The Master Cleanse diet, also known as the Lemonade Diet, requires a strict liquids-only regimen over a consecutive 10-day period, as outlined in books like "The Master Cleanser" by Stanley Burroughs and Peter Glickman's "Lose Weight, Have More Energy, and Be Happier in 10 Days." Veering off the diet even for a day is not recommended, according to Glickman, because it results in disruptive food cravings.
U.S. News and World Report notes that the Master Cleanse claims dieters who give up solid foods and drink only salt water, herbal tea and a lemonade drink lose up to 20 pounds in just 10 days. However, according to WebMD, any drop in weight over that period is likely the result of a loss of water, muscle mass and bone. WebMD notes that dieters usually gain the pounds back quickly once they add solid food back into their diets.
The Master Cleanse diet also claims to detoxify the body, which can result in a number of symptoms, according to Glickman. He advises dieters to be aware of cravings, tiredness, boredom and caffeine headaches. Glickman also believes it is a mistake to alter any of the day-to-day steps in the strict regimen, because it could interfere with the necessary elimination of toxins from the body.
