Abstract

Garlic (Allium sativum L.) has long been used as a medicinal food. Indeed, garlic and its constituents have been shown to possess potent regulatory activities in bodily functions, including blood coagulation, lipid metabolism, immunity and xenobiotic metabolism. In this study, we aimed to examine the anti‑obesity effects of garlic oil and to elucidate the possible underlying mechanisms. For this purpose, garlic oil (GO; 80 mg/kg body weight, p.o.) or corn oil alone as a vehicle‑control were administered to male Sprague‑Dawley rats every other day for 10 weeks. The results revealed that GO administration significantly reduced body weight gain and white adipose tissue (WAT) mass, which had been increased by feeding on the AIN‑76‑based high‑fat diet (60% kcal fat). Expired gas analysis was performed at 9 weeks following the GO administration to calculate fuel oxidation. GO administration enhanced O2 consumption during the dark period (at night) and increased energy expenditure through fat oxidation during the light period (daytime); however, carbohydrate oxidation remained unaltered. Western blot analysis revealed that GO administration increased UCP1 protein expression in brown adipose tissue (BAT). On the whole, the findings of this study indicated that GO suppressed body weight gain and WAT mass in the rat model of high‑fat diet‑induced obesity by increasing UCP1 expression and by enhancing fat oxidation and energy expenditure.
