Abstract Pueraria lobata resistant starch (PLRS) is prepared by modifying Pueraria lobata starch with pullulanase, and the PLRS modulate lipid metabolism disorders and gut microbiota structure are hypothesized in high‐fat diet (HFD) mice. The results reveal that the PLRS can alleviate lipid metabolism disorders by significantly upregulating the abundance of Akkermansia , Lactobacillus , Blautia , and Dubosiella , but markedly downregulating Staphylococcus in HFD mice. The PLRS may decrease the gain of weight, biochemical index, ameliorate hepatic impairment, and histopathological. Molecular mechanisms have elucidated that the PLRS may exert reducing fat accumulation and stabilize the gut microbiota effects through the modulation of the fatty acid metabolic signaling pathway and the PPAR signaling pathway. Therefore, these results suggest that this prebiotic carbohydrate may regulate lipid metabolism and gut microbiota in HFD mice and can be used to prepare healthy lipid‐lowering functional foods to attenuate obesity problems.
