This study tested the anti-obesity and hypolipidemic effects of red garlic extract in obese rats induced by a high fat diet over a period of 4 weeks. Red garlic extract of 15 brix was added in 1, 3, 5 and 7% ratios in diets. The obesity index and body fat content significantly decreased in rats fed a diet with over 3% red garlic extract compared to the control group. There was no significant difference in weight of visceral and epididymal fat in rats fed red garlic extract. Total lipid and triglyceride levels in serum were significantly decreased in a dose-dependent manner, and AI and CRF also fell. ALT and AST activities in groups fed red garlic extract were decreased compared to the control group. Total lipid level in liver tissue of the groups fed 5-7% red garlic extract exhibited a significant decrease compared to the control group. Total cholesterol and triglyceride levels in feces were significantly increased in rats fed a diet with over 5% red garlic extract. Lipid peroxide levels were significantly decreased in the groups fed diets with 5-7% red garlic and antioxidant activity in serum was significantly increased in the group fed a diet with 7% red garlic extract compared to the control group. Our results suggest that red garlic extract could have anti-obesity and hypolipidemic effects for suppressing obesity index and decreasing lipid profiles.
