Fasting is a traditional method of eliminating toxins and gaining spiritual clarity.
But it must be approached with caution.
How you begin a fast, how you break a fast and what you do during (or
don't do) during a fast are all considerations.
Fasting affects your body in quite significant ways.
If you are interested in fasting, then do some research beforehand; find
out if it is the right approach for you.
During your fast, drink filtered water, avoid driving and try to rest.
