I don't know any specific research on this.  The way in which
caloric restriction slows aging appears to be by slowing all
metabolic processes (muscle mass is lost, body temperature goes
down, etc.).  Protein, on the other hand, has a thermic effect
that in effect increases metabolism.  So it makes sense that it
would shorten life somewhat, if the rest of the assumptions about
aging are correct.
