IF there is no hunger or thirst bar in the game then what to reason order pizza or eating food?

I readed then game comes out in late 2017 or early 2018, but can u play this game before release date?

Im sorry if i dont have good english or founded Seach bar but if u answer my question u can help those people who look this topic to find out when game releases. Those 100 viewers is looking for a date when this game release not whining about search bar. Thank you.
