According to scientific analysis, a human running at bullet speed would require an internal nuclear reactor just to generate enough energy, which is why the question 'do speedsters need to eat a lot' isn't just a comic book trope, but a biological necessity for their superhuman feats.

This staggering figure only scratches the surface of the complex question: how many calories does the Flash need a day, which varies dramatically depending on the interpretation and source material.
