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.

According to one source, Quicksilver's body is so efficient that it metabolizes 95% of ingested food for energy, compared to a human's 25%. But to power his super-speed feats, how many calories does Quicksilver need to eat on a daily basis? The energy requirements vary drastically depending on whether we use comic book logic or real-world physics.

In Marvel Comics, the Asgardian diet is a complex subject, with one thing remaining constant across most storylines: while Thor and his kin enjoy feasting, they do not require mortal food for survival. This incredible ability to survive without sustenance is a cornerstone of his godly physiology, setting him apart from human heroes.

According to one fan calculation, the calmer 'Smart Hulk' would still need an estimated 17,160 calories daily just to maintain his immense mass, highlighting the extraordinary scale of metabolism required by the incredible Hulk.
