Very similar to the detox teas, juice cleanses are also a popular weight loss fad. In the case of a juice cleanse, the dieter only consumes fruit and vegetable juices and skips solid foods. Like the detox teas, there’s very little research to show that this sort of approach is effective, says Brian Kiselstein, editor of Think Healthy Fitness and a certified fitness professional.
“Juice cleanses are something that you hear about every so often, but rarely hear included in a success story,” he says. “That’s because there’s very little research to show that these cleanses are effective and worth the effort. If you don’t eat for seven days while on a juice cleanse, you probably will lose weight (how could you not?). But juice cleanses are not sustainable and, when you start eating again, you’ll probably gain the weight back right away.”
At best, a juice cleanse will lead to a very up-and-down weight-loss journey that can be hard on the body, not to mention the negative mental effects, adds Kiselstein. “Juice cleanses do not promote a healthy lifestyle and won’t make you healthier, other than just losing a few pounds.”
