Grapfruit is now heralded as a waist whittling miracle food. Why? Scientists have discovered it's rich in naringin, which blocks the absorption of dietary carbs and prevents up to 30% of excess calories from being stored in fat cells. They have found adding 1/2 a grapefruit to 3 meals daily delivered a 10 pound loss in 12 weeks! Bring on the grapefruit! Adapted from First magazine.
