The Cambridge Diet is a fad diet in which 600 to 1500 kcal are consumed per day, principally in liquids made from commercial products sold as part of the diet regime.[1] These products are manufactured in the UK and include shakes, meal replacement bars, soups and smoothies.

Development and Reception

The Cambridge Diet was developed in 1970 by Dr. Alan Howard at Cambridge University, England. It was launched as a commercial product in the United States in 1980. The Diet was very popular in America but was also the subject of some controversy.[2] It later came under scrutiny from regulators and health authorities after potential health concerns were raised.[3] In the UK, the Cambridge Diet was launched in 1984. In 1986 the Diet was reformulated to adhere to recommendations made by the Commission on Medical Aspects (COMA)[4]

The Cambridge Diet is categorized as a very-low-calorie diet, starting as low as 415 calories/day, and as a fad diet.[1]

The British Dietetic Association list the possible adverse side effects as including "bad breath, a dry mouth, tiredness, dizziness, insomnia, nausea and constipation", and say that any person eating fewer than 600 kcal per day should be medically supervised.
