I'm not saying it's the best decision but I would rather take in more than less and secrete some as it states there's always some protein in urine(how much is obviously dependent on persons height/weight)

Also you were the one who brought up the 500g dose of protein earlier then you want to go back and say how hard it would be to not only consume that much but digesting it and utilizing it would be damn near impossible...which = spill over.... More common then ya think...

Proteinuria is NOT too much protein taken in. It is excess protein found in urine. It can be a sign of diabetes, kidney disease or failure, pregnancy, etc. Many causes of this are indicative of an unhealthy individual but you're right not all cases. Working out can raise your urea and that's not dependent on protein intake. Neither is heatt exposure, stress, etc.

I also see where you're going off track. Urine protein tests measure serum albumin a protein synthesized by the liver. Albumin protein is NOT the same as dietary protein. Look into this as this is where I think you're missing the point. High dietary protein intake increases the liver's synthesis of a serum protein called albumin. When you do urine tests they measure for albumin NOT dietary protein. So there is no spillover as you're calling it of dietary protein as that's not what's being measured or tested for.

I also don't recall mentioning 500g of protein in this thread. I mentioned 500g of carbs and DNL but of you could quote where I said that so I can follow you is appreciate it.

Like I responded to NACH3, urinary protein is albumin which is NOT the same as dietary protein. There's a huge difference between the two but you're using them interchangeably when they aren't interchangeable.

Ok... But everywhere I look, it says that P(along w/any other macros) if not digested and utilized it will be stored away as fat until it's burned as fuel...

And this is where I think your referring to the 500g of protein

"One CAN utilize 500g of protein regardless of bodyweight. Do you have any idea how long it would take the body to digest all that and then absorb and utilize it after digestion? It would take 5+hrs for it to digest. The ileal tract is the digestive system's natural brake. It slows and speeds up digestion based on meal volume and macro composition. Protein takes an incredibly long time to digest especially 500g of it. What happens is the amino acids get used to replace what's lost from proteolysis, gets used to build new muscle tissue, or gets converted to glucose to be used as energy via gluconeogenesis. Unless you mean stored in muscle tissue as muscle protein does not get stored anywhere else nor does it get expelled via your urine."

And does get expelled through urine... But I see where you are going now moreso...

Ah OK thanks for the info :-)

I see it everywhere too but it's incorrect. Watch the Will Brink video I linked and he'll explain how it's theoretically possible, realistically it ain't happening.

I see it now, but I only brought up the 500g of protein bc you mentioned it in the post right before mine. I also never said it was hard to digest and utilize just that it would take a long time for it to happen precisely bc the body doesn't want to expel anything or waste anything. It takes as long as it needs to to get all that it can nutrient wise from our food.

Ok... I was thinkin you had access to something I didnt! Lol Thus why I was so adamant about in excess your body either stores it/& or expels it... It eases my mind that you/we are seeing the same things... Lolz

Thank you for making this clear.
