First, let’s talk about energy... on a cellular level. Your computer runs on electricity, your car runs on gas and your cells (therefore your body) run on ATP. Much like the other fuel sources, ATP needs to be processed and is consumed. But instead of one power plant producing enough electricity to power millions of computers, your body is equipped with a power plant in each cell to produce ATP. Yep, we have trillions of little power plants using the calories we eat to produce the ATP we need.
