The zombies we call “Fatty Bursters” were people struck with potent diseases in their former life. Illness caused a weird change in the zombie plague, turning them into bloated, infected corpses. More than their horrendous complexion, their most surprising feature is unexpected bursts of speed. Certainly haunted by former memories, they rush all of a sudden to avoid an invisible and inescapable fate. And when Bursters are close enough, they simply stop trying to keep their corpses together and disintegrate in an explosion of gas, gore, and pus. No one wants to die like that!
