It's NOT healthy, and it sure ain't happy.
So! You're thinking about trying one of those “juice cleanses” everyone's been chatting about.
A juice cleanse or juice fast, if by some miracle you haven't been exposed to the concept, is a diet wherein you consume JUICE AND ONLY JUICE for a period of time, usually a few days. Lots of companies offer pre-packaged sets of juices to make it simple for you.
This supposedly helps “detox” your body, encourages weight loss, and packs you so full of fruity nutrients and veggie vitamins that you become a magical being made of light and float away to a place in the sky where you shall never want for anything again.
The companies that sell cleanses are great at making you think you'll feel like this:
You'll just float along for days on a cloud of virtue and weightlessness!
You'll have all of the energy, all of the time!
