Claim: Your Body Will Detox.
Our bodies are exposed to scant amounts of harmful chemicals every day — there’s no denying that.

All of the supposed benefits of detoxes are functions that actually performed naturally by our kidneys, livers and intestines — organs that could actually get more damage from a juice fast.

In an article on juicing for the New York Times, Dr. David Colbert told the author that the euphoria some juice fasters experience is a bodily process called ketosis. “That giddy feeling you get is what diabetics get when your body runs out of sugar and starts using other products for energy… I had a model come in recently, clutching the furniture, explaining to me that she’d been juicing for a week. Your sugar metabolism is completely out of whack.”
