I believe the "magic" of feeling full is the fact that the coconut oil is highly saturated, the olive oil is mono-unsaturated. I don't really have anything to back that up...just something I've noticed. Must be something about how my body handles the 2 fats.

I don't get any satiety whatsoever from olive oil--in fact I get hungry again quickly after eating it as my main source of fat in a meal. The same amount of fat as a saturated fat (butter, cream, lard) will hold me for hours.
