During 8\u2009weeks, the food intake and body weight of the mice were monitored. Subsequently, an oral glucose tolerance test (OGTT) was conducted, and fasting insulin levels, lipid profiles, and the gut microbiota composition were determined. Liver lesions, inflammation levels, and tight junction protein expression were examined using Oil Red O staining, haematoxylin and eosin staining, and reverse transcription polymerase chain reaction analysis, respectively. 16s rRNA high\u2010throughput sequencing techniques were used to investigate the diversity and richness of the gut microbiota.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      BBr60 not only ameliorated HFD\u2010induced metabolic disorders, including weight gain (body weight,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), hyperglycaemia (FBG,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), insulin resistance (HOMA\u2010IR,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002), dyslipidaemia (TC,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), and liver steatosis, but also mitigated systemic inflammation and impaired intestinal permeability.
