Evaluation of the Impact of Physical Reconditioning Associated With Specific Nutritional Supplementation in Obese Patients Suffering From Metabolic Syndrome (OBEFITT)

Evaluation of the Impact of Physical Reconditioning Associated With Specific Nutritional Supplementation in Obese Patients Suffering From Metabolic Syndrome. OBEFITT Study.

Android obesity contributes, via insulin resistance and endothelial dysfunction, to the development of cardiovascular atherosclerosis. It leads to poor quality of life. It is often associated with metabolic syndrome which includes, whatever the definitions used (National Education Cholesterol Program, NECP / Adult Treatment Panel III, ATP III or International Diabetes Federation, IDF), an increased waist measurement, an arterial high blood pressure and disorders of the glucide and lipid metabolism. The treatment of the current "epidemic" of obesity and metabolic syndrome in France (12.4 % of obese and 14 % of subjects with metabolic syndrome) thus requires new therapeutic approaches.

A well-balanced diet and a daily physical activity are the indispensable requirements for the treatment of obesity and metabolic syndrome. It is possible to associate it to pharmacological agents, but the results are often partial and transient. Preliminary data suggest that leucine or arginine supplementation could facilitate the loss of fat mass. Moreover, the physical exercise has also demonstrated benefits.

Sessions of physical reconditioning (aerobic work + muscular intensification) associated with a program of specific nutritional supplementation by a mixture of Leucine and Arginine (in the daytime) could improve the treatment of obese subjects affected by metabolic syndrome.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: S: Nutritional Supplementation alone; Specific nutritional supplementation for six months by 30g per day of a mixture of amino acids (21 g of L-Leucine and 9 g of L-arginine), to distribute during each of the 3 main meals.	Dietary supplement: L-Leucine and L-arginine; Specific nutritional supplementation for six months by 30g per day of a mixture of amino acids (21 g L-Leucine and 9 g of L-arginine), to be distributed during each of the 3 main meals.
Active Comparator: A: Physical Reconditioning alone; Physical reconditioning sessions led by a trainer three times a week for 6 months.	Other: Physical Reconditioning by a trainer; Physical reconditioning sessions begin with a warm-up for five minutes for the type of effort made, and then correspond to a sporting course composed of elements of strength training and / or aerobic exercises and will be completed by a return to simple stretching and general advice on managing their physical life. The duration of each session will be 45 minutes at the beginning of the protocol and then gradually increased over time to achieve 1:30 of total physical activity at the end of protocol.
Active Comparator: AS: Physical Reconditioning + Nutritional Supplementation; Association for six months of a specific nutritional supplementation by 21 g of L-Leucine and 9 g of L-arginine per day (to distribute during each of the 3 main meals) and of physical reconditioning sessions three times a week.
No Intervention: C: Lifestyle counseling; Usual advice given in consultation on the need for a balanced diet and regular physical activity
