A juice fast means getting a set of usually six juices from your local purveyor of juice that you will drink over the course of the day without consuming anything else other than water. The juices in a fast are specifically meant to carry the nutrients your body needs throughout the day.
Why do this? Because it resets you and can make you feel more energized. Sometimes we benefit from something a little more drastic to remind us to take care of our bodies. Then caring for the rest of your life will hopefully follow!
This is not for everybody and I do recommend talking to your doctor before trying it to make sure it’s healthy for your body.
