Grapefruit diet facts for kids
The Grapefruit diet (also known as the Hollywood diet and the 18-Day diet) is a short-term fad diet that has existed in the United States since at least the 1930s. There are variations on the diet, although it generally consists of eating one grapefruit at each meal, along with meat, eggs, other foods that are rich in fat and protein, and certain vegetables. Sugar, fruits (other than grapefruit), sweet vegetables, grains and starchy vegetables are to be avoided. The grapefruit diet is thus a low-carbohydrate diet. A typical breakfast menu usually includes bacon and eggs. The diet is based on the claim that grapefruit has a fat-burning enzyme or similar property. The grapefruit diet does not require exercise. The grapefruit diet lasts for 10 to 12 days followed by 2 days off.
History
The grapefruit diet originated in the 1930s. It was originally known in 1929 as the "eighteen-day diet", and featured 18 days of grapefruit, orange, toast, vegetable and egg combinations, totalling approximately 500 kilocalories (2,100 kJ). The originator of the diet is not known. One rumour traces the diet to actress Ethel Barrymore, who is alleged to have paid William James Mayo and his brother 500 dollars (equivalent to $9,000 in 2022) to create a special diet for her. The diet then became a fad in Hollywood and spread throughout America. The Mayo Clinic has disavowed the grapefruit diet.
Novelist Fannie Hurst was a notable devotee of the diet. It was re-popularized in the 1980s and nicknamed the "10-day, 10-pounds-off diet". The idea that grapefruit eaten before a meal acts as a "catalyst" to burn body fat has no evidence from biochemistry.
