Hunger Bar not depleting

Playing on Nintendo Switch, my hunger meter almost never depletes. I've tried toggling Natural Regeneration, switched between Normal and Hard modes, created new worlds, and the problem persists. I'm definitely always playing on Survival mode, and I've also tried switching my Personal Game Mode from Default to Survival. 

In game, I've tried taking damage from various sources, sprinting for long periods of time, and only very rarely does the hunger bar deplete. Occasionally, it will even refill itself when I'm not eating anything.
