Second 72 hour fast was so easy!! It really gets easier every time. I didn’t use to be able to go without food for 3 hours, let alone 72!!! Without issue.
In hindsight I should of kept a check on my sugars a little more but I’m glad I stopped when I did.
Really enjoying my fasting, and then planning my fast breaks my meal for 3 days, today… a fathead pizza!! 
High ketones and a bit of hypoglycaemia

The lower blood sugar shouldn’t be a problem in the presence of higher ketones, your body is using them for fuel. Assuming you felt well when you took those readings? I’ve seen 2.9 before when fasting and felt absolutely fine (ketones were 5+).

Thanks Duncan. I’m actually doing this way of eating for reactive hypoglycaemia (got crazy insulin with no resistance) and weirdly used to get symptoms at 4.2 (had very low lows too) however, your right I had no symptoms!!! I was actually shocked when I saw that number.
You’ve just given me a clarity moment, just realised now my body is fat burning, I don’t need the sugar in my blood.

Hiya,
Yeah that was my ketones after a 72 hour fast. Only just started doing them after 6 months of keto. I’m still waiting to see if it’s helped my fasting insulin, should get my results this week.
I’m prob not the best person to compare bg with. Mine are often on the low side with my RH. They are so much better now through keto though
