Honeysuckle anthocyanin supplementation prevents diet-induced obesity in C57BL/6 mice

Abstract

This study investigated the anti-obesity effects of honeysuckle anthocyanins (HA) in a high fat diet-induced mouse model. The mice were initially fed with a low-fat diet (LFD) or high-fat diet (HFD) for 8 weeks. After that, the HFD-fed mice were divided into five groups, with 12 mice in each group, including a HFD group, a HFD plus Orlistat group, and three HFD plus HA (at a dose of 50, 100, or 200 mg kg(-1)) groups, for another 8-week experiment. HA at 100 or 200 mg kg(-1) can suppress body weight gain, reduce serum and liver lipid profiles, ameliorate impaired hepatic function, and significantly increase serum adiponectin concentration while decreasing serum insulin and leptin levels. These results suggest that the anti-obesity effect of HA might be through the blockage of lipid accumulation.
