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.

According to Marvel comics lore, the Hulk’s very existence is powered by high-energy gamma radiation, meaning traditional calorie counting does not apply. The question of 'how many calories are in the Hulk?' is a fascinating blend of superhero fiction and real-world science, requiring us to consider both his extraordinary energy source and immense physical form.

According to established DC Comics lore, the cells of a Kryptonian under a yellow sun function like living solar batteries, absorbing and converting solar radiation directly into energy. This unique physiology is central to the question: do Kryptonians need to eat food, or is their famous strength merely a side effect of their solar-powered existence?

While the query sounds like a superhero-related riddle, a flash of light, even one intense enough to cause a medical 'flash burn' like from welding, does not burn calories in the human body. Calories are units of energy from food, metabolized by the body for biological processes, not consumed by external light exposure.
