Abdominal obesity and its metabolic consequences, particularly type 2 diabetes, require personalized nutritional monitoring. Today, it is not always possible to provide patients with appropriate care to both, the diet plan, physical activity, stress and sleep management. Emerging data have shown the effectiveness of remote support (e- coaching), in order to increase the level of physical activity and reducing calorie intake which causes weight loss similar to that obtained during a face to face consultation. Compared to a food survey conducted by a dietician, the dietary survey MXS computer software showed similar results on the collection of nutritional data. Furthermore, users preferred this method of remote collection compared to direct interview. The investigators recently developed a tool for e-coaching combining this computerized dietary survey and education and support modules on diet and physical activity (MXS- health program) for the patients. The aim of the investigators' study is to compare efficacy of this new software vs usual care.
