Hunger Bar Won't Go Down

I am playing on the Xbox One and just downloaded the new version with the Better Together installation. I'm playing alone, started the game in survival, normal mode. The hunger bar isn't going down. Is there something else that could cause this now? Is anyone else having this issue? It was working fine this afternoon on another world.

Solution 1:

There is a hidden meter called saturation which has to empty before hunger starts going down. It's refilled by eating, though by how much depends on the food and is not related to how much hunger it fills. Pro tip: golden food is the best in terms of saturation.
