The Master Cleanse, also known as the Lemonade Diet, was created by Stanley Burroughs as a diet plan to aid in quick weight loss. Proponents believe cleanses, or detox diets, rid the body of accumulated toxins and waste products that lead to weight gain, lethargy, digestive upsets and generally poor health. MayoClinic.com notes detox diets are not scientifically valid and could lead to further health problems. Although the diet plan will aid in weight-loss, it is typically water weight lost initially from calorie and nutrient restrictions. Consult with a physician before starting a cleanse to determine healthy meal plans.
