True but after a long nights sleep he will have lowered his glycogen stores (especially with the cardio and the deficit) and with a low gi carb I doubt much of an insulin spike will occur. I mean we want an insulin spike to stop from burning through LBM, but its not supposed to be a candy bar... He would have to have elevated blood glucose levels for the body to release insulin and after a fast and a low gi food... Fire what do you think?
PS. Remember this is resistance training too guys, not just cardio.
