Minecraft wiki entry for Hunger, associated text: As a visible sign that the saturation is used up, the hunger bar starts to shake or jitter periodically. When the saturation level is at zero, once the exhaustion value reaches 4, the total hunger value is decreased by one hunger point. Eating food replenishes both hunger and saturation levels (see Food level and saturation level restoration for specific values), with the hunger level being replenished first, which also increases the maximum allowed saturation level. For example, if a golden carrot (giving 6 () and 14.4 saturation points) is eaten by a player whose hunger bar is at 9 () and saturation is below 1, its value increases to 15 (), and the golden carrot's saturation potential is fully used. However, if the hunger level is 8 (), its value increases to 14 () and only 14 saturation points are used.
