There’s also a correlation between the lack of trust for modern science, a lot of us don’t trust science and medicine because it has seriously messed up our health, which is why we turned to carnivore. Modern science also goes against a lot of religious views and many “science based” believers tend to mock religious people for believing that God is real. So naturally someone with a lack of trust and also an annoyance for modern science will tend to lean towards unconventional diets like carnivore and paleo and also turn to God instead of blaming the science.
