The (natural) human body can only process 10 grams of protein per hour.

That post is filled with fallacies.
True premise: Net protein balance reaches its maximum from consumption of ~20g of protein.
False conclusion: Therefore, you should spread your protein intake over the day.
Correct conclusion: Eating more protein than 20g in one sitting does not elevate net protein balance further, but it does extend the duration your meal provides your body with protein.Scientific author, fitness model & online physique coach

No.
Whey iso is digested over 1-2.5 hours.
Given the human body has a rate limit of 10 gram/hour on protein absorption, that means if you take in anything over 25 grams of Whey iso in those 1-2.5 hours it is likely converted to carbohydrates.
If you were to take this protein in any other form (eggs, milk, meat) hell even Whey Concentrate (increases digestion to like 2-4.5 hours) then it would be a different story.
Basically, people are wasting time and money if they slam 2 scoops of Whey iso before or after a workout.

Hi Tussmann,
It depends upon what you mean by "process". There is in fact no known limit to how much protein the body can absorb into the bloodstream from the gut. In healthy humans, even very large servings of protein are almost entirely absorbed and virtually none is found in the feces (unless it is from a low-quality or fiber-bound source of protein).
I think what most people want to know is how much of that absorbed protein is "retained" in the body as new muscle. The vast majority of the protein we eat is of course not retained as new muscle (or some people would get as big as a house in short order) but on the other hand, scientists have shown that one of the biggest activators or protein synthesis is the level of amino acids in the blood and high levels of amino acids in the blood are best achieved with a fairly large serving of quickly absorbed protein - like whey protein or amino acids.
Of course very large dosages are probably not advantageous. Some research suggests that 20 grams may be enough to maximally stimulate protein synthesis but other studies have suggested that dosages much higher than this may have added advantages.Mark Gilbert B.Sc (Nutrition)

Meal frequency only affects protein metabolism acutely. In the long term, it is irrelevant.
