Do juice fasts work?

Question: "Can a juice fast help me lose weight?"

Expert Answer

"Not for long. Skimping on calories -- you take in as few as 900 calories a day on one popular fast -- can slow your metabolism; so can an inadequate consumption of protein, because it causes muscle loss. Plus, you'll gain weight immediately when you start eating normally, says Ellie Krieger, R.D., host of the Cooking Channel's Healthy Appetite."

"To help lose weight, probably. For long term weight loss, probably not. Unless you plan to be incapacitated, and don't plan to engage in any type of physical manual labor. It's probably not a good idea to do this for more than a few days." Submitted by copayextra
