Maximum amount of protein absorbed at one time

As always, thanks! You give me such hope!

I can't wait until your little one is here.

I just researched this protein question the other day (googled "protein maximum grams metabolized") and I think the consensus is that you can metabolize all the protein grams. If you think about it, it would be counter-intuitive not to metabolize the grams of protein--if that were the case, there would be no fat people in the world--they would all just eat over 25 grams of protein at one sitting, ie, tons of ribs, steaks, chicken, etc and never gain a pound of their consumption. But read up on it yourself, it is pretty enlightening. When I was reading all about the Lewis and Clark expedition of discovery of the NorthWest, it was amazing!!!!!---as all the men were expending so many calories per day in hoisting boats, trudging terrain for miles, etc that each one of them would sit down at dinner and eat about 12,000 calories of deer, elk, bear meat at one sitting. And they were well-nourished and healthy men. I don't think any of them ever heard of this protein rule.

I agree with onehappygirl.  I've been told 25g per meal.  With that being said, if you are in the gym and trying to bulk up as some of my friends are it's a totally different story.  They work out approx 2 hrs twice a day.  3 hrs on weights and 1 hr cardio.  They consume a minimum of 1g of protein for each pound of weight.  For the average person who doesn't work out like that, they excess protein would just turn to fat.  However for someone utilizing it, it will turn to muscle. 

My physician told me this week that we eat the way we do because that's the way we have always eaten.  Back in the day (Louis & Clark time frame), we farmed and did manual labor all day; therefore, we consumed high amounts of carbs and protein.  Over the decades we changed from farmers to office workers and don't exert nearly the same amount of energy in a day that a farmer does or once did; however, we still eat like we use to.  Our work changed but our eating habits never did, hence we are an overweight population...

I am a 'double=up' person , trying to get half or more of my protein in early, using double protein powder. And I'm a cheapskate. So when I saw the first post that 'we can't absorb more than "x" grams at a sitting, so more than that wastes your money and doesn't count",  I hurried to try to find actual scientific evidence, with references  to support that statement. Trying to get past all the body-building and fad diets sites to get this info is tough! And I'm very good at finding information, but just don't see anything to support the idea that the amount of nutrients of any type you can absorb is somehow limited, unless you count someone who eats SO much that their tummy gets upset and the body purges, from whichever end.
The best I could tell from what seems like scientifically tested info is that the amount you can absorb PER HOUR varies according to the type of protein and also whether you are resing or working hard after you eat it. But the protein does not just pass through unused, it does eventually get metabolized though it can take a while.
I may have to search on this some more later, just to fully satisfy my curiosity.

Take a look at the sites I posted and see if they help with your research.  Good luck.

Take a look at the information I found on the following sites.  I think it will help all of us, especially those looking for some type of scientific evidence. 

How to Calculate Your Protein Needs:

1. Weight in pounds divided by 2.2 = weight in kg
2. Weight in kg x 0.8-1.8 gm/kg = protein gm.

Use a lower number if you are in good health and are sedentary (i.e., 0.8). Use a higher number (between 1 and 1.8) if you are under stress, are pregnant, are recovering from an illness, or if you are involved in consistent and intense weight or endurance training.

Example: 154 lb male who is a regular exerciser and lifts weights
154 lbs/2.2 = 70kg
70kg x 1.5 = 105 gm protein/day
