Humans are facultative carnivores. You get the vast majority of your nutrition from animal products. Even modern manmade plants in the store are nowhere near as nutritious as people think they are. Humans have been eating mainly meat for over a million years. Wild plants are fibrous and will starve you in a survival scenario, there is not a single example of a vegan pre-industrial tribe or human society.

Eating a clean human diet with lots of fatty meat reduces inflammation. It regulates hormones. It puts your body into a fat burning and muscle building mode very easily.
