I've just tried for the second time 72-hour fasting. This time it ended up 74-hour. My average BG (7 days) before fasting was 87 mg/dL. During the 74-hour fasting, on the second day, I've got FBG 70mg/dL, but I guess before the dawn phenomenon period (I had insomnia and woke up really early, like 3 am). During the day, it was getting higher and higher until 79 mg/dL (10 pm). The last day, it kept getting higher, and it ended at 85 mg/dL, awesome for my standards. I also measured ketones during fasting: day one 2.7 mmol/L, day two 5.7 mmol/L and day three 7.1 mmol/L.
This time I was able to break it without problems, I've started with very low quantities and ate more and more on the next meals.
What seems to be surprising is that the day after fasting my FBG was higher than usual (95 mg/dL), and the next day even higher (98mg/dL). A while ago, 10pm, 7 hours after last meal (I do OMAD), it was 103mg/dL, 1.6 mmol/L ketones. Around 10 pm, 11 pm, I usually get my lowest BG, usually down to 85 mg/dL sometimes (I do suspect that below 2 am is even lower, but I am sleep), but today is really higher.
I understand that such kind of thing might happen during fasting, but is there a theoretical explanation for it to happen during the days after it?
I am on low carb diets for about 6 months now. And since a month ago I'm on carnivore, and I just love it. I didn't change my meal quantities either before and after the 74-hour fasting (I kept 2100 calories, <10g carbs, <105g protein and the rest is just fat, sometimes up to 200g).
