According to DC Comics lore, Superman's cells act like a living solar battery, constantly absorbing energy from a yellow sun. Given this, the question of how many calories does Superman need is fundamentally flawed, as his metabolism operates on a completely different principle than that of a human.

While a typical human relies on food for sustenance and energy, a Kryptonian under a yellow sun has no such biological requirement. The question, 'Does Superman eat regular food?', has a complex answer rooted in his alien physiology, his human upbringing, and a desire to connect with humanity.

In most portrayals, Superman possesses unlimited stamina, sustained by the radiation of a yellow sun. This fundamental biological trait provides a definitive answer to whether a Kryptonian superhero like Superman needs food and sleep for survival, though his actions suggest a more complex psychological need.
