If you are human you don't have to look further than the make up of your teeth. Most humans have canine teeth that are no longer sharp, in comparison to our ancestors who had very sharp teeth to bite into animal meat. Our back teeth are flat and hard because we are meant to eat nuts and seeds and vegetables. My theory on eating any food in general is what is the energy source. It is energy in and energy out ultimately. I have made the switch to eating vegan because if you look at lions, lions kill fresh meat and eat fresh kill. Which means the essence and life of that animal has a energy transfer of life energy, whereas some lions are scavengers and eat the scrapes of the left over meat. Most humans on the planet are scavengers because unless your eating organic meat your eating low energy tortured animals and transferring that negative conscious energy to your body. So it not only effects you physically but also mentally and spiritually. These concepts are not very hard to understand something all of us know deep down but we still choose to eat meat, I myself am guilty of this. In truth there is nothing in meat except taste and texture. So the question to ask here to yourself is...is eating meat based diet worth it for the nutrients and amino acids when you can get the same benefits except maybe b12 at the cost of giving you poor energy and low life energy transfer? If you really enjoy the taste and texture of animal meat there are tons of vegetarian alternatives that can help wean off of meat.
If you are in fact human you don't have to ask anyone but yourself. Just be honest with yourself yes I eat meat and these are the consequences I am faced with eating this way. I am trying to stop eating meat but it has been a challenge because I have eaten meat my entire life.
