Protein uptake/hr

Krikee

I was lead to believe that the body can only absorb 40g of protein/2 hours. Most meal replacement powders (MRPs) have 42g of protein in them. I assume this is to make sure that you get maximum absorption. Now, I have seen a protein shake mix from a company that I consider very reliable that has 60g of protein in a single serving. Was I mislead to believe that 40g/2 hours is the limit or is there some new science out there that I haven't heard about?

You were mislead. Everyone is different. A 90lb girl is not likely to be able to absorb as much protien per hour as a 250lb behemoth.

No protein ever really goes wasted. If you consume too much it'll just be converted into glucose. Its not smart to take 250grams of protein in one meal but spaced throughout the day. I say shoot for a 1.5g of protein per lb and for building muscle or losing fat look more at overall calories. Outside of that take in a 100grams of protein per meal if you want to but you'll be so full : P.

What's the best way to measure protein levels in cooked meals.

I was always told 1.5g per pound of lean mass...so pretty much your weight minus your body fat.

Or, just do 1g of your total weight if you don't know your bodyfat percentage.

Like others have said, your build will determine how much you actually absorb/process.

Another factor is how the protein is taken in. A protein shake made with water will be absorbed very quickly, where as a protein shake made with milk will be absorbed slower over time...iirc.

I don't think there is a good way to tell this. You have to know the nutrition information that goes into it.
I also heard that 1.5-2g/lb of lean mass is a nice amount of protein.
Does anybody have any idea what I could be confusing this with then? I've heard from numerous people (non-scientific but non-pro body builders nonetheless) that any excess protein ingested in a certain period of time is excreted through urine.

too much protein can fuck up you kidneys because they have to filter that stuff. So don't load up on like 250 grams a day if you' like 100 pounds.

Your kidneys filter protein and will pass extra protein your body can't use into urine. There is a danger of kidney stones if you do not drink enough water, take in too much protein, or don't space out your protein intake enough. You can also pass extra protein as solid waste.
