Do you have any idea how unreliable hunger and thirst are when it comes to your body's actual needs? Just look at the vast amounts of obese people eating whenever they're hungry.
It's not a status bar, it's just a feeling. It has purpose and it's useful but it's not some sort of magical measuring device that monitors your body's need for nourishment. Simply eating the exact same quantities of food irregularly will cause it to go off, even though your body is getting enough to sustain itself.
All hunger is is the release of hormones, causing contractions in your stomach muscles. Hormones that are many times released when they're needed and often enough at times when they're not really needed, more of a first world problem though.
Those hormones and similar structures are at the basis of our psychology. Not the resulting feeling of hunger. And understanding that is vital to a healthy lifestyle. Understanding that feelings of hunger, thirst, lust, tiredness, fear etc. are simply that, feelings. They're simply warning signs of our body that something is going on, the result of incredibly complex interactions that occur in our nervous systems and bodies. They are not the building blocks of our psychology, they are merely the resulting awareness of it.
