how do we do a command that makes it so we lose hunger faster in minecraft forever [closed]

Run a command block which grants you the Hunger effect for 60 seconds, and put it on a timer that repeats every 50 seconds.

The command would be /effect @a minecraft:hunger 60 1 true; the timer could be redstone or command block based. To make sure it is a constantly loaded chunk, /forceload it (syntax here).
