Comments on: What Are Good Sources of Protein? – Amino Acid Profile Part 1

most people on forums say glutamine is worthless at low doses (they say megadose 20g+) because that was shown to work on burn victims in some study. Some people swear by it though.

Important to keep it in the context of the section heading which was:

Meeting Basic Bodily Requirements

in that specific context, pretty much all foods tht contain protein meet the amino acid requirements of humans. And carrots and onions aren’t massive protein containing foods. The chart demonstrating this (showing AA requirements for adult humans compared to the AA profile of a variety of high-quality proteins) is in The Protein Book. Basically all proteins (of even moderate quality) exceed human requirements. thus there is no functional difference. Eat sufficient total protein and you’re fine from the standpoint of meeting basic bodily requirements.

Again, carrots and onions aren’t major protein containing foods so that’s just a stupid example.

“But from the standpoint of amino acid profile, there isn’t much of a functional difference between proteins”

so whey, soy, carrot, onion… you really mean this?

Lyle, I think I read in one of your works (UD2.0?) that it may be beneficial to take some glutamine right before bed. I think you said it may help with HGH production? Can you comment more on that aspect of BCAAs, and why that may be better than eating some meat right before bed? It would seem to be relevant to the BCAA discussion, though perhaps you will discuss it in Part 2 of this series. Thanks.

Go to medline or get the Protein Book, all of the research is in the latter. Or go to my forum.

This isn’t the place for this.

Thanks for very quick response! I would like to see studies that say that carnitine is useless for fat loss.

As for carnitine and androgen receptors, I see that you didn’t criticize it, so I assume it’s all good to use it for that

Barry

This is how I do things.

If you don’t care about the science, don’t read the articles until I wrap it up at the end.

Clearly the rest of my readers don’t agree with you so (or they haven’t taken time to say so) so you might see why accomodating you (and ignoring what they want) isn’t very likely to happen.

How about cutting to the chase? Provide everyone a list of good protein sources. Provide a list of protein sources to avoid. Honestly I could care less about the science.

I was specifically speaking about fat metabolism. And oral supplementation doesn’t work to increase fat metabolism because it is ineffective at increasing skeletal muscle levels of carnitine. Some resaerch suggests that you can make it work with very high dose insulin infusion, since this appears to increase uptake into the muscle. But it takes a lot.

I have seen the research suggesting it may impact on androgen receptor sensitivity.

As note, literally all of this is covered in excruciating detail in The Protein Book . All the supplements, all the research, all the rationale. I’m just covering the basics here.
