Yeah it must be regional… I am a Hungarian and I never saw a hot cross bun here and it has nothing to do with Christian customs either (Christianity is big here and I know a lot of things about it. Originally I “belonged” to the Reformed Church as my anchestors but I don’t follow a religion. I just was baptized). We have the usual fast here. Not hot cross buns but not the super strict special rules either.
Carnivores still consume carbs, it’s individual but I usually get 3-20g carbs from animal products, sometimes more.
I don’t know about that, never heard it. I suppose the human body is way smarter than that but maybe Paul actually know what happens when one eats a few or less carbs a day AND drinks some booze. I am interested What if it’s a lot of booze? Of course a sugar free kind.
But our brain needs some glucose, no way the body neglect it. It somehow handles everything, that’s sure.
