 The Nonalcoholic fatty liver disease NAFLD is the most common form of liver diseases, affecting approximately 20-30 of the adult population and is more common in obese individuals 70-80. The main risk factors associated with the disease are the components of the Metabolic syndrome. To date, there is no specific pharmacological treatment for NAFLD and changes in lifestyle with weight reduction and exercise are always recommended. Few data exist on the impact of physical activity and optimal nutritional strategy for the treatment of NAFLD. Seen the need to elucidate the impact of physical activity and the search for an ideal nutritional strategy in the treatment of NAFLD, the investigators proposed a randomized controlled trial evaluating the effects of a hypocaloric high-protein diet and aerobic exercise associated with this diet on metabolic and anthropometric parameters in sedentary postmenopausal women. 40 sedentary postmenopausal women with NAFLD who had liver biopsy for a period equal to or less than 2 two years were included. These patients were randomized into 2 groups: TRAINING group 19: aerobic training with hypocaloric high-protein diet and DIET group 21: only hypocaloric high-protein diet, and followed for a period of six months.
