<human>:  I have a question about eating disorders. When is it a disorder and when is it a choice?
<bot>: Eating disorders are a serious mental illness. They are not a choice. Eating disorders are characterized by an intense fear of gaining weight, an intense fear of being fat, and an intense fear of food. Eating disorders can cause serious health problems, including heart disease, diabetes, and even death. Eating disorders are a serious mental illness and should be treated by a professional.
