I am on Day 5 of a fast (water, seltzer, tea, HWC and coffee) that I planned to end today at dinner. Starting on Day 3 in the afternoon I would get nasuea in the later afternoon. Took some electrolytes and it went away. Same thing on Day 4. I have 50 lbs to lose to be at a 25 BMI and that is the very least and that assumes I am big boned which I am not. So I have over 1500 calories of fat available.
No health conditions except hashimotos which I take synthroid, Keto for over a year. Fasted often for 5 days but not recently. This never happened to me except during my first month on keto. I did not get the flu, I got nausea whether I ate or not. It went away.
This morning was slightly nauseous again and was planning to take my blood sugar when I got up, I like to do this on the last day, no real reason. My BG which I take about once a month is normally between 80-90 on keto. This morning is 43! I have never seen that. I have no idea what my ketones are, the cheap breathalyzer that I use barely works on me. It was showing 0 after 3 days. Yesterday it showed .3 which is what it showed when I checked this afternoon.
I know the normal numbers do not apply to fasting if you are not on medication but this combined with the nasuea makes me wonder. It went away as I started my day. I took some psyllium in water which I take on the last day of the fast anyway, although usually a little later in the day. I managed to do what I had to do and not eat. Went shopping at a big box store (lesson learned never go food shopping on Day 5 of a fast, my bill was easily twice what it usually is). I feel ok, not amazing, A little foggy but not terrible. Is this a sign of hypoglycemia or simply a coincidence that my BG is low along with nausea
