Once we quit beef, the enzyme that is needed for digestion disappears within 2 to 3 weeks. Once the enzyme isn't there, if you do eat beef, it will simply lie in your stomach rotting while the body begins to produce the enzyme. It takes about 24 hours and a person will run a low grade fever, have an upset stomach and become extremely fatigued. It is like having a 24 hour flu and I have come to believe that this is the only 24 hour flu that exists. A person needs to eat a beef meal about once a week to keep the enzyme at the levels we need for normal digestion. It is an ugly reason to eat beef. It is a good reason why one should never eat it again.
