In a mere 30 minutes, Jasmuheen, winner of the 2000 Ig Nobel Prize for literature, explains as best she can how and why she does not eat. Jasmuheen was awarded the prize for her book “Living on Light,” which explains that although some people do eat food, they don’t ever really need to.
For the specialist: If you have the proper background, perhaps enhanced by a long-term scrupulous avoidance of food, you find more detail in a multi-part video lecture series by Jasmuheen.
