The cornerstone of any treatment regimen for patients with NAFLD is lifestyle modification focused on dietary changes and physical activity. The main objective of our study was to outline the effect of diet and lifestyle factors on the development of NAFLD.

Second, we used a synergistic DUAL murine model of NAFLD and alcohol consumption to study the biological impact of physical exercise and dietary changes on the regression of steatohepatitis and fibrosis. Finally, we confirmed our finding in an alternative animal model, zebrafish (Danio rerio)...
