Answer

Hi Brian,

Sorry to be a wuss, but I cannot touch this question with a barge pole as;

1. I am not a medical doctor
2. Any research I have done on this can be replicated by yourself.   Further, someone living with diabetes will understand the medical complication more than I will
3. If I get anything wrong, I would feel horrible for misleading you or placing you at any extra risk

I do know that almost all German Pilsner style beers do not have added sucrose sugar & contain only sugars extracted from the malted barley.   They are also fermented to a degree that leaves very little of these sugars left in the beer, creating a stereotypical dry characteristic.

Many cheap beers (& many expensive brand names which are none-the-less cheaply made beers) contain corn syrup & sucrose which may not be fermented completely out to leave a residual sweetness.

I do know that alcohol lowers blood sugar levels making drinkers more susceptible to a late night snack.
