I had stubbornly kept going with the "eat filler foods" method I'd used for almost three years before I realized that the new Satiation system had grind my food efficiency to halt. Apparently "Meat" also modifies sausages which means I practically there's no sense for me to eat them at my current situation.
To make things worse, UI is either bad or at least un-intuitive when it comes to telling what your efficiency with the food you're about to eat will be.
There's possibility that somehow custom client I sue doesn't render some UI element that would display this but there's a problem: default client doesn't start for me. At all.
