would be *before* you ate anything... preferably 6 to 8
HOURS BEFORE you ate anything, and then
TWO HOURS AFTER you ate. 5-10 minutes after eating whole-milk (regular) yogurt [I eat yogurt, I read nutritional lables, if it had 17 grams of sugar, and IF you had what the nutritional label stated as ONE SERVING which on a yogurt label is usually 4 ounces, then it was 'regular' plain yogurt] you STILL can't tell anything about your actual diabetes status.
My best guess...
