"Sometimes a nutritionist is sought to provide a diet as an answer to the problems with bingeing. However, a diet is not the answer to an eating disorder. Many eating-disordered people are experts themselves on diets and food intake. They know what is healthy. They know the caloric intake of every morsel they put in their mouths. Some are professionals in the area of nutrition. This underscores that eating disturbances are not due to lack of information about a good diet, but have to do with psychological factors that keep people from putting this information to use. Often, a nutritionist and therapist work concurrently. The nutritionist sets the stage for healthy eating, and the therapist examines what gets in the way when someone can't keep to her food plan. The goal overall is that of allowing someone to eat when hungry, in moderation, and to understand what motivates problematic eating so that better choices can be made."
