You will lose significant weight in a short period of time if you successfully complete a juice fast, but that is the only advantage. Your overall health will suffer, and the weight will return as soon as you go back to whatever you were eating before.
Juice is much easier to digest which allows it to pass through your system quickly. The biggest advantage to juicing is that it gives your body a chance to rid itself of all toxins that we've built up over the years. You will be drinking a lot of liquid which helps the kidneys flush out everything while losing weight.
A juice fast is typically an effective way to lose excess weight in a short period of time. Over time, they have proved to be popular among those wanting to drop a few extra pounds due to many fitness and nutrition 'experts' as well as celebrity endorsements. By limiting caloric intake, the body sheds pounds. Meal planning is easier too.
Although a juice fast is difficult to follow, the benefits are impressive: weight loss, release of toxins, blood sugar regulation, increased mental clarity, strengthened immune system, and heightened energy levels.
