Didn't want to ask but the new Xtend...

[mminguela]

There has been heated debates over the past few years about the calorie count of the old Xtend. I believe it was determined that one scoop = 20 calories. So the new version = 40 calories? Since 2 scoops of the old is equal to 1 scoop of the new version.

1g of BCAA's = 1g of Protein
Therefore 1 serving = 7g of BCAA's = 7g of protein.
2.5g Glutamine = 2.5g Protein
9.5g Protein x 4 ~ 40 calories.
(Most of Layne's / Tommy's Clients count 10g of protein per 1 serving Xtend)

Ok thanks. Still counting it as 1 G protein even though it's incomplete?

[in10city]

Leucine: ~5.9 kcal/g
Isoleucine: ~5.9 kcal/g
Valine: ~5.2 kcal/g
Glutamine: ~3 kcal/g

In isolation, individual amino acids have different heats of combustion and resultant metabolizable energy. 4 kcal/g is an underestimation since it's based on the heat of combustion of a complete protein - which basically ends up being approximately a weighted summation of the heats of combustion of all 20 or so amino acids in the protein. Splitting hairs perhaps but incorrect on technical grounds.

Ya, I don't get this. If protein is made up of several amino acids, how on earth will 1g of an individual amino acid be equal to 1 g of complete protein? Surely Arginine and Glutamine and Leucine all differ in terms of how they interact with your body. Isn't this what MusclePharm or someone did with their protein gel product? Using a protein gel and counting it towards their total protein, when in fact, it is an incomplete protein, and as thus, shouldn't be regarded as a full protein source?
