Abstract Weight restoration is crucial for successful treatment of anorexia nervosa (AN). Without it, patients may face serious or even fatal complications of severe starvation. Renutrition should take into account clinical characteristics unique to these patients, such as gastroparesis and fear of gaining body weight. The efficacy of tube feeding and home-tube feeding (Home-TF) has been suggested in AN and proven in bulimia nervosa (BN). TF and home-TF allow a better body weight gain (mainly fat-free mass) in AN patients and a strong decrease in the frequency and the intensity of binge-eating/purging episodes at relatively short-term (1year) in BN patients. In AN, home-TF does not increase anxiety, depression, or worsen the eating behavior. In BN patients, home-TF decreases anxiety and depressive state and improves the quality of life. The goal of home-TF is not to cure the patients, but only to avoid serious malnutrition and its complications and to insure a better investment of the patients for their psychotherapy. Home-TF must be associated with psychotherapy, namely cognitive behavioural therapy and family therapy in adolescents. If the fear of gaining body weight is too high, the risk of failure of home-TF, because of poor compliance, is increasing. In any case, the aims and the goals of home-TF should be extensively explained.
