I only have about 3 minutes here and have to go, please send for my free booklet all these questions should be answered.
With every breath of air, you build new cells and with every exhale, you remove dead cells, etc. All your tissues that were created not perfect will be destoyed as your red blood cells become stronger and better with fasting.
All the in-organic materials accumulated in your body will be removed, etc. This means plenty of bowel movements every day, regardless if you go 40 days with zero food, but your consuming fruit juice to supply potassium and natural sugars and these also aid the bowels.
"IF" you go one day with no bowel movement, you quit, you break the fast. If you ignore this golden rule of fasting, you risk clogging the valve in the small intestine that drains the acid from the brain, clog this valve and you go into a coma, open this valve to a coma patient and many open their eyes with in minutes.
Please read before you self experiment with fasting, my free booklet gives you my methods, you need to read many fasting books and then decide if this is for you.
