How do we even know it is true for you? Given that a self-evident proposition is one that is known to be true just by understanding its meaning, without the need for proof, why do you think that you claiming you do not feel hungry is self-evident when we can not possibly know the truth of it? Because you say so? You might know the truth of it, but actually you would do so through your emotions, which provide you with the proof of your claim (and no doubt the cause of). (As such it is questionable whether even you can claim "I do not feel hungry" self-evident.) We certainly won't know the truth of it, unless we subject you to testing, if such testing exists. So how can we know whether you are hungry or not just from you saying so, and thus accept that it is self-evident? As said, even with what is held by some as the only self-evident claim ("I am conscious") is only self-evident for the one making the claim, not for anyone else. You think something needs to be falsifiable, or even actually falsified, for it not to be considered self-evident? What a bizarre notion.
