How does the Master Cleanse (Lemonade Diet) work? Originally cooked up to flush purported toxins and waste from the body, Master Cleanse—also known as the Lemonade Diet—has only recently become popularized for quick weight loss.

That means 4 cups of salt water each morning, a cup of herbal laxative tea at night, and 6 to 12 glasses throughout the day of the “lemonade”—a concoction you make from fresh lemon or lime juice, maple syrup, cayenne pepper, and water, according to www.themastercleanse.com , one of the most comprehensive Master Cleanse websites.
