Anti-obesity effects of kimchi tablet composition (KTC) were investigated with male Sprague-Dawley rats fed high-fat diet for 8 weeks. Fifty rats were classified to 4 groups: normal diet (ND), high fat diet (HFD), HFD + KTC 5% and HFD + KTC 10% for feeding experiments. This research showed that the final weight, weight gain, food efficiency ratio and organ weight were decreased by the addition of KTC compared to those of HFD group. Amount of subcutaneous fat of KTC groups were 13.6% and 21.3%, respectively. The plasma triglyceride concentration of KTC groups was lower than that of high fat diet group. Plasma cholesterol concentration of all four groups were not significantly different. HDL-cholesterol concentration of KTC groups was higher than those of high fat diet group. In addition, triglyceride and cholesterol concentrations in the liver and heart were reduced by the addition of KTC. Moreover, triglyceride concentration of fecal and hepatic HMG-CoA reductase activity were increased in KTC group. These results suggested that KTC might be useful for obesity control and good source of functional kimchi tablet.
