Myth 1: You need to detox your body with a juice cleanse.
Fact: From celebrities to personal trainers, there's no shortage of so-called experts advocating fasts or juice cleanses to detox. If you Google "detox," you'll get nearly 64 million results for diet programs and treatments that are supposed to help "flush out your system," "remove toxic substances from the body," "give your GI tract a rest," or "speed up your metabolism" and "enhance your overall health." But despite all the hype and popularity, there's little proof that fasting or following a deprivation diet for several days actually delivers on any of the above promises.
While an occasional short fast or a day of following a "juice diet" won't cause harm for most healthy people, it will likely leave you feeling cranky and hungry. If you really want to be and feel your best, eat a healthy diet that includes plenty of fruits and vegetables, get adequate sleep, and don't drink more than one alcoholic beverage per day.
