If only 58% of proteins (on average, according to a study) are converted to glucose, due to the fact not ALL amino acids can be convered via gluconeogesis....does that mean the 42% left does not count toward calories?
so basically a protein would only be worth about 2 calories considering not all amino acids can be converted to glucose?

I'm not famaliar with the study you're referring to, but from what I understand, all proteins are converted to Amino Acids. If there is an excess of protein then the excess amino acids are then converted into glucose or keytones.
Protein is not initially converted to glucose but only in excess so that study you are talking about must have been based on certain intake of protein and one persons body and what they found was that person converted 58% of it to glucose for fuel while the other 42% was converted and retained as amino acids....
I would like to see the study myself though... do you have a link??

Either way... the 4 kcal for 1 gram of protein would still stand.

Huh??????

gluconeogesis converts amino acids to glucose. right?
basically, 1 gram of pure amino acids would convert to 1 gram of pure glucose, thus be worth 4 calories. right?
however, only a fraction of the amino acids can be converted to glucose. according to a study (ill be looking for it) it seems to be 58% of diet amino acids. so basically the 42% amino acids left are unable to be converted via gluconeogesis.
so that would mean that 1 gram of protein/amino acids would only yield 0.58 grams of glucose, and thus be only worth about 2.3 calories.
is my math right?

The other 42% remain as protein... which has a calorific value.... The body must still metabolise this protein
Just because it is not used as energy does not mean it has no calorific value....
VET
Or maybe the study was referencing that gluconeogesis is a very caloric costly way for your body to create energy and 42% of the amino acids are used up in the conversion process?

Okay.... from my understanding, Protein is not converted to glucose, unless there is a surplus... this is what I have always known to be true.... am I completely wrong and retarded?? Cuz thats been known to happen

Read into Glucogenesis...Okay.... from my understanding, Protein is not converted to glucose, unless there is a surplus... this is what I have always known to be true.... am I completely wrong and retarded?? Cuz thats been known to happen

Protein isn't necessarily converted to glucose when there's an abundance of it but rather when the bodies' energy requirements can't be met by the other much preferred energy sources (glucose and fatty acids).Okay.... from my understanding, Protein is not converted to glucose, unless there is a surplus... this is what I have always known to be true.... am I completely wrong and retarded?? Cuz thats been known to happen

Thank you....
After reading up on Glucogenesis and reading what you said Sarge, it all makes a little more sense to me.... I learned something new today....
