That's insane. I mean, they don't even taste all that good, but there's something about them that makes me have to eat more than one. Even when my body desires no food, it has no problem scarfing down Pringles. In fact, I've often eaten an entire industrial-sized can in one sitting, and wasn't any closer to being "full" than I was before I started.
The same thing happens to me with Flamin' Hot Cheetos (which I have long-since quit by now, but I frequently miss them), but that's because I love how they taste; it isn't an unexplained phenomenon like it is with these fake chips.
So who else gets this effect, and with what snacks?
