Well The Mayo Clinic Grapefruit Diet is a good example of how people attempt to put a famous name on a diet plan to give it credibility. There is no such thing as the Mayo Clinic Grapefruit Diet. The Mayo Clinic name was just attached to a old fashioned grapefruit diet to make it more credible. The Mayo Clinic denies any connection to the diet that is often labeled The Mayo Clinic Grapefruit Diet. Not only does the Mayo Clinic not endorse the diet they consider it unbalanced and dangerous.

Mayo Clinic Grapefruit Diet is called so by error and more correctly called mayo grapefruit diet, mayo being for mayonnaise
