What Juice Cleanses Actually Do

Juice cleanses promise a reset — flush the toxins, rest the gut, start fresh — and plenty of thoughtful people have tried one, usually feeling genuinely lighter by day three. The trouble is what the evidence says about why: no study has shown that juice removes toxins the liver and kidneys weren't already handling, and the lightness is mostly water loss and a few days of eating less. That doesn't make anyone foolish for trying one; the marketing is polished and the appeal of a clean slate is real. It just means the benefits on offer are available without the costs.
