So the last few days I have been sleeping really well. Barely got up, was able to sleep in the morning which is something I have always done, I am a night person and I like it that way. However, while I was not cheating, between all the supplements I have been taking for some aches and pains and the extra nuts I have been snacking on I suspected I was not in ketosis. Yesterday I skipped lunch unintentionally and started what is now a 40 hour fast. Last night my sleep went back to how it is on keto/fasting. I woke up several times to use the facilities and this morning woke up an hour earlier than usual and could not go back to sleep (no matter how much I wanted to). I do not feel refreshed but I do feel alert. On the flip side I usually fall asleep earlier than usual with keto.
I have always had a bit of a delayed circadian issue but I like it and am used to it. When on keto it seems to fix it? Is that possible?
