Key points

The purpose of this study was to evaluate the combined effects of puerarin (Pue) and insoluble dietary fiber from Hericium erinaceus (HEIDF) on obesity induced by a high-fat diet (HFD) in mice, focusing on their effects on lipid and glucose metabolism, gut microbiota (GM), and serum metabolites
Glucose tolerance, tissue pathology, and serum biochemical levels were conducted to assess the effects of puerarin combined with Hericium Erinaceus insoluble dietary fiber (LH) on glucose and lipid metabolism. 16S rRNA sequencing and untargeted metabonomics were employed to explore the underlying mechanisms
The results showed that the LH group significantly reduced body weight and hepatic and adipose lipid accumulation, and improved glucose tolerance and dyslipidemia compared to the Pue or HEIDF groups alone
Moreover, the LH group exhibited enhanced regulation of GM, including increased microbial diversity, higher abundance of beneficial bacteria such as g__Lactobacillus and g__Bacillus, and a decreased Firmicutes-to-Bacteroidota ratio
The combination of Pue and HEIDF exhibits a synergistic anti-obesity effect by modulating specific GM (g__Lactobacillus and g__Bacillus) and serum metabolites.IMPORTANCEThe combination of HEIDF and Pue holds significant importance in the context of obesity
This synergistic effect not only aids in weight management but may also enhance metabolic health through various mechanisms, including increased satiety and promotion of fat oxidation

The purpose of this study was to evaluate the combined effects of puerarin (Pue) and insoluble dietary fiber from Hericium erinaceus (HEIDF) on obesity induced by a high-fat diet (HFD) in mice, focusing on their effects on lipid and glucose metabolism, gut microbiota (GM), and serum metabolites. Glucose tolerance, tissue pathology, and serum biochemical levels were conducted to assess the effects of puerarin combined with Hericium Erinaceus insoluble dietary fiber (LH) on glucose and lipid metabolism. 16S rRNA sequencing and untargeted metabonomics were employed to explore the underlying mechanisms. The results showed that the LH group significantly reduced body weight and hepatic and adipose lipid accumulation, and improved glucose tolerance and dyslipidemia compared to the Pue or HEIDF groups alone. Moreover, the LH group exhibited enhanced regulation of GM, including increased microbial diversity, higher abundance of beneficial bacteria such as g__Lactobacillus and g__Bacillus, and a decreased Firmicutes-to-Bacteroidota ratio. In addition, the LH group ameliorated HFD-induced serum metabolite changes and promoted the activation of tryptophan and glycerophospholipid metabolism pathways. The combination of Pue and HEIDF exhibits a synergistic anti-obesity effect by modulating specific GM (g__Lactobacillus and g__Bacillus) and serum metabolites.IMPORTANCEThe combination of HEIDF and Pue holds significant importance in the context of obesity. This synergistic effect not only aids in weight management but may also enhance metabolic health through various mechanisms, including increased satiety and promotion of fat oxidation. Therefore, incorporating these two components into the daily diet could offer effective strategies for the prevention and intervention of obesity and its related diseases.
