Dietary crude propolis (0.2% over 2 or 5 weeks)  HFD-induced muscle wasting in male C57BL/6 mice (4-weeks old)  EG: propolis + HFDCG1: HFD onlyCG2: untreated mice  16S rRNA of gut microbiota, serum levels of LPS, triacylglycerols and glucose, and skeletal muscle levels of inflammatory cytokine TLR4 expression.  Propolis (5 weeks) significantly decreased serum triacylglycerols, glucose, circulating LPS and down-regulated the expression TLR4 and inflammatory cytokine in muscle. It countereacted the effect of HFD on gut microbiota.  [116]
