Why does it turn out that the hunger artist fasted only because he never found the food he liked?

The pleasure and artistry of fasting comes from the free will he exercises in his self-denial and masochism. Though he is confined to a cage, he has complete control over his pain and hunger (except when the impresario manages him), pushing himself past human limits in his constant search for a new masterpiece of starvation. Kafka romanticizes the hunger artist as an alienated "starving artist" who flouts capitalist society and concentrates solely on his own art from his virtual one-room apartment.
