If I understand you correctly, you are implying that the more recent paper in someway contradicts or undermines the earlier one. I don't think this is the case. The more recent paper is about the distribution of protein intake throughout the day, not the presence or absence of protein in one's diet. The only claim of the recent paper is that it makes no difference what time of day you choose to consume your protein. It is not comparing a diet with protein to one without protein.
