I am a physical culturalist and had always followed the bodybuilding crowd until I encountered the paleo crew through incites provided by Vince Gironda, an old school bodybuilding guru. My question is: Is a "post-workout recovery shake" needed to maintain muscle mass after an intense bout of weighttraining and cardio? Can whole food protein be sufficient or shoudl one include a "fast-acting" protein source after a workout in addition to fat(such as cream and/or MCTs)?
Post work out, I would stick to l-glutamine and some tuna. I would take the shake before bedtime so your body doesn't catabolize your muscle in your sleep. (I hope its free of any "uppers" like Creatine that might interfere w your sleep.)
i make sure my PWO protein shake has a higher ratio of the amino acid leucine so that it maximizes and potentiates the anabolic state my body can achieve. For me, creatine DOES make a noticeable difference on my endurance.
I've had great results in my training so far - though to be honest, I've changed up a lot of variables in my diet recently so I can't really pin this as the cause of my progressions.
I think its worth giving it a shot - a bag of protein is cheap and may give you tremendous results. If it doesn't, eh - just toss it.
Best of luck!
