What is the World’s Lowest Calorie Food?

The lowest calorie food in the world is a Japanese group called Konnyaku or Konjac. A 100gram serving of Konnyaku has 6 calories. To make this even better, Konnyaku are very filling because they are extremely high in dietary non-digestible fiber and so they keep you full for a very long time making the perfect diet food. Konnyaku usually comes in either a jellylike block or in the form of noodles.
