If you are herbivous or omnivorous then you use different foods to make up your nutrients, but the body simply needs enough calories with a complete nutient profile according to your lifestyle. The rest is nonsense.

I'd agree with all this......if you live in a modern country with access to everything you need food and or supplement wise....and you are lucky enough to have a metabolism that can handle it...most people don't.....a vegan diet can absolutely work.
In most places around the world though....you'd simply become slowly malnourished on a vegan diet and get sick.
I'm reminded of a something I saw published by Michael Houston PHD, Professor Emeritus of the University of Texas Health Science center concerning veganism where he wrote "
Perhaps 10 to 15 percent of the world wide human population have a metabolism that can be successful being completely free of animal products in there diet"
