Just ran across this article today: Why some continue to eat when full. It basically describes how ghrelin, a hormone connected to eating and appetite, works to keep us eating.
Scientists previously have linked increased levels of ghrelin to intensifying the rewarding or pleasurable feelings one gets from cocaine or alcohol. Dr. Zigman said his team speculated that ghrelin might also increase specific rewarding aspects of eating.
Are we helpless in the face of all this biology working against us? No, we should be able to outwit Mr. Lizard Brain, as I discussed in that posting.
Dr. Mario Perello, postdoctoral researcher in internal medicine and lead author of the current study, said the idea was to determine "why someone who is stuffed from lunch still eats -- and wants to eat -- that high-calorie dessert."
Any over-eater worth their salt already knew about the "dessert box". That's the portion of your stomach that never gets full when presented with delicious things you want to eat. Dinner food is great and all, but I can get full on meat and veggies and not want to eat more. However, the "dessert box" is always empty (or almost always).
