Abstract

The aim of the present study was to investigate the anti-obesity effect of a mixture composed of Garcinia cambogia extract, soypeptide, and L-carnitine (1.2:0.3:0.02, w/w/w) in rats rendered obese by a high-fat diet (HFD). Sprague-Dawley rats were fed either the high-fat control diet (CD) or the 0.38% mixture-supplemented HFD (CD + M) for 9 weeks. The mixture significantly reduced body weight gain and the accumulation of visceral fat mass in a rat model of HFD-induced obesity. Moreover, the mixture effectively lowered blood and hepatic lipid concentrations and serum glucose, insulin, c-peptide, and leptin levels in rats with HFD-induced obesity. Results from real-time reverse transcription-polymerase chain reaction analyses indicated that the expression levels of leptin, tumor necrosis factor-alpha (TNF-α), and sterol regulatory element binding protein Ic (SREBP1c) genes in the epididymal fat tissue of rats fed the CD + M diet were 0.4-, 0.6-, and 0.48-fold, respectively, of those found in the CD rats (P < 0.05), while expression of the uncoupling protein 2 (UCP2) gene in epididymal adipose tissue was 1.25-fold (P < 0.05) of that found in CD rats. In conclusion, a mixture composed of G. cambogia extract, soy peptide, and L-carnitine attenuated visceral fat accumulation and improved dyslipidemia in a rat model with HFD-induced obesity.
