Welcome to the Mayo Clinic Diet that doesn't come from the Mayo Clinic. This diet is a strange idea that has been floating around for a long time, despite the fact that it is not endorsed by the Mayo Clinic. Once again dieters are face to face with the misleading idea that somehow grapefruit burns fat, which leaves the dieter free to indulge in high fat food like ham and eggs for breakfast and meat, vegetables and salad dressing for lunch and dinner. This is not a diet, but a dream come true! Or, at least, it would be a dream if it actually worked.
