The Master Cleanse
This is one of Hollywood's hottest diets. Celebrities such as Beyoncé, Ashton Kutcher and Demi Moore have waxed about the quick weight-loss benefits of the Master Cleanse. The only problem? This concoction of lemon juice, maple syrup and cayenne pepper was never intended as a weight loss plan. Instead, it was created as a body detox system to bring the body's pH balance from an acidic state to an alkaline, or healthy state [source: Master Cleanse].
Cleansing can help people reset their eating routine if they've gotten into bad habits. And while it may make them feel good, cleansing shouldn't be used as a diet plan. It can't be maintained and the weight will return along with regular food consumption.
