How long can you fast before YOUR blood sugar rises ?

Answered on August 19, 2014

I'm in the midsts of a 4 month n=1 experiment. I've monitored blood glucose and triglycerides while fasting several times now. Here are a couple consistent yet counter-intuitive observations;

1) 8-10 hours into a fast, blood sugar begins to rise (I assume Gluconeogenesis)

2) 14-16 hours into a fast, triglycerides begin to rise (I assume Lipogenesis

I am in nutritional ketosis (serum verified) and probably mostly keto adapted. I'm wondering how this may change as I further adapt to burning fat.

How long can YOU fast before you see blood sugar rise ? How high does it go ?

I should add my wife takes longer than I do (no IR) and we both can push glucose up right away with HIIT on a fast.

I don't think it is relevant, if anything I'm much more prone to liver dumping and hyperglycaemia.

don't forget to mention that you are T2 diabetic borofergie. it may be relevant

AM ketone's are always around 2 m/mol. May this be Insulin resistance + keto adaption at work ? My LP IR is was 45.

after 3 days of water fast my glucose readings went straight down to 70-85 and stayed there until the end of the 6 day fast. I don't understand the "up" in this question

I find that when I'm in ketosis I can pretty much keep going without being aware of any blood sugar fluctuations. I notice that I might feel hungry but in reality I'm not actually that interested in eating other than for the joy of tasting food.

Having said that, if I've "fallen" out of ketosis and I'm being pretty active and so using a temporary increase in blood glucose through an increase in carbohydrate intake, then I'll be much more aware of what my blood sugar levels are doing.

Personally I've found that ketosis varies with me day to day, and some days I'm more hungry etc, and have less energy then others. The energy fluctuations are nowhere near what they were before paleo though.

If I'm in ketosis, my BG doesn't rise at all (unless I participate in high intensity exercise). If your liver is dumping after fasting, it suggests to me that you are still glycogen dependent, ie not in ketosis.
