I currently consume very little plant matter to prevent spikes, since my body can no longer metabolically process carbohydrate in a normal way. Basically I just don't give it a fuel I know it can't properly deal with anymore. So what I want to see an hour later when I test is little or ideally no change in BG. Protein can have some effect on BG because it requires insulin to process, triggering the simultaneous secretion of glucagon with the insulin to release liver glucose from stored glycogen to prevent BG from dropping dangerously low in the absence of glucose-containing foods during the protein meal, which is exactly what should happen. If a huge spike of glucose from liver glycogen stores gets dumped at once, something must be out of whack in the system but I'm not familiar enough to know what.
