[New questions and their solution in eating disorders]

Eating disorders represent a continuum in the pathological feeding behaviour with anorexia and severe malnutrition as one extreme and with psychogenic overeating and atypical forms of Eating disorders accompanied with obesity as the second extreme. World-wide epidemical spread of obesity and consequences of obesity frequently results in neglection of eating disorders problems and in apprehension of obesitologists that the Eating disorders prevention could challenge their efforts in the prevention of obesity. Because the scientific approach can enrich both fields, possibilities to improve cooperation between them in the fields of clinical and preventive care are studied. They are based on the recognition of common risk factors and in the more effective and aimed prevention and therapy. Some new discoveries in this field are discussed.
