well speaking in terms of energy, I don't think it matters that much. Protein does have a higher themic effect than carbs (eating a lot of protein will up your calorie maintenance lever slightly). Eventually it's turned into ATP anyways. No of course, with regards to things like timing, controlling your insulin levels (not eating a lot of fast acting carbs like sugar) and stuff like that, the ratio of protein/fat/carb is important.
You want as much protein as the body can maximally use for anabolism. The problem is, you can't know exactly where this limit is. When does feeding the body more protein not increase anabolism any further?

Sounds good to me, just one of those wierd thoughts. I have another.
When people use the tern BV for protien.
Is that how much is sythesized into myofibrosis or how much is completely useed?
take beans for example:
BV is like 40 so most isn't sythesized would the rest go towards energy? kinda like the difference in Simple and complex carbs.

Biological value - Wikipedia, the free encyclopedia
that pretty much sums it up, I think.
I think you might want to look at the BV of the entire meal instead of the individual protein sources, though. I'm gonna ask Mreik on this one, he knows more about this than I do.
These are some questions that come to mind:
The wiki article says this:
Now if EAAs are the primary cause for "bottle necks" in the protein synthesis, then surely if you have two protein sources in your meal, both are of low biological value but together they all contain all a lot of the EAAs, that bottle neck would not occur?
Also, if I eat a meal at 4PM with incomplete protein, but I ate a meal at 1PM, also with incomplete protein, but together these meals contain a lot of all of the EAAs, will that bottle neck still occur? How long can the body hold on to the amino acids "waiting" for others to come along so it can produce the protein it wants to?
If everything is "reset" between meals, meaning that protein synthesis only depends on the amino acids you ingested within the last hour or so, then I guess you'd want to make sure you get all your EAAs in every meal. however, if that's not the case, and protein synthesis can use amino acids you ingested maybe 4 hours before, then getting all the EAAs in every meal would not be all that important. And if so, then I guess breakfast would be the only meal where it would be important to ingest all of the EAAs (unless the body can actually hold on to EAAs since the last meal you ate the day before)
I hope all my premises and conclusions based on those premises makes sense? I just need to know what the premise for this actually is. Where is the biochemist when you need him?

Exactly.
This Q is loaded. I'll assume you mean each meal has got EAAs but neither has all 9. Number one factor would be the type of meal this was eaten with. Things that delay gastric emptying would obviously help the situation, to prevent the amino acids from reaching the duodenum too early before the next meal. Examples of thigns that slow gastric emptying and would increase the likelihood of all the amino acids being utilized are: low pH (<2 in stomach; <2.5/3 in the duodenum), hypertonicity of the contents, fats in the stomach/duodenum, amino acids in the duodenum, duodenal distention (how long it's been since you've eaten), and some non-duodenal factors also. This also depends on the type of protein, which I'm sure you knew. Levels of somatostatin/glucagon/insulin/cortisol/epinephrine in the blood, which would help determine how quickly these amino acids were being taken up. Also the state of the body, as I'm sure you know amino acid uptake it upregulated during times of high BGL. Nitrogen retention is a funny thing, some studies actually show that the more you take in, the higher percentage you retain (which goes against the norm). So the actual amount of protein in each meal could play a big role, along with your regular habits of protein intake. So, overall, I have no idea how long. If I had to take an educated guess, I'd say within 3 hours you'd be pretty well off. More than 5 and you're not looking to hot. (<-Quotes from the magic 8ball)
It definitely wouldn't be able to keep any considerable amount for that long of a time. But like I said before, it'd take a while to 'reset'. Adequate time for MMCs and whatnot.
He's right here you flippin viking.You need to get your degree already so I can ask you stuff since you'll have all the NEW info.

Your body's lazy. If you give it enough carbs, it won't use the protein for energy because it's difficult. The best bet is to get your 'energy' from carbs, but to take full advantage of the energy (high BGL) by also taking in protein. So.. both?
