Treatment of the Metabolic Syndrome in an Interdisciplinary Obesity Clinic: a Randomized Controlled Study

This study is a randomized, controlled and opened trial designed to compare the effects of an interdisciplinary moderate-intensity lifestyle modification program vs. conventional treatment by primary care physicians. We want to show the benefits of coherent interdisciplinary care in the obesity clinic of CHUS (Centre Hospitalier Universitaire de Sherbrooke) in comparison to the conventional treatment in order to: * Improve subjects\' characteristic features of metabolic syndrome: weight, waist circumference, fatty mass, plasma lipid profile, blood pressure, fasting glycaemia, and HbA1c; * Improve our patients\' nutritive practices; * Decrease our patients\' sedentary lifestyle; * Improve our patients\' motivation to lose weight, and to improve their quality of life; We also wish to define predictors of answer in order to better select the patients if necessary, and evaluate the costs incurred by the health system.
