[Nonalcoholic Fatty Liver Disease and Weight Loss].

Nonalcoholic fatty liver disease(NAFLD)refers to hepatic steatosis without other known causes such as alcohol abuse or hepatic virus infection. NAFLD has become a chronic disease worldwide,and its prevalence is constantly growing. Hepatic insulin resistance caused by obesity results in the deposition of triglycerides in the liver,promoting the occurrence and development of NAFLD. Weight loss is the only safe and effective method for NAFLD. Lifestyle intervention plays a cornerstone role in treating NAFLD;however,most patients can not achieve and maintain the ideal body weight by lifestyle intervention alone. Glucagon-like peptide-1 receptor agonist and metabolic surgery are promising treatments for NAFLD.
