The benefit of ketosis, cellular cannibalism, which usually occurs within 12 hours of fasting is that it reduces the overpopulation of sluggish cells, leaving the stronger cells and those that overproduce prostaglandins. This is a process of mass genocide via cannibalism. The deleterious effects are that blood maintains a higher acid ratio weakening and damaging red blood cells and their ability to transport oxygen. If fasting continues beyond 2 days severe blood-fat deficiency occurs. The body leeches fats from the lymph system and cells to maintain it. This fatleeching weakens the immune system. Another deleterious effect of fasting is that the necessary bacteria level in the intestines diminishes. Since 60-90% of fecal matter is born of bacteria, constipation results and severely diminishes bacterial synthesis of B vitamins and amino acids. This further weakens and diminishes the immune system. Another side effect from fasts, resulting from blood-fat end lymph deficiencies is that many toxins from either industrial pollution or natural by-products of metabolism are freed. They irritate, burn and often imbed in the stronger cells, therefore weakening them. Fat, especially in lymph, usually binds with toxins and either neutralizes or escorts them out of the body through the mucus membranes, skin or bowels. If great collections of these toxins occur during fasting, kidney damage results. These side-effects usually create edema, especially when eating is resumed. The body often tries to dilute the toxins when it does not have enough fat to chelate and remove them. Mutations some-times result.
