The ingestion of protein stimulates both insulin, and paradoxically
glucagon -- too bad these researchers didn't measure glucagon. It is
because protein elicits a rise in glucagon as well as insulin that
prevents one from experiencing hypoglycemia after a meal rich in protein
but low in carbos. If insulin was the only player after a protein rich
meal it would drive blood glucose into the cells causing a sudden drop
in plasma glucose level. However, protein also increases glucagon which
induces hepatic glucose production (breakdown of glycogen) -- thus the
hypoglycemic effects of protein (insulin) are counterbalanced by its
hyperglycemic effects (glucagon) and the net result is a nice steady
glucose level that prevents hypoglycemic starvation of the brain during
the absorptive period after a meal high in protein, but low in carbs.
