Appetite, the inherent desire to eat, is a biological and psychological phenomenon that regulates energy intake through intricate interactions between the body and mind. From Brillat-Savarin’s poetic portrayal of appetite as a prelude to the pleasure of eating to Stevenson’s critique of emotional hunger eclipsing physical needs, writers have long examined its dual nature as both a bodily impulse and a metaphor for yearning.
Eugène Sue contrasts the temporary joys of indulgence with profound existential despair, while Macé associates appetite with intellectual curiosity. These viewpoints highlight appetite as a lens through which human behavior, ranging from sustenance to neurosis, is reflected.
