Is it healthy to drink only juice for a month?

The short answer is no. Juice does not contain adequate amounts of carbohydrate, proteins, fats, vitamins and minerals that your body needs on a daily basis to optimally perform its functions. There are sources/websites that promote juice fasting to alleviate every ill from cancer to arthritis and/or to rid the body of so-called “harmful toxins”. Unfortunately, there is not a shred of proof that shows juice fasting alleviates any disease or detoxifies your body. However, there is plenty of proof that a healthy diet and regular exercise is the best solution for health and longevity.

I do not recommend drinking only juice for a month. Juice fasting for a week or so is a good way to give your taste buds a rest from overeating, too much alcohol, or fried foods. Juicing provides nutrient dense beverages but is not recommended as a weight loss program. To lose weight and keep it off you have to learn how to eat. If you only drink juice to lose weight, you will regain the weight when you resume eating. Unless you change your diet to healthy wholesome eating once the juice fast is over, the benefits of the juice fast will be lost.
