I read a while ago that consuming too much protein all at once will either extrete the protein through urine or convert it to fat. Is this true? If it is, how much protein is too much in a meal?
Asking cause I bought a weight gainer that serves a sht load of protein per serving (75g).

I'm sorry, clearly my writing was to small.
Myth.
Edit: Sigh...Your body can only utilise so much protein per hour, but that doesn't mean extra protein is immediately excreted, it's simply utilised throughout the day. The only time you're going to have eaten to much protein in one meal is if you consume more protein then can be effectively utilised throughout the entire day.

No.
Several independent labs have tested this. For example: Using two controlled groups, group A consumed 30g of protein per meal. Group b consumed 90g. All studies have shown there was zero significant increase in muscle or strength gains from the higher protein intake in one meal. I'd recommend 30-40 grams of protein at each meal every two-three hours of the day. Also, the body will not simply piss out extra protein. Any unused protein will be broken down and eventually will be stored as fat. That is not an opinion it is scientific fact.

Are you mentally impaired?
I said it was a myth and posted that there was no difference and then posted an article by Alan Aragon saying there was no difference...
And your idea of disproving what I said was creating a study which shows that...wait for it...there is no difference.
I think that deserves a round of applause.

interesting. was it that there was zero gains compared to the 30-40 g group? cause that would mean that both saw the same amount of muscle gain, which would mean that the protein wasn't wasted.

In this article someone asked Lyle is a person ate 5,000 calories, all from protein, would excess protein be stored as fat. He responded:
"Which means that the odds of protein being converted to fat in any quantitatively meaningful fashion is simply not going to happen. Certain amino acids are processed to a great degree in the liver (as I discuss in The Protein Book) and this can produce glucose, ketones and a few other things. But triglycerides (the storage form of ‘fat’) isn’t one of them.
I imagine that if protein were going to be converted to fat, it would first have to be converted to glucose and only if the amount produced were then in excess of daily maintenance requirements would there be conversion to fat. But as noted above, this simply isn’t going to happen under any even reasonably normal circumstances. No human could eat enough protein on a daily basis for it to occur.
What will happen, as discussed in Nutrient Intake, Nutrient Storage and Nutrient Oxidation. is that amino acid oxidation (burning for energy) will go up somewhat although, as discussed in that article, it’s a slow process and isn’t complete.
So, as noted above, while the pathway exists for protein to be stored as fat, and folks will continue to claim that ‘excess protein just turns to fat’, it’s really just not going to happen under any sort of real-world situation. Certainly we can dream up odd theoretical situations where it might but those won’t apply to 99.9% of real-world situations."ChemE in education, SoftwareE in job

There seems to be a misunderstanding. I was only disagreeing with the fact that the Op should not be consuming that much protein at one meal as it is a waste. The way I read you statement it came off as it's ok for the Op to take in 75+g of protein at one meal then not have anymore protein till way later in the day till he needs more protein to hit his daily macros. That is what I disagree with.

It's completely ok for the OP to have that much protein in one meal. It makes absolutely no difference.
And just for the lols, I'm going to quote your own study as evidence. According to you, both the higher and lower protein per meal group had the same strength/LBM gains, and that's exactly as it should be.
What matters is your protein intake per day, not how many meals you split it into.
Haha. You always know when you're needed

Exactly. My reasoning for breaking it up is this...
Having a constant intake of protein every two-three hours has been proven to maintain constant blood levels and keep insulin spikes under control. Since 30g is just as effective as 90g this allows you to break the meals up all throughout the day so you have much more constant blood levels an still accomplish your same daily intake of protein as someone who just consumes 100g in three meals 5+ hours apart.
Edit: I'm just using random numbers here btw just for the sake of discussion.

LIES and shenanigans!
Mr.B1G is somewhat right, although normally totally right (son, I am disappoint).
There is no method of storing amino acids for any extended period of time. So, whatever protein cannot be utilized it will be converted to carbohydrates and used for energy. If it still cannot be used, it will then be turned into fat. NO protein will be excreted through urine.
OP, don't take 75g of protein at once. TOO much. Space it out. Only way you could take 75g of protein at once was if it's a steak in a wholesome meal, but you couldn't eat that much.

I read the article. He seems to be talking more about absorption rates rather than utilization. He briefly referenced a small study about a change in body composition however that was only a 14 day trial and there are more factors to include. I am disappointed he only referenced that.
The body does not have a ridiculous demand for protein all day every day, it varies greatly through out the day as you know. Assume you consume 30g of protein from the pork which is absorbed at 10g per hour. Within the first two hours, your protein requirements for that timeframe may be met, the third hour is virutally useless protein which will have to be converted.

If so, I haven't read it. Doing so now though as that seems highly interesting.
