Honestly, from what I've seen and experienced, aside from the prevalent commonality of carb consumption begetting more and more carb consumption (which could have been a factor with your pumpkin cheesecake, since it surely was made with real sugar), we all have different "trigger foods".

I may eat cheese every single day, but while cheese may trigger binge behavior in some people, it doesn't trigger the all-or-nothing, "one bite is too much, the entire block is never enough" reaction for me. I have some cheese on an omelet for breakfast, maybe some in a dinner recipe, and sometimes a few "cracker cuts" slices makes a good snack (when they give me a break so early at work that it's way it's too early for a real meal, or even a filling snack, but feel like I'd better eat something, or else I know I'll be really hungry before they ever manage to give me another break). I enjoy the cheese, but it doesn't trigger me to eat more and more cheese.

For me, it's nuts (tree nuts, since I don't even like peanuts) that most often evokes the all-or-nothing kind of reaction. I haven't had sugar/starch in quite a while (so long that it tastes awful to me now), but based on my previous decades as a completely out of control high carber, if I ever got used to the taste of sugars and starches again, I can guarantee you those two general categories would start me on an all-out binge again. I don't have that problem when I sweeten LC goodies with stevia. They may taste plenty sweet to me, but the stevia is a different flavor, and doesn't trigger a craving for more sweets, much less sugary sweets. Come to think of it, when I've used sucralose, or saccharin, I don't get that problem either.

My point is that everyone is different, just like Teaser's story with the meat - nearly raw, he reached a limit. Then fried in butter he ate more until he reached another limit. And then cooked some more, he finally reached his final limit because it was all gone.
