Unnatural Hunger
From ATLauncher Wiki
Unnatural Hunger is an effect added by the Thaumcraft 4 mod.
It acts like Hunger except while it is active, eating normal food will give almost no hunger restoration and saturation points. The only option to remove this effect is to eat Rotten Flesh, which removes 60 seconds of active effect, or eat Zombie Brain, which removes first 40 seconds and second will remove all active effect. Eating brains will give the player temporary Warp though. This effect also gives reddish shader effect while it is active.
Can be obtained by player as a Warp event.
