over the past couple of weeks i’ve been getting familiar with what my fasting and 1-hr, 2-hr post-prandial glucose readings are.
(in mg/dL)
during extended fasting: 50-70
normal fasting: 80-87
1 hr pp: 90-120 (depending on what i eat)
2 hr pp: 90-110
so when i eat a home-cooked ketogenic meal my glucose barely peaks and remains relatively steady, like 85, to 95, then to 90.
but recently i started VSL#3 DS, a probiotic which contains maltose. i emailed the company and got the nutritional info for it.
yesterday i took 2 packets (~13g total carbohydrates) with about 1 tbs of sour cream right before my meal (beef with korean fermented bean paste cooked in lard with green beans)
i measured glucose & ketones
fasted: glucose 86 mg/dL, ketones 5.3 mmol
1 hr pp: glucose 92 mg/dL, ketones 5.5 mmol
2 hr pp: glucose 93 mG/dL, ketones 3.5 mmol
i did not do any activity and sat on the couch during this time. so i noticed my glucose remained very steady but then ketones dropped at the 2 hour mark. Can I test post-prandial glucose + ketones in this manner and somehow use that information to infer what my insulin response is to certain foods?
background info: 27 yo female, diagnosed pre-diabetic, borderline diabetic in the past, PCOS. ketogenic on and off past 4 years, stuck with it since July 2017 and down 40 pounds this year (currently about 142 lbs). most recent HbA1c from August was 5.0% and fasted insulin was 6.2. i’ve taken metformin in the past but not for the last 4 years. i currently fast 2-4 days a week, and estimate that i’m between 27%-30% body fat (only have a hand held body fat monitor)
the reason i’m interested in this is because if glucose numbers stay steady it’s difficult to determine whether i can tolerate things like sweeteners, the maltose in my probiotic rx, etc.
for example, i had one outlier 2 hr post-prandial of 140 mg/dL and i suspect that’s because a bit after my meal ended i took the VSL#3 as a shot with water, and not mixed with fat/protein. don’t know what my ketone readings were that day however.
TIA!
