I felt to add something important about this fast - it is very powerful indeed, and is very challenging to the system. It's best undertaken when you've already done a at least a few years work cleansing your system by improving diet, because it will release toxin quickly, and then the body has to work hard to cleanse it away. This can feel pretty unpleasant and destabilising whilst it's happening.

So yes, it's something well worth doing to facilitate evolution. Yet you would need to be well prepared for it because of the powerful shifts that take place.
