Have you ever noticed that some foods keep you feeling full longer while others give you the munchies an hour later? That can make the advice to "stop eating when you feel full" a bit tricky if you're picking foods that aren't filling. That's a phenomenon called satiety. It's the feeling of fullness, of being satisfied and satiated. It's is the opposite of hunger and appetite.

The satiety index is a rating of foods that have been tested for the satiating effect in a 240 calorie (1,000 kJ) portion size. The scale scores foods based on whether people feel extremely hungry, hungry, semi-hungry, no feeling, semi-satisfied, satisfied, or extremely satisfied.
