    that’s a choice by an individual. doesn’t change how their body behaves due to millions of years of evolution.

    ironically, the thing that gave them the ability to make the choice to be vegan is the thing they are rebelling against. high volumes of protein, specifically those from consuming the brains and muscle of prey, allowed the species to grow larger and more complex brains.

    in a few million years vegans are going to be too stupid to make the choice for themselves and will return to consuming meat because they’re omnivorous.

      By your logic, obligate carnivores would have the larger brains. Humans are obligate omnivores. Studies show no significant differences in cognitive function, cardiovascular risk, or bone health when vegan diets meet recommended dietary allowance levels. Animal protein contributed during the evolution of the human brain, but the development was driven by cooking. Cooking externalized the energy required for digesting food, which allowed for a reduction of jaws/jaw muscles, and especially gut size, freeing energy that could be used by the brain instead.

      Also, the brain is fueled by glucose, not protein …
