I am T2 diabetic on 1000 mg Metformin daily. Eliminating refined sugars, all grains, and funky seed oils from my diet has lowered my glucose readings significantly. I am now enjoying numbers below 120 two hours postprandial, which is a first since being diagnosed in Dec 2010. (I never had crazy, out of control numbers that usually lead doctors to a diagnosis. I tested my levels on my own out of curiosity when my sister was diagnosed with gestational diabetes and tracked it for months before contacting my MD.)
What I am having difficulty with is my fasting glucose reading I take upon waking. It ranges anywhere from 117-150. The body releases hormones to prepare the body for the day, causing the liver to release glucose to get energy flowing, and mine seems to be a little too ambitious!
Has anyone had any success lowering their fasting reading?
When I was T2 my fasting was at 200 steady, and who knows how long it was at that level before I started testing. Reducing my daily calories to 1500, and restricting the high glycemic carbs (sounds like you're doing that - the worst for me was rice or dry cereal), helped immediately on getting my fasting numbers down. I could still spike post prandial up to 200 though. Getting my weight down helped get rid of the T2 altogether. I've postulated that my big waistline - all that visceral fat packing my organs - was the root of the problem.
I've wondered this, too. I am not T2 diabetic, but I have highish morning fasting blood glucose: mid to upper 90s, whereas my postprandial blood glucose is lower mid 80s. I read somewhere that it's an indicator of liver insulin resistance (as opposed to muscle or other tissue insulin resistance). So maybe try some liver support (silymarin from milk thistle) and see if that lowers your morning glucose readings?
Cold Thermogenesis a la Dr Jack Kruse style consistently drops my fasting blood blood sugar readings by 10-15 points. I am not diabetic, but I understand many Type 2 diabetics that post on his forum are seeing the same kind of results.
Your fasting #s are too high if they're consistently within that range. But you should always compare your fasting #s to your A1c, so that you know where the spikes are coming from: post prandially or from generally elevated fasting levels, which could be due to many things.
So it's hard to interpret your FBG #s alone without putting them in context with your A1c #s. How good is your overall BG control? Does your FBG reflect your overall BG control? Or is it an anomaly? Depending on your answer, there is literally a binary tree of expalnations about what your elevated FBG could mean.
