A Juice Fast Is Not A Detox

  The point of a juice fast is not to nourish your body, it’s to rest your digestive system. There’s nothing wrong with it, as long as you’re juicing mostly green vegetables (not fruits-too much sugar!) But you’ll probably feel very hungry consuming nothing but liquid, and that can make you really crabby. Also keep in mind that any weight you lose while juice-fasting will likely reappear as soon as you start eating again.
