Jasmuheen (born Ellen Greve; 1957) is a proponent of "pranic nourishment" or breatharianism, the practice of claiming to live without food or fluid of any sort and regarded by the scientific community as a lethal pseudoscience.

[1] She makes appearances at New Age conferences worldwide, has hosted spiritual retreats in Thailand and has released books and audio recordings.

In 1992, she began combining her experience in business and finance with meditation, selling access to workshops and seminars on the topic and, by deed poll, changed her name to Jasmuheen.

The supervising medical professional Dr. Beres Wenck found that, after 48 hours, Jasmuheen displayed symptoms of acute dehydration, stress, and high blood pressure.

On the third day, she was moved to a mountainside retreat about 15 miles from the city, where she was filmed enjoying the fresh air, claiming she could now successfully practice inedia.

In the aftermath of the 60 Minutes broadcast, Kathy Marks noted in The Independent, "Visitors to her large villa in the prosperous Chapel Hill area of Brisbane invariably find her refrigerator generously stocked with food, all of it destined, she insists, for the stomach of her second husband, Jeff Ferguson, a convicted fraudster".

[5] Jasmuheen has stated that she has lived on approximately 300 calories per day for the past fourteen years, maintaining full health through supplementing a fluid intake with "cosmic particles" or "micro-food", which she describes as prana.

[6] She was also awarded the 2000 Ig Nobel Prize for Literature for her book Pranic Nourishment – Living on Light, "which explains that although some people do eat food, they don't ever really need to.

[14][15] In 2012, it was reported that a Swiss woman died of starvation after having attempted to survive purely on light, as taught in one of Jasmuheen's books.

According to witnesses, he was not eating or drinking for several days ahead of his death, and had told friends and family members of his plans to only live off of sunlight.
