Basically there are 4 types of people.

I'll use the pool.  The first three, there are those who want to look at it, those who want to stick a toe in, and then those who will jump in!  I haven't mentioned the 4th type. Those who will ignore its existence. 

The same is true for juice fasting and getting healthy in general. So many people want to tell you why it's dangerous.  Have they done it themselves. Well no. But I know of some one who did and it made them sick or they just gained all the weight back.
