Satiety

 is a measure of how full you are from eating. Between your Health and Stamina bars to the right of your portrait in the upper left corner are the satiety bars, one for each of the 5 food types: Meat, Bread, Vegetables, Fruit, and Mixed.

Satiety is reduced to restore Stamina, so if you aren't using stamina, satiety won't decrease. The rate at which stamina is restored increases with each satiety bar that is >0%, so eating a variety of food types will provide better stamina recovery.

is increased by eating Food. The satiety bar that increases is determined by the food's Hunger type and the amount of the increase by its Hunger value. When the satiety bar for a given food type reaches 100%, you will be unable to eat any more of that type of food until it drops below 100.

If all of the satiety bars drop to 0, you will start to experience and your stamina will no longer be restored. If you don't eat, this will turn into, you will be unable to run and will gradually lose Health. If your health reaches 0, you will die!
