What is the best portable protein that's real food?

[Dwight Schrute]

Honestly though, whey is cheap, doesn't cause me gas or any sort of gastric issues, and we've yet to see any studies done on top level competitive athletes with an exhaustive analysis of a multitude of biological markers, besides just simple nitrogen retention.

There have been many. What are you looking for?

Plus it doens't really take a study on athletes to understand the breakdown and absortion of nutrients. Normal feeding patterns are the same regardless. THe only exception would be post workout in which there are numerous studies.

I've read the studies by lemon where they examine nitrogen retention and conclude 1.8g/kg is the optimal amount for an athlete (based on nitrogen retention data), and I've read the pre-post workout stuff by tipton.

Besides nitrogen retention, creatine kinase levels (post exercise), 3-methylhistidine levels, etc are also useful in examining recovery. Amino acids also serve as the substrate for many enzymes (and indeed are used to form the enzymes themselves) and increased protein intake could theoretically provide some benefit in this regard (much as coq10 and citrate provide some minor benefit to some people).

Tipton himself stated his results were inconclusive and even stated that you would have to follow his recommendations for 2 years to have any significant difference (pre post workout nutrition).

All those criteria listed can easily be found. Like I said, noraml feeding patterns and the hormonal response are almost identical. THe problem with some of those lsited above is they are measured in studies which amino's are administered intravensouly (most notably CK levels). Amino's act as protein catalysts for many function such as bone growth and the conversion of other amino's in glucsoe. These types of reactions happen with low-mod protein intake. There really is no need to increase protein level for those reasons.

Plus the more postive nitrogen retention is achieved the less protein gets utlized. There is a time when the threshold is reched and after that it either collects in the large intestine to be excreted, stored as fat or converted in glucose.

If you do the math, 1.8g/kg is not that high. For someone at 240 at 10%bf its only 97kg x 1.8g = 175g of protein.

The only reason I raise it higher is for the the thermic effect actually mean something. With the RDA recommendations, it doens't do mch at all.
