Previous studies have reported on the glucose and lipid-lowering effects of ferulic acid (FA) but its anti-obesity potential has not yet been fi rmly established. This study investigated the possible anti-obesitogenic effects of FA in mice fed a high-fat diet (HFD) for 15 weeks. To assess the antiobesity potential of FA, 32 male Swiss mice, weighing 20 – 25 g (n=6 – 8 per group) were fed a normal diet (ND) or HFD, treated orally or not with either FA (10 mg/kg) or sibutramine (10 mg/kg) for 15 weeks and at the end of this period, the body weights of animals, visceral fat accumulation, plasma levels of glucose and insulin hormone, amylase and lipase activities, the satiety hormones ghrelin and leptin, and tumor necrosis factor- a (TNF- a ) and monocyte chemoattractant protein-1 (MCH-1) were analyzed. Results revealed that FA could effectively suppress the HFD-associated increase in visceral fat accumulation, adipocyte size and body weight gain, similar to sibutramine, the positive control. FA also signi fi cantly (P o 0.05) decreased the HFD-induced elevations in serum lipid pro fi les, amylase and lipase activities, and the levels of blood glucose and insulin hormone. The markedly elevated leptin and decreased ghrelin levels seen in HFD-fed control mice were signi fi cantly (P o 0.05) reversed by FA treatment, almost reaching the values seen in ND-fed mice. Furthermore, FA demon- strated signi fi cant (P o 0.05) inhibition of serum levels of in fl ammatory mediators TNF- a , and MCH-1. These results suggest that FA could be bene fi cial in lowering the risk of HFD-induced obesity via modulation of enzymatic, hormonal and in fl ammatory responses
