Analysis of the Glycemic Profile of People Suffering From Compulsive Eating Disorders Aiming to Offer an Innovative Nutritional Approach (GLUCOPULSE)

Study Overview
=================
Brief Summary
-----------------
Eating Disorders (ED) are a major public health problem. Current care remains only partially effective and the pathophysiology of the disorders remains to be deepened. With regard to compulsive ED (bulimia and binge eating disorder), our clinical experience suggests that one of the major triggers for crisis may be related to glycemia. In fact, bulimia could be considered as a vicious circle where the binge eating disorder is going to be followed by a food restriction in order to control weight , putting the subject in a situation of energy deficiency which will favor the emergence of new crises . Technological advances have resulted in the emergence of new measuring devices, such as tracking, which records continuous glycemia, which would allow us to explore these clinical hypotheses.

Detailed Description
-----------------
This is an open-label, exploratory, proof-of-concept study. 20 patients will be recruited from the day hospital of the Endocrinology and Nutrition Department of the University Hospital of Montpellier, Lapeyronie and from Emergencies and Post-psychiatric Emergencies Department. During the inclusion visit, the dietician will explain to the patient the use of the dietary book and the glycemic sensor which will be allocated to it. The patient will also answer to self-questionnaires about his eating behavior. No nutritional approach will be addressed so as not to alter the patient's eating behavior and not to influence the results. They will be followed-up during 14 days.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frequency of episodes of bulimia (measured from the dietary book) according to the interstitial glucose levels | Each information entered on the dietary book will be positioned on a chronological axis allowing to identify precisely when the eating disorder occurred | At the return of the dietary book (14 days after enrollment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Levels of impulse to make a crisis and food obsession and hunger depending on interstitial glucose levels | Each information entered on the dietary book will be positioned on a chronological axis allowing to identify precisely when the eating disorder occurred | At the return of the dietary book (14 days after enrollment) | 
| Dietary patterns | Measured by the Emotional Appetite Questionnaire (EMAQ), 1 represent a food intake much smaller than usual ; 9 represent a food intake more significant than usual ; 5 represent a food intake as usual | At enrollment |
