LEF coffeeGenic Green Coffee extract seems to work.
My blood glucose before eating was 80, after 45 min it was 125, 20 mins after that it was 108.
The same size pizza as before.
Yesterday before eating pizza BG was 93, 45 mins after eating 161, after another hour 112.
Of course, I will have to repeat a couple of times to see if it is consistent.
125 BG after pizza is OK.
The ultimate BG challenge, Olive Garden's Never Ending Stuffed Pasta (just kidding).
