The body is perfectly designed. Just think how you can cut your finger and in a few days the wound is sealed and almost healed! your body can digest the bad and replace with the new.
Properly done a proper fast can renew the body. Depending on your elimination channels and your ability to follow instructions of Nature, you may acheive your wanted results in one session or come back and try again after the body is recoverd.
As long as your body is actively expelling acid waste, the fast is repairing old tissues, when the acid waste slows downs or stops, you stop the fast. In a few months you then try agaon if you desire, all the time living on live foods to supply the liver all of its daily needs.
Scars do dissapear! For now you can eat 1 pineapple per week, when you cut out the flesh, take the outside halves and take a nice hot shower, then rub these pineapple halves all over your body!!!!!!! These live enzymes will eat your old dead skin cells. Let sit as long as you determin and then shower off. On your scar areas, apply direct pineapple juice!
Be careful around the eyes, etc., pineapple is quite powerful!
