The medical orange juice fast only wants the potassium from the orange. The pulp is strained and throwed away. 1 pint of strained orange juice does not produce 3 bowel movements! it is all the waste that is accumulated in the body that comes out!
Skinny or fat, makes no differance. I have seen the amish hard "FAST" a 85 pound woman with a dead thyroid and some days this skinny near dead woman got no water even! at the end of 14 days she had a full thyroid function blood test proven ans sent home healed. Her blood healed her, not the Amishman, he only supplied the method. "FASTING" during sever disease is an art and not something for the general person to experiment with.
The above fasting method for this near dead woman was advised to this Amishman by one of the most modern and well known medical clinics in America and if the name of this MD was ever found out, he would be flipping hamburgers for a living! Several MDs have lost their licenses for helping the Amish with Natural ways! The medical world is a very cruel world driven by $$$$.
