Joh The reason so many people have problems with their diet is how different the world we live in is from the world we evolved in. Just like we have much more access to sugar and salt than our ancestors ever did and it hurts us, we also have more access to plant-based protein sources. Not having to rely on meat can be seen as an achievement of our development. What got us here won't get us there.
That said, I am remaining an unapologetic carnivore myself. Sometimes the appropriate side dish to a steak is bacon.
