They are not the same mass so the recommended amount would be different. therefore what would be spread over 5-6 meals would be different.
Also, you will probably agree that a 250 lb person will have to work a lot harder on average (a statistical concept) to maintain his leanness and muscle than a 140 lb person (although I think this comparison is a tad unfair if we considered the same height body type individuals). Regardless I would argue that given evolutionary constraints, it would be rather difficult for a person who is say 5'10 to maintain a 250 lean physique so there would be no reason for bodily processes to ever be selected to handle eating huge amounts of protein at once.
I wasn't really talking about leanness. I was referring to how much protein could be absorbed in one sitting. In that case the example is a good one - there's just no way a 250lbs powerlifter will absorb the same amount of protein per sitting than a 140lb badminton player. Doesn't need to be a big PL guy vs smaller badminton guy, put any big guy with a lot of mass up against the opposite. It doesn't matter how mismatched they are or unfair it seems to pair them, it's only in reference to how much protein can be used. The 20/30g or whatever it is is just far too specific to be true.

I never meant to say that you couldn't use more than 20g in the sense of it would go to waste. I was just saying that studies seem to indicate it is just "excess" generic calories that could be used if you want to fill the bill of your energy requirements but would not somehow give you a better ability to gain muscle. Basically, if you are consuming 20g per meal, that is all you need for maximum muscle gain.
Yes but, assuming that's true, which it may well be, is 'muscle gain' the only reason we need protein? The PN link I posted goes into more detail...
Also, if you're 'pro low carb diets' and also buy into 20g per sitting of protein then, you contradict yourself.
Take 6 meals with 20g each meal - 480 calories.
Lets say you need 3500 calories per day. You know you need this because you feel like crap in the gym if you eat any less (which is how I judge it - I don't really 'believe' any goverment RDA). Anyway, look at those numbers and your protein intake is about 14% of your daily intake.
Point is, by buying into the 20g per sitting thing, you're limiting yourself in terms of macro break down. Unless you go very high fat then, you're stuck with high carb diets and, we all know how good high carb diets have been to us over the last few decades. In this case, in my view you would be better off going high fat than high carb but regardless, the point is, when you apply the 20g per sitting logic to other scenarios, it just doesn't make sense.
Again, as per the PN link, muscle gain isn't the only reason we eat protein.
