FullBelly
by 110011100101
With FullBelly installed, each action a player takes on a NeoForge 1.21.1 server uses up food, so survival hunger follows what the player does.
What it does
FullBelly tracks 26 types of player behavior and deducts hunger for each one it records, so movement and other actions consume food and make eating a more regular part of play. The deduction is built on the vanilla exhaustion mechanism and stays compatible with native game mechanics. The mod ships an optional debug mode that lets a player watch the values change as they act.
Calculations run on the server, so the mod adds little load on the client. It is server-side only, which means players join without installing it and only the server needs it. Files are published for NeoForge 1.21.1, with 1.0.3 as the latest file from 2026-05-16, and the mod is released under the MIT License but is not open source.
Key features
Action-based hunger
Movement and other tracked actions consume hunger, so food becomes a resource that gets spent during play.
Full action coverage
The mod tracks 26 player behaviors and applies a matching hunger cost to each of them.
Debug HUD overlay
When debug mode is on, a HUD overlay shows food level from 0 to 20, exhaustion as a percentage from 0 to 100, and the last five actions.
Total exhaustion counter
The overlay adds up the exhaustion caused since debug mode was enabled, so a player can see the running total.
Combo detection
Actions that fall close together in time and belong to one group are bundled, and the newest bundle is marked with a green background and emoji icons.
Toggle through commands
Debug mode can be switched on and off with in-game commands or a configuration file.

Use cases
Who it’s for: FullBelly suits server owners running NeoForge 1.21.1 who want survival hunger tied to what players do. Players only need to join the server, since the mod is server-side only.
