Wanna start juicing. should i take one type of juice daily or can take different juices. if so then what juice should i take and when?

Any: There is not an exact science to juicing. Try once daily or combinations of juices. Use what works best for you!

Vegetable-based: Juicing has been a weight loss and health benefits fad for a number of years. The mechanism of weight loss is due to the marked reduction in calories, assuming you will be juicing for all meals. I wouldn't recommend this in spite of the hype. It is neither sustainable nor nourishing. You would be better to use juicing as a supplement to a calorie restricted diet and 3-5 times a week exercise.
