I think my body probably functions better consuming lean protein, but I am a vegetarian. Have been off and on for decades but my most recent stretch has been 7 years. I guess I must backpedal, becuase I eat fish maybe twice a year, so can’t really claim to be totally veg. But even when I was a meat eater beyond my childhood late teen years, I rarely prepared it in my home and ate it infrequently at that. I do believe once can have a more symbiotic relationship with animals of meat is abstained from.
