Good question. Also, how will you know when you are finished?
Another question, I just completed a 60-day water only fast. I did occasionally have raw lemon juice with some olive oil added to it, but it was about a gallon of water a day and nothing else for 60 days. I had to stop when the in-laws moved in for the winter and will start again in the Spring.
Would a long fast such as what I did get rid of the liver fats and stones by eating them up because I am aware my body was very busy burning up the toxic wastes and passing whatever it could not extract nutrients from on its way out.
There was also some deep healing response and I am no longer diagnosed as "pre-diabetic".
Got rid of all the cellulite doing that and felt GREAT!! the whole time. Eating is really a drag now.
I never had any stones come out because with the long fast method the body would have re-absorbed them and extracted any possible nutrients locked up in them. That's the theory anyway.
Here is the instruction I followed while on the Long Fast:
