Juicing to lose weight or "cleanse" is not only unsuccessful, it can be downright dangerous. If you're drinking juices in place of real food, you'll fall short on a number of nutrients your body needs, namely fiber and protein. Fiber keeps us full for longer, preventing overeating. Protein also keeps us full and helps us build and maintain lean muscle mass, which burns calories even at rest.

If you cut your calories too low because you're just drinking juice all day, your metabolism may slow down. Then, once you start eating solid foods again, you'll likely put on weight in the form of fat cells.

Your body has two wonderful organs to do any cleansing you need--your liver and your kidneys.

Freshly-prepared juice can certainly be incorporated into a healthy diet.
