I didn't know that about coffee. I only drink 2 cups per day, and it was never associated with my blood sugar rises. However I also inky drink decaf now because I had enough cortisol to drown a horse and I don't need the extra energy, and besides, I'm someone who strongly believes in living by the circadian rhythm. So even when I did drink caffinated coffee, it was never a first thing in the morning thing for me. I wouldn't take my first cup until at least a couple of hours after I was awake.

well, there's two things
one, is it contains sugar, about maybe equal to 1/5th of a teaspoon in every cup, maybe a little more, it is caramels though, so it's something between sugar and starch
the other thing is that paraxanthine, the main active metabolic byproduct of caffeine metabolism by the liver actually stimulates the conversion of fats to sugar, so it definitely does raise blood sugar levels, just not so much as actual sugars, but not zero, as you can see considering the two points, probably a cup of coffee is equal in blood sugar rise to 2tsp of sugar, and then you put another tsp on top...
"then you put another"
No I don't put sugar in anything. wtf
most people do though, i see them all the time... here in madeira it is standard to put about half a teaspoon of sugar into an espresso shot, known as a "bica", to the point where it's so common they just give you the sugar with an espresso shot, and a spoon to mix it in
