That a gram of fat is roughly 9 calories? You seem to believe that at some amount of regular ingestion it will start getting processed differently? I'm not sure what kind of a paper you'd like, I don't think anyone will come up with specifically olive oil.

As per your other reply to the same link

  differing degrees of nutritional satisfaction per calorie ingested

Yes it's commonly thought to work that way, there are indeed differences - but they're tiny. I might try to dig up relevant papers, but as far as my memory goes, the difference was at best around 3% with certain kind of protein.
