the natural inclination of the body to wake up and sleep early.
Anorexia nervosa is an eating disorder that causes an intense fear of gaining weight. People with the condition have a distorted body image that makes them severely restrict the amount of food they eat. To prevent weight gain, they may resort to vomiting after eating, exercise excessively, or misuse laxatives, diet aids, diuretics, or enemas.
