The original Grapefruit Diet, is an unhealthy, ultra low calorie plan, and not recommended. However, a 2004 study led by Dr. Ken Fujioka at the Nutrition and Metabolic Research Centre at Scripps Clinic found that simply adding half a grapefruit or a serving of grapefruit juice to each meal resulted in an average weight loss of around 3.5 pounds over 12 weeks.
