I am an idiot, so here we go.
According to my limited knowledge, insulin is a storage hormone. So in theory, if we spike insulin it could blunt cortisol production and perhaps drive more nutrients into the muscle (if the individual is insulin sensitive enough. Wouldn't a individual maximize his muscle gains if he eats something high in Glycemic load (ex. one or two pieces of chocolate) before his meals? Perhaps even some high GL food in the morning to blunt the sky high cortisol levels?
