Yeah, that is correct - I am already out of ketosis. And I feel really better, all my struggles ended. Will do measurements tomorrow as well just out of curiosity, because not planning to eat soon I think after all those carbs I had today (around 70g net carbs).
So if anybody is interested, how it is for a brain, in my case - as I have mentioned I am in tech industry and thank god that was a moderately easy month for me - for a whole month I could not finish my major task. I just could not find a solution. After having those carbs today, after a while my glucose spiked to 110 and I found a solution in 5 minutes. Brain on ketones vs brain on glucose. Despite my inability to utilize ketones, I had 3 episodes during my keto period, where it clicked for 10h each time.
It is different. Of course I am only speaking for myself, but when I was in this state of, let’s call it proper ketosis, it is different for a brain - it is sort of a seriously survival mode. You are focused, have lots of strength, but it is aimed towards action, towards hunting, towards fighting, yes and you feel like your body gets stronger as an organism - and this is probably how any sort of healing effects are achieved through ketosis. But when a strategic / abstract planning is required - I was not able to utilize this state for this. So for instance to come up with an algorithm / solution for an abstract problem. And this is when glucose as a fuel works best. Of course, I didn’t have much time to test “proper ketosis” state, but did as much as I could.
In my personal somehow limited opinion, I can say that glucose is superior fuel for a brain in our current age, where everything is digitalized / abstracted. Ketones were probably best option where we had to fight for a food instead of making orders through the apps of our smartphones. Of course, if some one is able to utilize ketosis for healing effects - that is great as well. Considering the power I felt - it can beat everything. Yeah, and for a military purposes it is way better then glucose, however I would say that a combination of glucose and ketones oriented soldiers would work magic in a field. I have to admit I am missing it already
