A single gallon of gasoline contains approximately 31,000 food calories (kcal), a staggering amount of potential energy released through combustion, not digestion. This raises a common, yet dangerous, question: how many calories does gasoline have and why can't we use it as fuel for our bodies?.

While a gallon of gasoline contains an astonishing amount of chemical energy—around 31,000 food Calories—it is extremely toxic to humans. The existence of calories in gasoline does not make it a viable, or safe, energy source for the human body. This stark difference highlights the critical distinction between raw chemical energy and biologically usable energy for metabolism.
