If you like weird sounding and exotic foods, then maybe you should try the konnyaku. This Japanese product is a low-calorie food that came from a plant called konnayku from the taro family. This is as close to as zero-calorie as you can find.

This is actually a gelatinous block of water that is solidified by the addition of pulverized konnyaku powder and sometimes seaweed powder. One package of konnyaku range from zero to 10 calories, depending on how it is made. If you eat konnyaku in one day, you’ll have the experience of feeling full but still slightly hungry at the same time.

Although Konnyaku is basically devoid of taste, it is still rather delicious when you incorporate it with other food products. It has a delightful, bouncy texture that can be made into soup or fish dishes.
