According to the Paleo folks, if you avoid protein supplements, you can go over the 30 or 40 grams that is normally considered the limit. Food protein digests slowly, compared to whey protein which digests quickly and may be excreted. I eat 60 grams per meal, 3 times per day. It takes roughly 200 grams of cooked meat to equal 60 grams of protein. I found a wonderful digital scale on sale for $11 and that is how I weigh the meat.
"They" also say, similar to Hunkmonkey, to eat some sort of carbs, like a little fruit or sweet potato, and some protein, though it does not have to be a whole meal, within 30 minutes of a workout.
