Curious if anyone else struggles with these issues-
I have gone on and off keto. I was able to transition into carnivore and stay on it strictly for about a year. My issue is although I make ketones I could never go longer than about five hours without eating. I tested ketones and blood sugar religiously multiple times a day (for curiosity mainly) and after about five hours my blood sugar would start to rise and I'd get jittery. If I pushed past it anyway in an attempt to fast, I could not sleep at night at all. Super wired, like being on bad speed. If I go into lower calorie, same effect. I never adapted, even after a year. In fact, I had to start adding a few carbs back in because I was starting to grind my teeth so bad. To this day I still cannot fast nor go too long without eating. Even with zero carbs my blood sugar will start to climb into the 100s, I'm assuming due to stress hormones. I have come across other people who do not sleep well on keto, although most report improved sleep. I think perimenopause was playing a role in all this, I have lost stress resiliency in general. Things like fasting, getting too high in ketones, cold plunging, etc all cause similar symptoms. Although I feel better overall when I can find a sweet spot with carbs and do not go too long without eating, i never seem to get "fat adapted." Just curious if anyone else struggles with this.
