Polysaccharide from Enteromorpha prolifera (EPP) has therapeutic and nutraceutical potential for obesity management due to its high hypolipidaemic activity. However, the metabolic mechanism by which EPP mediates anti-adiposity effects are not fully understood. This study aimed to evaluate the effects of EPP on insulin signaling and adaptive thermogenesis in high-fat diet (HFD)-fed obese mice, and further explore the underlying mechanisms. C57BL/6 male mice were fed a control diet or an HFD diet with or without 5% EPP for 12 weeks. The insulin signaling and thermogenic program in adipose tissue, and energy expenditure, as well as involvement of PPARÎ³ coactivator-1Î± (PGC-1Î±)-fibronectin type 3 domain-containing protein 5 (FNDC5)/irisin pathway were assessed. EPP alleviated diet-induced adiposity, and decreased inflammatory response and improved insulin signaling in white adipose tissue (WAT) of HFD mice. Moreover, EPP administration increased oxygen consumption, carbon dioxide production and heat production in HFD mice, as reflected by the increased thermogenesis...
