Although preliminary evidence suggests that intermittent fasting mimic-diet (IFD) exerts stronger effects on body weight and metabolic parameters, which may link obesity, non-alcoholic fatty liver disease (NAFLD) and major chronic diseases, compared with continuous calorie restriction (CCR), there is a lack of well-powered intervention studies. This randomized controlled trial will test whether IFD, operationalized as the "5:2 diet," has stronger effects on anthropometric and body composition characteristics, and circulating metabolic biomarkers than CCR and a control regimen in adults with NAFLD.

Inclusion Criteria:

• The diagnosed criteria of fatty liver by ultrasound were presence of two of the three following criteria: increased hepatic echogenicity compared with cortical of the right kidney, blurring of liver vasculature, and deep attenuation of the ultrasonographic signal.

Exclusion Criteria:

• Excessive alcohol consumption (ethanol > 140 g/wk for men and > 70 g/wk for women), cirrhosis, viral hepatitis, cardiovascular disease, cancer, any consumption of nonsteroidal anti-inflammatory drugs, corticosteroids or prescriptive medicine that affect liver function, lipid and glucose metabolism.
