I'm not sure I've tested myself enough to be sure. My fasting blood glucose on a ketogenic low carbohydrate diet--carbs under 20 grams, protein around 80 grams or lower--is generally somewhere in the 70's. With carbs under 20 grams, protein to appetite--probably around 120 grams a day--blood sugar was in the 80's or low 90's.
The highest blood sugar reading I've every had was 169, that was after eating seven bananas. That was sometime in 2013, I was messing around with carb refeeds using bananas. I've tried to do that with other foods like potato or oatmeal, but I seem to find starchy foods unappealing now. So I did the bananas for a while until I made the mistake of checking my blood sugar, and that put an end to that. I never really felt like I got anything extra in my workouts from the bananas, anyways. But very often they did trigger a whoosh, and my weight would be down the next day. Sounds backwards, especially since I went in glycogen-depleted, but that's what happened. If I was just watching the scale, I probably would have stayed with the bananas a bit longer.
But that's a lot of bananas. Maybe 175 grams of sugar?
I used to get reading during workouts as high as the mid-120's, once I went ketogenic, it's usually more in the 90's, that's probably due to physiological insulin resistance. I think things are messy, though. I'm using the term physiological insulin resistance here--but the increase in glucose could be due to lower insulin levels. Low insulin plus high cortisol/adrenaline plus high glycogen stores could equal a higher stress-response glucose output, where the same level of insulin and stress hormones paired with lower liver glycogen stores of a more ketogenic diet could make for higher free fatty acid release/ketone production. So maybe glucose intolerance would be a better phrase, since that's the only thing I can actually measure.
