A juice cleanse is a dietary regimen that involves consuming only fruit and vegetable juices for a set period, typically ranging from a few days to a week. The goal is to detoxify the body, promote weight loss, and improve overall health. Proponents believe that the nutrients in fresh juices can help eliminate toxins and provide a break from solid foods. During a juice cleanse, individuals often drink several bottles of juice each day, which may include ingredients like carrots, beets, and leafy greens. While some people report feeling more energized, health experts caution that juice cleanses may lack essential nutrients and can lead to fatigue or other health issues if done for extended periods.
