^ Good post.. Of course pre/post nutrition is just the tip of the iceberg leading to OCD the most rediculous of things. I remember things like, "The very second you wake up, drink whey and water because of you being in a fasted state during sleep lol."
Honestly, it really hinges on the diet itself as well as how well you handle your carbs. Of course most importantly is your GOALS itself. If you're massing, then of course liquid carbs would only help whereas if you're a member of "used-to-be-fat-aholics" like I was, then you really don't need the spike.
I've personally known quite a few bigg'uns that don't take ANYTHING postworkout because they've had their BCAA's during the workout.. So 30 minutes after hitting the weights, if you're eating a chicken breast with sweet potatoes, then you're good to go.
Matter of fact, I think there's quite a few free e-books from Scivation out right now that are really quite "no insulin spike needed" that are surprisingly easy reads for anyone interested.
