                                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.
