how much protien can your body handle at once

Right now I'm a Nutrition (Dietetics) undergrad and I totally identify with you... the protein intakes that the texts books I'm required to read just piss me off. No matter how you look at it, a 50 gram protein RDI is not going to put on any quality size for an athlete.

But at the same time, there is a point of diminishing returns with protein intake in one sitting. And the Shaq argument is totally on base.

One of our nutrition teachers, in his lecture powerpoint, was going over protein and made the point of bringing up how "un-needed" protein supplements were. He of course, made his point by displaying a picture of the Governator in his bodybuilding days and saying that this was more due to the steroids than his massive protein intake. I just about ran across the lecture hall and slapped him. Once he goes off the juice he's still going to need more than 50g of protein to support his gains. I dubiously reject any science that says a 250 lb bodybuilder is going to maintain his muscle at 50g of protein a day.

Sometime later this day I'll post some of my favorite passages from one of my textbooks. There are real dandies in there.

haha good post i had a teacher say something very similar i wanted to slap him for the comment he made so i hear ya man and good thread too i was curious so magic number 50g a sitting
 
well, type of protein as well as what it is eaten with affect both absorption time from mouth to bloodstream as well as clearing time from bloodstream to bowels/bladder. Egg protein happens to be the most studied and if you were to eat just egg white protein for a meal i dont care whether you eat 4 eggs worth or 40, you aren't getting amino acid usage out of more than 25g worth. Cottage cheese on the other hand is mostly caseins which have about an 8-10 hour life in body, and usage rate of it is somewhere from 6-8g/hour

so what does that mean? is cottage cheese better?
 
define better, and i can answer that. its better in some ways, not so good in others. 10g of whey isolate taken every hour is probably better, but a pain in the ass. or 5g of EAAs with a correct ratio taken every 30 min is better. But whats funny is you reach with those a point where the fast action of the protein starts to turn the body to burning protein instead, so at 30 days the difference of the guy doing the whey every 60 minutes vs casein every 8 hours is minimal.

better to eat all whole foods, and add a little extra leucine or bcaas

i guess the only way I can define better would be for me in my case Im cutting right now trying to lose fat and sort of a recomp. Im working out 6days a week and doing cardio on those days as well.
 
so you aren't looking to spike anabolism, but moreso stave off catabolism.

I'd honestly think (and plenty of people here will argue with me i'm sure) that your best bet would be 50g of protein from casein every 8 hours whether shakes, calorie countdown milk, cottage cheese etc, and concentrate on lots of leafy green veggies + healthy fats for meals

alright, ill try to get some cottage cheese then soon. Im using 100% gold standard whey right now. whats difference between casein and just whey?
or no difference?
 
huge difference :) whey's absorption is about 8-10g/hr but no longer than 3 hours of positive nitrogen retention from a single meal. if you use the whey, i'd use smaller servings ever hour - 90 min, and add some fat + fiber to it to slow it down.

and keeping sustained protein in my body does what?

sorry, i think you might have answered this but this is VERY new to me.
thanks for the help!

It raises the amount of amino acids available to the body so muscles cells are less likely to be catabolized for their amino acids or gluconeogenesis.

oh ok, thanks alot for the tips guys. So for a recomp I need to have sustained protein through my body. K, ill fix my diet to encompass that.
 
it just makes it easier, and if you aren't trying to bulk then you are less concerned with trying to spike the body into adding a bunch of new muscle, mostly you are trying to hold onto what you have, with some small gains
