Will fasting metabolize “waste material” before healthy tissue?
I personally have enjoyed the benefits of fasting in various different ways and have never experienced any harmful side affects (other than those which stem directly from the elimination of toxins themselves such as irratability, dry mouth etc). It makes sense to me that the body would first look to clean out excess buildup and old waste, and that cannibalizing itself is a last resort. If you are concerned about this still, try a juice fast, in which you will still see many benefits but is much easier to maintain and easier to stay healthy on.
The explanation has mixed two different processes. Fasting doesn’t work because enzymes are being redirected from the stomach. It works because when you reduce the toxic load on your eliminative organs (wherby the main source of toxins is that junk you’re eating and drinking) they are freed up to process other toxins already stored in your system. The mechanism for toxin elimination is distinct from energy metabolism. When we say that a body “cannibalizes” itself, this tends to refer to the process whereby, when deprived of energy, the body will not only metabolize fat but also protein in the muscles.
