People think that they have to eat meat to gain muscle and that we are born as carnivores. They say that your health is at risk if you are not eating meat. They also say that humans wouldn't have become human if we didn't eat meat according to a TIME magazine article, "As a new study in Nature makes clear, not only did processing and eating meat come naturally to humans, it’s entirely possible that without an early diet that included generous amounts of animal protein, we wouldn’t even have become human—at least not the modern, verbal, intelligent humans we are." I find this to be utter ignorance! This is speculation at it's best because researchers like Lloyd Pye, Erich von Däniken, David Willcock, , Zecharia Sitchin, and many others would argue that we didn't become human until we met the anunnaki. The anunnaki spliced our DNA with there own which accelerated our evolution thus we became intelligent human. This may be far fetched but a research who created the documentary, "Everything you know is wrong," further supports this theory.
Let me tie this into perspective we have been eating vegetables since the beginning of our existence and meat was an option we chose to help us survive through the winters. We also need their fur to keep us warm mainly. If we are such carnivore then why do we need to cook the meet? Wouldn't we be designed to eat it raw? Meat did not make us human it was simply another source of protein. When you look at the structure of our teeth we only have two canine teeth and the rest are slightly jagged or flat. Also many people don't point out that our canines are extremely small compared to any other canines found on any other animal. Thus we could and can survive just fine without meat as many many people do. Many indigenous tribes eat only vegetables for more info go to https://en.wikipedia.org/wiki/History_of_vegetarianism.
Why Should You STOP eating meat?
I ate meat for 35 years, however a friend of mind (Christopher Tims) brought it to my attention that beef, pig, chickens, and fish consumption is a detriment to our earth. An interesting statistic is that for 1 lb of beef consumed, 5,000 gallons of water is consumed. Not to mention the 100 lbs of food used to feed the cattle. Furthermore many many animals experience fear prior to its death, this energy is then transferred within the meat into our body. Note: Physics 101 points out that energy cannot be destroyed nor created.
Will your immune system be affected if you don't eat meat?
Not if you take the proper supplements. I would consider speaking with a professional about what to take for supplements. I don't take a lot of supplements and my doctor said I am in perfect health. You can get protein from plants and take B12 supplements also meat has creatinine which you can also get as a supplement. Once again consult a professional nutritionist.
Is it hard to change?
Yes. I highly advise to take it slow. For example: start cutting out meat 1 day out of a week, the next week try not eating meat for 2 days. The following week try to go 3 days without meat and so on.
It depends on your body!
Some people have to eat meat some don't. What works for one person may not work for another. I am fortunate to have a healthy body and what I am doing now is working. Also I listen to my inner self. For example: Many times I will ask the question to myself how can I best serve myself and those around me. The universe will then bring into my awareness of a supplement I should take or a type of exercise I should be doing and so on. In the end you are the answer to your current situation though it is important to seek answers from professionals also.
I hope this helps!
