Abstract

Background: The prevalence of metabolic associated fatty liver disease (MAFLD) is high. However, there are few studies on the effects of time-restricted feeding (TRF) and caloric restriction (CR) in MAFLD.

Objectives: To investigate the efficacy and mechanism of 4 h TRF and 60% CR in MAFLD.

Methods: Twelve male Sprague-Dawley rats were randomly assigned to the Normal group (normal diet, 10 kcal% fat), while the remaining 38 rats were assigned to the MAFLD group (high-fat diet, 60 kcal% fat). 10 weeks later, the MAFLD group was randomly divided into the 4 h TRF, 60% CR, 4 h TRF + 60% CR, and Model groups; all rats were then given normal diet. After 4 weeks, weight, blood lipid, and other indicators were detected.

Results: After the high-fat diet was discontinued, the liver lipid levels in the rat with MAFLD significantly reduced, while the body weight was not significantly changed. The rats in the Model group were heavier than those in the other four groups (p < 0.01). The triglyceride levels were higher in the TRF + CR group compared with the Model group (p < 0.01). Compared with the Model group, 110 metabolites were decreased in the TRF + CR group, and 83 metabolites were elevated in liver. Kyoto Encyclopedia of Genes and Genomes revealed that the mechanism involved the proliferator-activated receptor alpha signaling pathway, metabolic pathway, and so on. We observed differences in silent information regulator transcript 1 (SIRT1) mRNA levels in all five groups (p = 0.003).

Conclusions: 4 h TRF and 60% CR significantly reduced body weight and liver lipid in rats with MAFLD. 4 h TRF can improve MAFLD, and there is no need to excessively restrict food intake.

期刊介绍： Nutrition & Metabolism publishes studies with a clear focus on nutrition and metabolism with applications ranging from nutrition needs, exercise physiology, clinical and population studies, as well as the underlying mechanisms in these aspects. The areas of interest for Nutrition & Metabolism encompass studies in molecular nutrition in the context of obesity, diabetes, lipedemias, metabolic syndrome and exercise physiology. Manuscripts related to molecular, cellular and human metabolism, nutrient sensing and nutrient–gene interactions are also in interest, as are submissions that have employed new and innovative strategies like metabolomics/lipidomics or other omic-based biomarkers to predict nutritional status and metabolic diseases. Key areas we wish to encourage submissions from include: -how diet and specific nutrients interact with genes, proteins or metabolites to influence metabolic phenotypes and disease outcomes; -the role of epigenetic factors and the microbiome in the pathogenesis of metabolic diseases and their influence on metabolic responses to diet and food components; -how diet and other environmental factors affect epigenetics and microbiota; the extent to which genetic and nongenetic factors modify personal metabolic responses to diet and food compositions and the mechanisms involved; -how specific biologic networks and nutrient sensing mechanisms attribute to metabolic variability.
