how does fasting work?

When you fall asleep, your body switches from an EXTERNAL FUEL (eating) to INTERNAL FUEL (fasting). Specifically, internal fuel is when your body is using carbohydrate reserves and fat depots for fuel. I know it sounds crazy, but your body does that automatically every night. During deep sleep, the body takes everything it needs from within and uses internal energy to cleanse and detoxify the system! By the way, Halitosis (bad breath) and a coated tongue in the morning are signs of detox. For that reason, a coated tongue is a sign of toxicity and therefore a perfect candidate for a fast. 

To explain, the word "break-fast" comes from Old English and means - BREAKING THE FAST! You break your nightly fast with the first bite of muffin or bagel (which seems to be the staple in western countries). 

Therefore, fasting is a natural part of your life.
