I want to change what affects the Hunger bar to be more Beta like

I want Hunger to behave more like Beta Minecraft, back when you basically never needed to eat/heal if you played well enough, with the downside of no sprinting.
These days you get hungry just by breaking blocks or swimming or even attacking mobs, which sucks.
I would like to remove exhaustion from everything besides sprinting, and regenerating (and the Hunger status obviously)
Is that even possible?
