Feeling sated can become a cue to eat more

http://ift.tt/eA8V8J When hunger pangs strike, we usually interpret them as a cue to reach for a snack; when we start to feel full, we take it as a sign that we should stop eating. But new research shows that these associations can be learned the other way around, such that satiety becomes a cue to eat more, not less. The findings suggest that internal, physical states themselves can serve as contexts that cue specific learned behaviors.
