I mean yeah if we viewed starvation as some uncontrollable demonic force of the body then that would change things but would that be better or worse than the scientific approach? Maybe you have an example to better hit home the point you're getting at.
All forms or attempts of understanding reality aren't early science as in they weren't employing the scientific method in full but observation, testing, and measuring are basic aspects of being alive and aware. I know my nose is on my face through observation, testing, and measurement.
I'm aware reality can be strange, there's a plethora of epistemological arguments to show one the limits of science, but we're not talking about what lies beyond measure and testing or at least I'm not. There's lots of philosophical ideas about things we can not measure or test. Once again what does not appreciably effect reality measurably is worth awareness but not as much as what can be measured and directly influenced.
I wouldn't suggest one use science to attempt to understand epistemology but I would suggest it for methodically increasing societal wellbeing. The view one takes may change their behavior but it won't change physics. They can believe they can fly unassisted but will fall to their death all the same when leaping from a building.
