Non-alcoholic fatty liver disease, a chronic metabolic disease, has been studied for decades. There is already well-recognized pathogenesis from pathology, epidemiology, physiology, gene expression, etc. While the understanding of the disease itself is increasing, therapies for this issue seem to have some obstacles: there has been no officially accepted direct pharmaceutical treatment(targeted drugs) until now. Nevertheless, lifestyle regulation has been investigated a lot to fill in this gap. Many researches have already given recommendations in fields of diets or physical activities. However, there is a lack of a comprehensive review to combine both perspectives and give an overview of the disease. This article will review the researches on the lifestyle recommendations for NAFLD patients from both diet and exercise aspects. All the references throughout this research, including journals and literature reviews, are conducted from online databases. The content will mainly discuss the effectiveness of different types of diet and how exercise taking place with respect to reducing the NAFLD risk factors. In brief, most current experimental/observational results suggest that a Mediterranean diet combining with moderate intense exercise could be remarkably beneficial in the management of NAFLD.
