"How do you explain that someone with more fat needs more protein? Does fat somehow increase the protein requirements?"
Nitrogen metabolism/loss is claimed to be directly related to body weight (including bone, too!). Nitrogen balance is how the lab rats measure protein requirement.
I note that Enrico's suggestion of 1g/kg-day is high compared to the current North American RDI of 0.8, and the Mediterranean diet was supposed to be low protein then ...
"Turned out the average weight of his Italian passengers was 240 lb, and Canadian regs assumed 160!"
In fairness to Italians, I should note that his passengers' luggage was full of presents and that they turned out to be wearing everything that didn't fit within the luggage weight limitation. But let me tell you, you abort takeoff with a hundred people sitting on your shoulders and you don't forget it!

Well, I was just guessing. Consider that it was mostly vegetal protein, from legumes, wheat and so on.

But you said it was a flight from Toronto to Italy... so they must have overeaten in Canada! :-D [just kidding!]
