Nonalcoholic fatty liver disease (NAFLD) is associated with a 2- to 3-fold increase in the risk of developing type 2 diabetes (T2DM) in non-diabetic patients, and therefore, the NAFLD population is considered a large population at a high risk of T2DM. In the population diagnosed with T2DM, the prevalence rate of NAFLD reaches as high as 60%-80%. T2DM is considered a lifelong disease in the traditional view, but recently, more and more evidence supports that T2DM can be reversed, which brings new light to the prevention and treatment of T2DM. The remission of T2DM depends on the appropriate treatment methods and timing. The liver plays a key role in glucose and lipid metabolism, and excessive fat accumulation in the liver may induce insulin resistance, increased production of hepatic glucose, and increased triglyceride export, which further leads to fat deposition in the pancreas and beta-cell injury and eventually causes the onset of T2DM. Lifestyle intervention can reduce liver fat content and achieve the remission or reversal of diabetes, and NAFLD can be regarded as an “early warning window” for T2DM. Therefore, the treatment regimen aiming at improving liver fat content may become a good strategy to prevent and reverse diabetes.
