Your Metabolism Will Slow Down.
You know how a tangerine can help your body absorb the iron in spinach? That kind of food-combo teamwork is a real thing and can be really affected by a juice cleanse. "Good fats are very important for the correct functioning of our body's internal processes. Removing these from the diet can mean the body can't perform at its optimum level," says nutrition expert Emma Brown."For example, fat-soluble vitamins A, D, K and E require fats in the diet in order to be absorbed. If your diet does not include some fat, the uptake of these vitamins from food will be limited."
On the flip side, you may also get a dose of nutrients that you weren't getting—especially if you were reaching for a lot of carbs during your regular day-to-day. Juices are an easy way to drink vitamins and nutrients since they are readily available in liquid form; however, they should be used as a supplement and not as a substitute for a balanced diet.
First thing's first: Juice cleansing is a "detox" diet that can last from a few days to several weeks in which a person consumes only fruit and vegetable juices to obtain nutrition while otherwise abstaining from eating food. Many people swear by cleanses and report an improvement to their health, mood, and appearance. The scientific community, however, is less than enthusiastic about juice cleanses—many scientists, dietitians, and doctors regard detox diets as less effective than fasting with water, and, therefore, a waste of money. That said, if you're going to do one anyway, we recommend consulting with your doctor—or at the very least going along with an "official" juice cleanse program. Simply drinking any ol' juice from anywhere around town is not a good idea.
