Current pharmacotherapies such as orlistat and metformin show clear efficacy but are associated with long-term tolerability concerns. This study aimed to evaluate whether the next-generation probiotic candidate\n                      <jats:italic>Phocaeicola dorei<\/jats:italic>\n                      YGMCC0564 attenuates HFD-induced glycolipid metabolic disturbances in mice. We hypothesized that the protective effect of YGMCC0564 would be associated with modulation of bile acid metabolism and may be partly mediated by it.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A high-fat diet (HFD)-induced mouse model of glycolipid metabolic disturbance was used, with YGMCC0564 supplementation initiated concurrently with HFD feeding in a prevention design.\n                      <jats:italic>Lactobacillus rhamnosus<\/jats:italic>\n                      GG and orlistat served as reference controls. Efficacy was assessed by body composition, histopathology, biochemical assays, and quantitative PCR, combined with 16S rRNA gene sequencing, non-targeted metabolomics, targeted quantification of fecal short-chain fatty acids, and cell-based functional assays. Safety was evaluated in acute and 4-week subchronic tests in immunodeficient and normal mice.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      YGMCC0564 attenuated HFD-induced body weight gain, dyslipidemia, and hyperglycemia, reduced hepatic steatosis and gluconeogenic gene expression, and improved insulin resistance. Multi-omics analysis showed that YGMCC0564 reshaped the gut microbiota and restored fecal short-chain fatty acid concentrations that had been reduced by HFD feeding. The fecal bile acid profile was remodeled, with elevated lithocholic acid (LCA) and 3\u03b2,7\u03b1-dihydroxy-5-cholestenoate and reduced \u03b1-muricholic acid (\u03b1-MCA), chenodeoxycholic acid (CDCA), taurodeoxycholic acid (TDCA), and isoLCA. Intestinal expression of Fxr, Fgf15, Gpbar1\/Tgr5, and Glp-1 was upregulated, consistent with enhanced bile acid receptor signaling.\n                      <jats:italic>In vitro<\/jats:italic>\n                      , a 1:1 mixture of LCA and 3\u03b2,7\u03b1-dihydroxy-5-cholestenoate, the two bile acids elevated by YGMCC0564\n                      <jats:italic>in vivo<\/jats:italic>\n                      , activated FXR-FGF19 signaling in HT-29 intestinal cells and suppressed gluconeogenic gene expression and glucose output in HepG2 cells.
