Mediterranean Lifestyle Intervention in Patients With Non-alcoholic Fatty Liver Disease
Non-alcoholic fatty liver disease (NAFLD) is considered as the hepatic manifestation of the metabolic syndrome. NAFLD is a pathologic condition which involves both hepatic steatosis and non alcoholic steatohepatitis (NASH), as the result of fat accumulation in the liver (liver fat >5-10% of liver weight), not due to excess alcohol consumption or other causes of steatosis.
At present, no medication or surgical procedure has been approved for treating NAFLD and lifestyle modifications remain the cornerstone therapy targeting both at weight reduction for overweight subjects and at prevention of overweight for the normal weight individuals. Given that a Mediterranean dietary pattern has a beneficial effect both on the prevention and the resolution of the metabolic syndrome, the main aim of the present study is to implement and evaluate the potential benefits of an intervention based on the Mediterranean lifestyle in a sample of patients with NAFLD.

|Official Title:||Effect of a Mediterranean Lifestyle Intervention on Biochemical and Clinical Characteristics of Patients With Non-alcoholic Fatty Liver Disease.|
- Serum levels of alanine aminotransferase (ALT) [ Time Frame: Within 6 months ]Clinically useful reduction in ALT, defined as the restoration of ALT within normal limits or reduction of ALT in >50% of its initial value.
- Gamma-glutamyl transpeptidase (GGT) [ Time Frame: Within 6 months ]Restore of GGT levels within normal limits (i.e. GGT<30 IU/L).
- Liver stiffness [ Time Frame: Within 6 months ]Improved liver stiffness as estimated with elastography.
- Inflammatory and oxidative stress markers [ Time Frame: Within 6 months ]Improved inflammatory markers (TNF-a, IL-6, IL-8, adiponectin) and oxidative stress markers (ex vivo serum resistance to oxidation, measurement of the compounds that react with thiobarbituric acid-TBARS, activity of glutathione peroxidase) as well as lipid/glucose metabolism improvement (triglycerides, HDL, LDL, total cholesterol, insulin resistance index).

No Intervention: Control Group
This arm will receive written general advice for a healthy lifestyle.
Experimental: Mediterranean Diet Group
Mediterranean Diet Group participants will attend a comprehensive program,focusing on Mediterranean diet, comprising of seven 60-min group counseling sessions, conducted every two weeks for the first 2 months and every month for the following 4 months, until the 6-month evaluation.
Behavioral: Mediterranean Diet
Counseling will be based on the goal setting theory. Motivational and behavioral strategies will be also used. In the Mediterranean diet group, all food groups of the Mediterranean diet will be targeted.
Experimental: Mediterranean Lifestyle Group
Mediterranean Lifestyle Group participants will attend a comprehensive program,focusing on Mediterranean lifestyle, comprising of seven 60-min group counseling sessions, conducted every two weeks for the first 2 months and every month for the following 4 months, until the 6-month evaluation.
Behavioral: Mediterranean lifestyle
Counseling will be based on the goal setting theory. Motivational and behavioral strategies will be also used. In the Mediterranean lifestyle group culinary practices, seasonality, and locality of food products, socialization during meals, rest during the day, as well as the adoption of an active living will be additionally addressed.
