There are examples throughout history of eccentrics living on monotrophic diets. For example,
George Sitwell ate only roasted chicken.
Howard Hughes would sometimes spend weeks eating nothing but
canned soup and at other times only steak sandwiches.
Monotrophic diets ;Beef A stricter type of
carnivore diet known as the lion diet or all meat diet that has been promoted by
Jordan Peterson involves only consuming beef with salt and water. ;Eggs
Piero di Cosimo, an Italian painter, ate only
boiled eggs.
Antonio Magliabechi's diet was commonly three hard-boiled eggs. In 2008, it was reported that
Charles Saatchi lost four stone (56 pounds) from an egg-only diet for nine months. However, the claim that he ate only eggs for this period of time was disputed. He advertised the diet as a remedy for diverse ailments such as
eczema,
hay fever and
impotence. ;Potatoes In 2010, Chris Voigt, executive director of the Washington State Potato Commission, ate twenty potatoes a day for two months. He accepted that the diet is not sustainable in the long term but said his experiment had revealed how "truly healthy" potatoes are. In 2016, comedian and magician
Penn Jillette began his weight loss regimen with a mono diet, eating only potatoes for two weeks, then adding in other healthy foods to change his eating habits. ==Health concerns==
