Research advances in dietary intervention in the treatment of metabolic associated fatty liver disease

Poor dietary habit is an important cause of the global prevalence of metabolic associated fatty liver disease (MAFLD), and the adjustment of dietary pattern is the cornerstone of MAFLD management. In recent years, a large number of new dietary intervention methods have been proposed and applied in the treatment of MAFLD, including calorie restrict diet, low-carbohydrate diet, low-glycemic index diet, low free sugar diet, intermittent fasting pattern, high protein diet, and Mediterranean diet, and these new methods have different effects in clinical practice. This article introduces the treatment concepts and practical methods of these new dietary treatment strategies and the evidence of their benefits in the treatment of MAFLD in China and globally, so as to provide a new perspective for clinicians to guide patients to achieve individualized nutritional therapy.
