Hunger is a derived statistic in Fallout 4's Survival mode, Fallout 76, and Fallout: The Roleplaying Game.

Fallout 4

Characteristics

Hunger occurs if the Sole Survivor does not eat food after a long enough period of time. It accumulates slowly at all times. Increased levels modify SPECIAL stats. Higher hunger levels induces Fatigue, at which Action Points will become affected. Ultimately, damage will be taken, reducing Hit Points. Most types of food will reduce hunger by some amount, though certain foods are more effective than others.

Stages of hunger

There are 6 stages of hunger that span in-game hours. It doesn't appear that the thresholds are linear. For example, it takes about 6 hours to go from well-fed to peckish to hungry, then 12 hours to go from hungry to famished. The following table shows the approximate times that it takes for a character to go from completely satisfied to the listed condition in each area. In-game time is expressed in "hours" and real-time is expressed in "minutes." Starving is not lethal, Hit Points will only be lost from its "Periodic damage" effect while the affected actor has over 20 Hit Points.

The In-game / real-time data in this table are approximations only. The time expressed is not truly accurate. This table may be incomplete.

Fallout 76

Hunger is determined by how much the Vault Dwellers have eaten. Originally, hunger could cause both buffs and debuffs, but as of the current version it only grants bonuses and doesn't give penalties.

Fallout: The Roleplaying Game

Hunger is a survival statistic that must be tended to by ingesting sustenance wherever it can be found. All character origins (with the exception of Robots) must feed themselves or risk increasing their hunger states and incurring fatigue points.

Eating a food item moves back the state of hunger. Eating uncooked food and preserved pre-War food moves the character back up one step (i.e., from hungry to peckish), while prepared food moves the character back up two steps instead (i.e., from peckish to full).

If starving, hunger is a source of fatigue.
