Some would say keto is a way of eating as opposed to a diet that can been seen as a temporary change of eating habits.
I've never heard anybody say that keto causes brain fog. In fact a lot of people describes the opposite result which I would think most search results are about. There's also something called "keto flu" which some people experience for some time when they switch to a keto diet.
These terms are pretty vague and the best way to get a better understanding is too try keto yourself. It's just a different way if eating. You don't have to cook fancy meals and you can stop at any time.
I did keto for 5 months or so back in 2014. I found the brain fog description very apt. I couldn't think beyond a couple of moves ahead, which began affecting my work. Going back to a normal diet I was fine again.
Because saying "it depends on the person" is akin to saying "there are too many (possibly unknown) variables at play to actually figure out what causes what".
Nutritional sciences have it hard. it's basically impossible to really isolate cause and effect while staying moral with complex organisms like humans
Especially because it might not be up to the human, since our digestion relies on symbiotic gut bacteria, which we don’t have good ways to test what they even are.
