But if you're not taking in sufficient carbohydrates then even replenishing
glycogen will mean gluconeogenesis which does seem to involve cortisol in a
big way -- all I know is that I've been reading more and more about the
connection between high protein or low carbohydrate diets leading to elevated
cortisol levels as a result of its relationship to gluconeogenesis. When this
becomes chronic, insulin resistance and abdominal fat storage increases.
