Mayo Clinic Diet

The Mayo Clinic Diet is sometimes used as a name for a diet plan based mainly on eggs, meat and grapefruit. Claims for it include that it is used on cardiac wards for patients needing to lose weight quickly, and that the grapefruit acts as catalyst to burn fat. However this diet is high in cholesterol and saturated fat. The British Heart Foundation and American Heart Association (among others) warn that these can cause heart problems.

The Mayo Clinic refers to it as a myth and advises people not to follow it.
