The purpose of Hunger Strike Mod 1.8, 1.7.10, 1.7.2 is to dial back the hunger system for players that wish to play in a Survival world without having to constantly feed themselves. This mod is designed to be configurable on a per-player basis for SMP servers, so not all players need to be forced one way or the other. This will tilt balance, but whether that is acceptable is up to you.
