According to the CW's 'The Flash' TV show, speedster Barry Allen once told friends he needed to consume around 10,000 calories per day just to function. This immense dietary requirement raises a compelling question: why does Barry need to eat so much to maintain his superhuman speed? The answer lies in the complex and demanding physiology of a speedster, where every burst of speed burns through energy at an unsustainable rate for a normal human body.

Peter Parker, due to his enhanced metabolism, requires an exceptionally high number of calories, often consuming large amounts of food. This has led many fans to question his specific dietary needs, including the popular fan theory asking, "Is Peter Parker lactose intolerant?".

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.

According to DC Comics lore, Superman's Kryptonian cells are living solar batteries, constantly absorbing and metabolizing solar radiation from Earth's yellow sun. This unique physiology provides him with all the energy and sustenance he needs, meaning he technically does not get hungry in the human sense.
