As a weight-loss solution, a juice fast just doesn't really do the job. Whatever weight you lose, you'll put back on once you start eating solids again. Although I'm a big fan of fruits and vegetables, as a diet plan, fasting takes a good thing and goes too far.

"I have tried juice fasting many times. It is the best for weight loss, body rejuvenation and strength, and mind clarity." -- An iVillager

"You will be doing your body a disservice by trying to lose weight through this way of starving yourself. If you consume too few calories to support your energy needs, your body will sense it is starving and slow down its metabolic rate, which works against your goal of losing weight." -- iVillager mdhellweg
