I'm willing to accept it's complete bullshit, but I still get some carbs in pre-workout and some protein in immediately afterwards.
It's just a fancy name for being hungrier than normal after working out.
Even in my first year of training, I would stuff my face with food after training. And, I noticed I could eat considerably more on days I trained than when I ate at the same time on days when I didn't train.
Eating after heavy training just make common sense. I usually down a shake about 30 minutes after hitting the weights, while driving home. Within the next hour after that, I have dinner.
Is consuming protein and some simple carbs, post-workout a good thing? Absolutely!
Do you need cross-filtered, ion-exchanged hydrolyzed, smack-it-up-flip-it-rub-it-down whey protein, within 10 seconds of racking the weight on your final set? Not really!
Any type of protein shake (even soy), along with some Gatorade and a little creatine and glutamine, works for me.
