Tell me about low carb = higher FBG

Ive seen a lot of people here say that their fbg is higher on low carb.

Any theories as to why? Any evidence based studies that explore this topic?

There is also the theory that your body raises gluconeogenesis (conversion of protein to glucose by the liver) in order to be able to supply your brain with glucose. Couple that with the effects mentioned by MathGirl and my FBG is about 100.

My paleo-friendly doctor is not worried, though I am sometimes.

GNG is the conversion of non-Carbohydrates to glucose. It can be fat (what we eat or what we store), protein, the breakdown of muscle tissues, whatever. If there is not enough protein or fat in our diet, our body will start to search for materials elsewhere (like muscle tissue and body fat). We will die of starvation long before our brain runs out of the necessary glucose

Got that, but back to my original question, is elevated FBG common in low carbers in general, and if so, is gluconeogenesis the reason? That presumes that low carbers have insufficient glucose from dietary sources and overmake it via GNG during the night. If that's the case, would ingesting carbs before bed LOWER FBG because there would not be a need for GNG to make more carbs?

Are there any studies that suggest this?

I'm just trying to understand. I have elevated FBG intermittently. I didn't test before going low carb, so I have no idea if I had elevated FBG on SAD--I was eating so many carbs I would expect my BG was ALWAYS elevated then, but I'm just guessing. What I'm trying to sort out is whether my currently elevated FBG's are DUE to low carbing, or is it just my deranged metabolism in general.

And, if it's due to low carbing, is there any value in increasing carbs (perhaps at night) to avoid the cause of elevated FBG, or is it just a somewhat normal adaptive physiological response that does not need "fixing"?

My FBG's aren't that high--usually 100 to 110, but with occasional spikes to 120 - 130. And I'm more often in the 80's or 90's. So I'm not super worried, more curious than anything else.
