This detox has been a “diet” for decades. It was commonly used for women who wanted to lose a few pounds in a hurry and can be dangerous if abused. Try to only do this for two to three days. The cranberry detox is very simple, only drink pure cranberry juice and eat nothing all day. It is recommended that you only consume four to six, eight ounce glasses or two to three sixteen ounce glasses. If you want to add this to your diet as a daily detox, drink up to two sixteen ounces of cranberry juice every day along with your regular diet. The one trick to this detox is to stay far away from cranberry cocktail which can have the opposite effect due to all of the added sugar in it to make it sweet.
