Hello!!
I am not a diabetic but did have gestational diabetes (this was recent though - I just had the baby three weeks ago). During my pregnancy I had fasting blood sugars very similar to yours (sometimes higher). I was baffled. How could my sugar be SO high after not eating all night? I was following the "diet" religiously and taking my massive doses of insulin four times a day. My sugar would drop into the 40's overnight and my fasting the next day was in the 150's! Anyway, enough about me! Apparently our bodies get used to having such high blood sugars that the liver makes more glucose than necessary. This is what makes the fasting sugar so high. When it starts to dip overnight the liver "compensates".
I'm glad to hear you aren't on diabetes meds yet! I honestly believe the insulin made my gestational diabetes worse. My sugars were still high after having the baby, which scared the heck out of me. I started Induction on 9/14 and my sugars came down and stabilized almost immediately.
If you follow the plan properly I am confident you can get rid of the diabetes! Good luck tomorrow
ETA: DUH! I didn't even address your question! I don't know much about glyconutrients. I just take a multivitamin daily.
