Grapefruit essential oil can stop your body from retaining water, which is one of the main causes of bloating, and can also dissolve fat in the body. The essential oil does this by releasing the stored fat into the bloodstream so your body can dissolve and absorb it and turn it into energy. Grapefruit essential oil can also be a strong suppressant for your cravings. It can help you feel full for long. Put a few drops of the grapefruit essential oil into your diffuser or inhaler to stop any hunger pangs from making you reach for another doughnut!
