your brain is fully aware that you can just have two handful of nuts and be good for a couple of hours. Just because your brain also believes that you gotta have a proper meal doesn’t matter
I’ll see your handfuls of nuts, and raise you a couple spoonfuls of peanut butter.
It’s a) relatively cheap b) delicious c) easily edible on the fly with a spoon, time constraints be damned. It serves the purpose quite well, and even throws a bit of sugar in there too.
Not exactly a balanced diet, but it does accomplish the goal reasonably effectively and frequently is already in the house.
Also good when not medically quite at 100% - when not at my best, I do everything I can to follow dr. orders, ofc, but sometimes it’s more efficient to throw a tiny bit of sugar at one’s brain in a (relatively) healthier way, than to keep fighting it during recovery.
I don’t have any nuts in the pantry because I don’t like them. My brain knows this.
I saw someone make “mashed potatoes” out of Pringles… seriously wondered why. But they did.
