Grapefruit! The grapefruit diet is not a myth. Researchers at Scripps Clinic found that participants who ate half a grapefruit with each meal in a 12-week period lost an average of 3.6 pounds. The study indicates that the unique chemical properties in this vitamin C-packed citrus fruit reduce insulin levels, which promotes weight loss and boost metabolism. NOTE: If you are taking medication, check with your doctor about any potentially adverse interactions with grapefruit. Grapefruit, because of the soft peel is a nice alternative to an apple of orange and study after study of the last 30 years has shown that it can really help burn fat.
