It seems that many people are to concerned about the GI of carbs when the Glycemic Response (GR) is much more important to an athelte.
GR (the actual glycemic response once it is actually ingested is of far greater importance that of a simple GI rating). Low glycemic meals and high protein stimulate the release of glucagon, a hormone secreted by the alpha cells of the islets of Langerhans in the pancreas. Glucagon activates adipose cell lipase to make more fatty acid available as energy. Remember that FFA (free fatty acid) play a huge role in relation to muscle. Low serum FFA levels increase muscle glycogenolysis (muscle breakdown). The stimulation of glucagon with the amino acids (from the protein) and their interaction with insulin create a "controlled" insulin secretion - therein harnessing more anabolic attributes of the insulin activity than if insulin secretion was stimulated by carbs alone. GI is only half the story.
