If I was really seeking serious proof that you were hungry, I could certainly
find an objective way of verifying it.  Of course, it would take a lot of
data.  It would take an analysis of the current state of your digestive system,
knowledge of how long it's been since you last ate (sometimes the brain simply
wants food as a sensation experience without actually being hungry), and
data on the break points at which your body sends messages that your require
food.  I doubt we have the capabilities to gather all of that (if we did,
it might be at the expense of your life, anyway).  Do you have a better example
of this?  (Fact is, sometimes the problem with obese people is that they
feel "hungry" without chemical motivation for that feeling, and thus eat too
much.)

By definition, you are saying, it is only to be called knowledge if it is
certain to be true.  At bottom level, true knowledge IS self-evident,
representing a consistently accurate model of the world.  Subjective beliefs,
very often, do not stand up to that scrutiny, and are not "self-evident"
at bottom level, but rather self-contradictory.

Not at all.  If you get to the bottom level, they are verified in exactly
the same way.  Often, we choose not to go to the root level, and assume
the veracity of certain things, owing to the tediousness of a redundancy
we feel is not worthwhile in every case.  That of course leaves us very
open to being out and out wrong.
