Brief Summary:
Hypothalamic obesity (HO) is an obesity secondary to an alteration of the functioning of the hypothalamus, the central organ of energy homeostasis. The causes of OH are related to an hypothalamic lesion (eg craniopharyngioma) or to genetic diseases (ex: Prader-Willi syndrome). OH, which accounts for about 5 to 10% of obesity, is a complex handicap characterized by severe obesity associated with eating disorders, cognitive and behavioral disorders and sometimes a visual deficit, with a major impact on quality of life, morbidity and mortality. There is currently no specific treatment of HO. Management is essentially behavioral, based on daily support of eating behavior and physical activities (PA). OH is characterized by an intense and almost permanent hunger felt, a satiety disorder and an obsessive interest in food. The food education of the entourage is essential, the advise concern the control of the access to food and the setting up of a precise food frame on the quantities, with low energetic density, and schedules. OH is characterized by obesity with lean mass deficit. PA must therefore be regular, adapted to the disability and personalized to take into account cognitive deficits and behavioral disorders. Although the supervision of meals and daily PA is now recognized as fundamental in the care of these patients (National Program of Diagnosis and Care established by the French "Haute Autorité de Santé"), few studies have evaluated the effectiveness of programs with personalized support on global health. The investigators hypothesize that a personalized 4-month individual home-based counseling program on dietary counseling and PA can be effective to modify behaviors such as diet and PAs with an impact on changing weight and quality of life. The 16-week program includes a dietetic component (initial assessment with dietary care plan followed by a 30-minute telephone interview every month with dietician) and a PA component (two 1-hour individualized sessions, performed at home and supervised by a PA educator). Before and after the program, the investigators will evaluate habitual PA with an accelerometer, feeding behavior, physical functioning, weight change, body composition, quality of life and will constitute a biobank of serums, adipose tissues and stools. If the effectiveness of this program is demonstrated this will help to find ways to sustain this support by the institutions, to train professionals in the complex accompaniment of these patients. Finally this program set up as part of a rare disease can show the benefits in other populations of more common pathology (common severe obesity, intellectual disability, behavioral disorders).

Primary Outcome Measures :
  1. Compare the activity count (counts/mn) and pattern of activity (sedentarity time, light, moderate in %) measured objectively by an accelerometer before and after a 16-week program including a dietetic component and a PA component. Support over 4 months. [ Time Frame: month 4 ]
    PA volume indicator (taking into account the duration and intensity of the APs used) expressed in counts per minute, measured for 1 week objectively by an accelerometer (Actigraph GT3X®).advice and food intake control and a program of adapted physical activities at home in individual support.

Secondary Outcome Measures :
  1. Measurement of weight in kg before and after the 4 months program [ Time Frame: month 4 ]
    In day hospital before and 4 months after supervised program (weight measured during the evaluations) and monthly measurement at home of the patient during 4 months (reported by the patient and his entourage and recorded by the dietician during the monthly telephone interview).

  2. Evolution of the parameters evaluating the feeding behavior [ Time Frame: month 4 ]
    Score of Dyckens questionnaire ( 3 subscores behavior, drive and severity) before and after the 4 months program

  3. Evolution the physical function before and after the 4 months program [ Time Frame: month 4 ]
    A 6-min walk test distance (meters)

  4. Evolution of body composition (fat mass in kg and % evaluated by DEXA) [ Time Frame: month 4 ]
    lean mass and fat mass in kg and in% (DEXA)

  5. Evolution of the quality of life [ Time Frame: month 4 ]
    self-questionnaire of the patient (SF12)
