Many misconceptions have been looking on Vegetarianism because a lot of people have tried to change from a diet of meat eating vegetarian with limited knowledge. They feel tired and sick, and blamed changes in diet and eat normally again in the flesh. There is good reason why this can happen.
When a person eats the meat and the toxic food for a long time, the body usually stores these toxins in the body somewhere in fat tissue, tumors, and the bowel wall and mucosa hardened. When the person changes their diet, the body often begins to wipe of the toxins released in the flow of blood and making the person feel sick and tired. Blame the person's diet, thinking it is no nutrition and then switches back to the meat. When this happens, the body to be cleaned, because all your energy to digest meat and enters the person feel better again.
This is a serious error in the stage of "transition" the person can feel it sometimes a bit lousy, but it would have felt much better in the long term. In general though I certainly feel better in two points clear when that was not there. Also in the diet of meat toxins are accumulating for ever and is often expressed as a disease further down the road.
Personally I felt better when I changed to eating vegetarian, I like to gradually replace the beef tofu, TVP's and other high-protein "meat substitute". Although these foods are not optimal for nutrition due to its low digestibility coefficients (even better than the meat), I still felt very good. The process of cleansing for me came later when I made a proper cleansing program, which contornearé later. I consider this the most ideal way of changing the meat. Still consuming salt, cooking oil, sugar and other food "toxic" (see letter acidic / alkaline foods) as before, but just to the left out the meat. The process of cleansing and the transition was delayed and occurred in stages that were manageable.
