I have a few concerns, or questions in regards to why you posted this study?
1) This study did not prove that egg whites are not beneficial. In fact, plasma leucine was more rapid after egg whites than the whole egg, which can be used to one's advantage. After 300 minutes they were the same, with no benefit to either group. It lists that both have beneficial effects, but the whole egg resulted in greater stimulation of myofibrilar protein synthesis post-w/o.
-It shows an advantage of WE's over EW's, but it does not show that egg whites are worthless. One is better than the other in a certain aspect, but you also have to factor in that this was an acute study where calories are measured over a short period of time, which ultimately muscle protein synthesis over an "anabolic window," does not matter when you account for the whole day's worth of calories. this study is kind of misleading in that it did not account for the overall calorie advantage when comparing WE to EW. When they are matched over a whole day, it is moot.
2) The study you cited was a precursor to the study here below, why not post it instead?:

Abstract
Eggs are considered a high-quality protein source for their complete amino acid profile and digestibility. Therefore, this study aimed to compare the effects of whole egg (WE) v. egg white (EW) ingestion during 12 weeks of resistance training (RT) on the skeletal muscle regulatory markers and body composition in resistance-trained men. Thirty resistance-trained men (mean age 24·6 (sd 2·7) years) were randomly assigned into the WE + RT (WER, n 15) or EW + RT (EWR, n 15) group. The WER group ingested three WE, while the EWR group ingested an isonitrogenous quantity of six EW per d immediately after the RT session. Serum concentrations of regulatory markers and body composition were measured at baseline and after 12 weeks. Significant main effects of time were observed for body weight (WER 1·7, EWR 1·8 kg), skeletal muscle mass (WER 2·9, EWR 2·7 kg), fibroblast growth factor-2 (WER 116·1, EWR 83·2 pg/ml) and follistatin (WER 0·05, EWR 0·04 ng/ml), which significantly increased (P < 0·05), and for fat mass (WER -1·9, EWR -1·1 kg), transforming growth factor-β1 (WER -0·5, EWR -0·1 ng/ml), activin A (WER -6·2, EWR -4·5 pg/ml) and myostatin (WER -0·1, EWR -0·06 ng/ml), which significantly decreased (P < 0·05) in both WER and EWR groups.
The consumption of eggs absent of yolk during chronic RT resulted in similar body composition and functional outcomes as WE of equal protein value. EW or WE may be used interchangeably for the dietary support of RT-induced muscular hypertrophy when protein intake is maintained.
The study above has weaknesses as well, but it is a f/u study to the one you posted.
I think people who are saying "eat the whole egg" are taking his question out of context, which had nothing to do with eating a whole egg, but rather eating eggs out of the carton, which was the topic at hand. Yes, eating a whole egg can be beneficial in the context of the person's diet and how it is structured, but it may not be also, depending...on the context and how their diet is structured. Not everybody wants the added fats in their diet like others do, so again, the context of adding more egg whites can be beneficial for them.
BTW...not knocking whole eggs, or you Emeric, I have a lot of respect for knowledge that you bring. Thanks!
