Crazy fad diets go back a long way. Here’s what some stars of old Hollywood did when they wanted to drop a few pounds.

Marilyn Monroe

Two raw eggs whipped in warm milk for breakfast, no lunch, and for dinner broiled liver, steak, or lamb, and five carrots.

Jean Harlow

She occasionally went on “The Four-Day Diet.” For four days she ate only two tomatoes for lunch (with black coffee), and then the same thing at dinner.

Nita Naldi

The silent film star popularized the “Lamb Chop and Pineapple Plan” in 1924. For breakfast she ate two slices of pineapple; for lunch, a lamb chop and a slice of pineapple; dinner was two lamb chops and two slices of pineapple.

Betty Grable

She’d snack on raw onions and garlic.

Gloria Swanson

She had a recipe for “Double Corn Soup,” consisting of chopped onions, water, a few drops of olive oil, soy sauce, and half a cup of corn meal.

Elizabeth Taylor

Taylor would diet six days out of the week, eating little more than dried toast. The seventh day was her “pig-out day,” and she would indulge in her favorite snack: sour cream mixed with cottage cheese.

Joan Crawford

A few spoonfuls of cold beef consommé and six crackers with mustard.

Grace Kelly

Oatmeal for breakfast, and then as many carrot sticks and celery as she wanted, provided she ate them by 11:00 a.m.

Orson Welles

To drop the 50 pounds he gained to play the lead role in Citizen Kane, for a month he ate only orange juice, salad (without salad dressing), and boiled eggs.

Maria Callas

The opera star had a doctor inject iodine into her thyroid to “speed up her metabolism.”

Jacqueline Kennedy

She wasn’t a Hollywood movie star, but she was just as famous and influential. Her diet secret: her one daily meal would be a baked potato, topped with caviar.
