stearic acid, in particular, is very important because it is a precursor for a hormone that signals satiety. this is why the carnivore people talk about it so much. i have several times experienced after eating about 600g a day for a couple of days, that for a whole day i don't feel hungry.

this fatty acid also is found in cacao butter, so you can get some of this without eating meat, though there is loads of other good things in the beef that help in other ways. stearic acid is a commonly used pill coating material, it's a hard waxy substance that gives chocolate its rigidity and brittleness.
