The effects of the olfactory stimulation with scent of grapefruit essential oil on the body weight, the food intake, and the concentration of plasma glycerol in mice were studied. When the olfactory stimulation with scent of grapefruit essential oil was given to mice for 3 times per week for three weeks, the treatment at a dose of 200 μL tended to suppress the increase of body weight and the food intake than the treatment at a dose of 50 μL. However, the concentration of plasma glycerol in mice as an index of lipolysis tended to be high at a dose of 50 μL. When the amount of treatment with grapefruit essential oil was kept constant with 200 μL, the four treatments with 50 μL tended to suppress the increase of body weight and the food intake in mice than the single treatment with 200 μL. Moreover, the concentration of plasma glycerol in mice tended to be high in the four treatments with 50 μL. These results suggest that the olfactory stimulation with scent of grapefruit essential oil would suppress the body weight and the food intake, and enhance lipolysis in mice.
