Hay diet

An eclectic diet described by William Howard Hay, an American doctor, in which major food groups are eaten in separate sessions. For example: carbohydrates are not consumed within four hours of ingesting proteins and acidic fruits; refined and processed foods are forbidden; alcoholic beverages are allowed, but differ according to whether one is ingesting a “carbohydrate” or a protein meal. Anecdotal reports suggest that the diet may promote health and a sense of well-being, and may be useful for treating arthritis, constipation, diabetes, heart disease, hypertension, indigestion, obesity and (peptic) ulcers.

It is not based on any established scientific principles.
