No, I just accept the most credible evidence. 

But for me (n=1) since I cut out all modern foods and simply subsist off fatty ruminant meat I’ve: gained muscle, lost fat, hit PRs in every lift in the gym while not working out as often, I objectively heal faster, my “itis” have vanished, low-grade nerve pain also resolved, my silent reflux is gone, my dandruff has been reduced by 90%, my skin is flawless, I can go all day without eating and put in extreme effort while doing so, and my sleep has improved to a point where it is perfect - fall asleep every night in a few minutes and wake up 7.5 hours later no alarm like clockwork. 

Being a sugar / carb / vegetable clown (who still ate meat) in my previous life had lead to all those health problems. Eating optimally relieved all of them over the course of a couple years. Remarkable.
