I do fine without meat. I haven't eaten meat, or lard, meat broth etc since 1985, almost 40 years. I do eat dairy & pretty much anything healthy, loads of fresh vegetables & fruits, nuts, legumes, whole grains etc. Never been overweight, blood tests always good. Eating a variety of healthy foods is the best thing you can do for yourself (& exercise of course), just go to places like Italy and see how they eat. Food fads like the current carnivore stuff aren't going to work out long term for good health & will die out like all other diets/fads. 

 You have no idea what you’re talking about.
