I need to steer clear of the body building websites.
Layne Norton thinks insulin is the end all be all of muscle building, and recommends a pretty high intake of carbohydrates. I just don't feel right sacrificing health by eating a ship load of carbs for the sole sake of gaining a fractional amount of extra muscle, thus my questions. Reading Good Calories Bad Calories has really caused me to rethink my approach.. as well as Mark's Daily Apple, even though I find Mark's writing style to be obnoxious as hell.
Hey Steven didn't I see you on Strength Mill in the Mark Rippetoe forum?

The problems with insulin and carbohydrate intake are fairly well documented especially in excess... aka obesity in America. In fact, insulin knockout mice do just fine and actually tend to have longer lifespans than their counterparts.
(p.s. this is a very very very simplified view and is actually more complex than this & different in some cases but I think you get the point).
Basically, don't worry about insulin too much and it's better to keep it on the low side. As long as you're eating well, getting enough sleep and lifting heavy you will gain muscle mass and strength. Keep it simple.
Consider brushing up on exercise physiology (or anatomy & phys stuff) + an overview of hormones in your body from like wikipedia or something. That will help. Either that or read most of the forum posts here, and most of the blogs that some members have in their sigs like Mike's. You will learn a lot.
