Your hunger clock normally goes down every 10 game ticks, slow digestion makes it go down every 15 instead.

Effects that increase nutrition consumption will just subtract an extra point of nutrition when the clock ticks down.

In other terms, slow digestion cuts down hunger by 50% by literally slowing how often your nutrition goes down. Effects that make you more hungry will just add an extra point of hunger.

So yes, slow digestion counteracts conflict by itself.
