    Preliminary studies in animals show that the scent of grapefruit oil—yes, just the scent—has an effect of reducing the appetite and body weight (rats exposed to the scents for 15 minutes three times a week enjoyed the effect).

    The cause? It's unclear, but it may work through grapefruit oil's effects on liver enzymes. Grapefruit oil is widely available through aromatherapy stores and web sites. As a bonus, try to eat a couple of grapefruits while you're searching.
