The week of slow is the running equivalent of a juice fast. Some people use short-term juice fasts to hit the reset button on their diet. The fast is not an end in itself. The goal is to make permanent changes to their diet, replacing bad habits with good ones. But instead of just making these changes from one day to the next, they first take a few days to break their attachments to the old habits by consuming nothing but healthy fruit and vegetable juices. Then, once they are no longer craving potato chips or whatever else, they return to a normal but improved diet.
