Retarded idea

From whence did the crazy idea that you can only absorb 25-30g of protein per meal originate? :confused: does anyone actually believe in it?
 
In The Bible

Just joking. I can't remember the exact gist of it, but you remember your HS Biology where they filled a glass to the brim with water and then told you to see how much sugar you could put in it without it flowing over. It was quite a bit. Anyway the explanation I heard had something to do with the blood volume and the amount that could be absorbed before the circulatory system became saturated. They didn't figure in the carbs, or fats though. It all sounded kind of hokey to me.

If it were me I would have said 50-60 grams. And got that rumor going. That way the supplement manufacturers could sell more protein. And I'd be trashing beef, chicken, fish, eggs, etc. Bad, bad, protein.
Causes intestinal polyps due to malabsorption. Get the picture.

This whole thing about protein absorption is a lot of bunk. Look at the length of the small intestine. Now they say that if I take more than 30 grams it's wasted. Where does it go? Does it sneak out of the system by magic. I figure it just stays in the small intestine and when there is a shortage in the blood it enters.

We're not like chickens. They feed them so much protein that some of it never gets digested. They were remixing it with their feed and sending it back through them. There was some big controversy with that so they started selling the 'chicken shit' to the cattle ranchers to mix with their feed.
 
i agree with it.... thats why multiple meals are more
effective than just 3 large ones...

your body is able to digest and absorb certain amounts
and your metabolism can accomodate accordingly.

too much of anything can be bad (except sex)
 
Here's a fairly long thread on the subject in MFW:

The basic consensus is it is just a myth. No one has been able to back up the claim with any real evidence, studies, etc.

There doesn't appear to be anything to the 6 meals a day thing either, other than it may help with appetite control. As far as fat storage or metabolism, it doesn't appear to have any affect. Another thread on MFW:

Can't believe it isn't in the Bible :)

thank you to everyone for the thoughts so far.

i'm not sure how to specifically identify 'absorb'. maybe 'from a single feeding, the body can only successfully utilize that amount of protein AS protein, as opposed to turn into glucose, break down & excrete etc. '...

i guess i had two problems from this without understanding the science behind gastric emptying time, the absorbtion rate of the small intestine etc. etc. - firstly, one of instuition. it's far too easy to eat more that 25g measly grams of anything, and everyone does it. secondly, highly simple maths - how does a 250lb athlete get his 1g/lb - 1.5g/lb in 25-30g lots? you'd have to eat all goddamn day.
 
I wonder why no one ever says " you cannot absorb more than 10 grams of fat every 3-4 hours" or " you cant absorb more than 50 grams of carbs every 6 hours" , man that would be great.
 
If you have a couple of hours, you can check out Lyle McDonald's 4 part article on Protein:

Just my opinion, but it seems that the rate of digestion of the protein is really the issue. If you are getting most of your protein from solid food, it probably doesn't matter nearly as much. Whey seems to digest much faster, and might be the exception, which is one reason I only use whey usually right before and after workouts.
