I'm a pretty healthy guy and I was trying to go on a juicer diet for at least 5 to 10 days. Would any doctor recommend that if im healthy?

Any doctor??? Probably not. Why do you want to do this? Claims of getting "detoxified" are just claims. There's no medical justification for it; potential side effects. Spiritual quest? That's a different, and metaphysical issue beyond the scope of this forum. Besides, like taste, there is no arguing metaphysics.
No. And if you want to stay a healthy guy, you won't go on a juice diet. It's a lousy and unhealthy way to eat, and you detoxify nothing.
No. A well balanced healthy diet with an appropriate amount of exercise will always be recommended over any type of "fad diet" including a juicer diet!
