Influence of a Mediterranean Diet Combined With a Physical Activity Intervention, on NAFLD and Inflammation Parameters.

The study in question is an interventional study with nutritional intervention. The aim of the study is to evaluate whether the adoption of two different models of Mediterranean Diet, based on the different percentage of carbohydrates and lipids, associated with a program of moderate intensity aerobic physical exercise, in patients with obesity and NAFLD can exercise, after only 3 months, effects on: * specific aspects associated with NAFLD, such as the degree of hepatic steatosis and fibrosis; * circulating levels of molecules correlated with the degree of generalized and hepatic inflammation and the blood concentrations of metabolic and cardiovascular risk factors associated with abdominal obesity; * intestinal barrier; * body composition; * intestinal microbiota; * symptoms of IBS (irritable bowel syndrome) in patients with NAFLD.
