Juice fasting, also known as juice cleansing, is a fad diet in which a person consumes only fruit and vegetable juices while otherwise abstaining from food consumption. It is used for a detoxification alternative medicine treatment and is often part of detox diets.

This fad is promoted with implausible and unevidenced claims for its health benefits. [1]


Juice fasting is closely associated with detox.

Catherine Collins, Chief Dietician of St George's Hospital Medical School in London, England, states that "The concept of ‘detox’ is a marketing myth rather than a physiological entity. The idea that an avalanche of vitamins, minerals, and laxatives taken over a 2 to 7 day period can have a long-lasting benefit for the body is also a marketing myth."[2] Detox diets, depending on the type and duration, are viewed as potentially dangerous and can cause various health problems including muscle loss and an unhealthy re-gaining of fat after the detox ends.[3]

Juice mixes containing grapefruit juice may also adversely interact with certain prescription drugs.[4]
