Nice post Robert!
If you're gonna count, I think 1gm/lb is like the recommendation for hard-core body builders. Too much protein will strain your kidneys and can get stored as fat (or so I've read). 0.5-0.8 is more normal persons range I think.
Also important isn't just what you eat but when...relative to activity and time of day. Mike Dolce (Dolce diet....mma trainer) gave us a ditty when he was here giving a talk. Generally, eat for what you just did, or for what you are going to do. Meaning, fuel up before hand and nourish for recovery after. Was poking more at the crowd of couch potatoes and why bad to chow down and drink beer while watching tv....it's not going to go anywhere but to your gut...ha ha.
Haven't dabbled in creatine or similar supplements for years, going for more plant=based natural nutrients.
Curious to know a bit more. What your energy levels are like pre/post workout both with or without the suppliments?
I like to whip up a smoothie in my Nutribullet, sometimes before or after working out, all depends on my time and place. Load up on veg (kale, spinach, mint, whatever else is on hand, fruit, and if it's post workout I toss in some non-GMO pea powder, lots of branch chain amino acids -- aka protein) to re-supply my body.
