GRAPEFRUIT

Grapefruit can be a great weight loss food. It contains phytochemicals that reduce insulin levels and help to convert calories into energy instead of fat. A study at the Scripps Clinic found that subjects who either ate half a grapefruit or drank an 8 ounce glass of juice before each meal lost more weight than the control group. Grapefruit can have a harmful interaction with certain medications, so check with your doctor before incorporating the fruit into your diet.
