The detox diet group didn't seem to be enjoying their food—was the sacrifice worth it? "It had no impact at all," Dr. Oz says. "I was surprised by this, because I really thought we'd see more of an effect."

Dr. Oz says the women involved in the experiment were generally healthy, even though they drank a bit more than they should and might not have been taking ideal care of themselves. "But what we did find was that the liver was doing the same things. You had the same kinds of toxicities," he says. "Because toxins that we get into our body go to our fatty tissues. They go to places like the liver and the brain. It takes more than 10 days to get them out."

Even though detox diets can't cleanse the body of toxins in such a short amount of time, Dr. Oz says these diets can be useful as a jump-start to healthier eating. "Now that you've moved to a whole new place in what you tolerate and expect in life, it's easier to go from there," he says.
