With steak there's the confounder of cooking. I ate a steak very nearly raw once, couldn't finish it. My friend fried it in butter, and the first bite returned my appetite. Still couldn't finish it, it was a big steak. He fried it again, appetite returned again, even though I like steak very much just raw when I'm hungry, as hunger decreases, cooking seems to trigger my appetite. Advanced glycation end products taste pretty good. Maybe that's a factor in scrambled eggs as well?
