This study demonstrates that Lactobacillus paracasei 24 (LP24) can alleviate lipid accumulation in an obese mouse model induced by a high-fat diet. The alleviating effect is achieved through improving blood lipid levels and liver health by regulating the gut microbiota.
: Obesity has become a worldwide public health problem. Lactic acid bacteria have attracted extensive attention for alleviating obesity and fat accumulation. This study aimed to evaluate the alleviating effects of Lactobacillus paracasei 24 (LP24) on lipid accumulation in an obese mouse model induced by a high-fat diet (HFD). The results showed that LP24 treatment significantly reduced body weight and fat deposition in HFD mice, improved blood lipid levels and liver steatosis, reduced liver oxidative stress injury and the inflammatory response, and regulated fat metabolism-related factors. Moreover, LP24 regulated the abundance and diversity of the gut microbiota, reduced the abundance of Firmicutes and the ratio of Firmicutes/Bacteroidetes (F/B), and increased the abundance of Akkermansia. In summary, LP24 regulates lipid metabolism by activating the expression level of related genes and regulating the gut microbiota through the gut-liver axis to attenuate the development of obesity. This study provides a theoretical basis for probiotics to regulate gut microbiota to reduce lipid accumulation
