One reason that you want to take in fast digesting or high glycemic carbohydrates is to replenish muscle glyc as quick as possible to help set the body in a state perfect for muscle anabolism not catabolism. And insulin does take part in this and not in a bad way. Insulin is very anabolic (why do you think bodybuilders inject themselves with it). When the body is in an energy depleted state insulin does not neccessarily lead to an increase in fat storage but aids in protein synthesis which is another role because of the increase in release of testosterone. This is where protein and BCAA's come in (whey is my prefered choice because it is a fast digesting protein but having a mixture of fast and slow can be helpful). You must have these to start the repair and synthesis of muscle tissue (actin and myosin). It must be from the diet or the body will go catabolic instead of anabolic. Besides breakfast this is the most important meal of the day followed closely by the preworkout meal cause you need energy to lift that Fn heavy weight. Personally I like to chug my cell tech carb control by muscle tech and post workout recovery by Advocare for my cool down (which means I have just got done lifting). then I shower up drive the 6 minutes to my house where I have everthing already made and approx. 60minutes after I get home eat a good meal to keep my body in a prolonged anabolic state cause it is still digesting my immediate post workout meal. For this secondary postworkout meal I like the staple bodybuilder clean foods. Chicken, brown rice, and broc, or the oaks fave Steak and potatoes with some kind of fiberous veg.
