Slightly increasing carbs & better BS?

Hi folks,
I'm prediabetic and been following a very LC (ketogenic? <50g net) diet for over a year. Was pushing the too-skinny line and feeling tired after exercise so I thought I'd try to increase slightly to more "typical" low carb (net 50-100g/day). I think I'm feeling somewhat better, stopping the weight loss and actually having *better* blood sugars. Has anyone else been though this? I'm guessing it's because a little more carb is stimulating my pancreas to release more insulin (I don't think I'm very insulin resistant; no "metabolic syndrome" signs and lowish c-peptide)? Anyway, I mostly wanted to check in because, while it's lovely to let myself eat an apple, few bites of yam, or a couple wasa crackers with almond butter, I am wondering if there are any caveats or pitfalls to be on the lookout for. My stomach has been extra rumbly with this, but that could also be because I've been paying too much attention to that US election...
Thanks!

Well, my fasting #´s have been better, and they were my nemesis on a very low carb diet. (Better for me = high 5's.) But I may be having some unfortunate postprandial tradeoffs--or at least I did last night. So frustrating that every time I think I've figured something out a new catch emerges! I'll try this for another week and see what picture emerges, I guess. It is so lovely to go to bed not feeling hungry! But, we shall see.

Just by way of an update, 6 wk later I had my quarterly bloods, and although I've had a bit more in the way of symptoms (mostly just the feeling the postprandial highs, hand/foot swelling, thrush), neither fasting nor HbA1C have changed. So that's good, I suppose. Going to continue to let myself eat up to 100g/day carb and see how things continue.
