Swiss newspaper Tages-Anzeiger reports that a woman starved to death after embarking on a spiritual diet that required her to stop eating or drinking and live off sunlight alone.
The Zurich newspaper reported on Wednesday that the unnamed Swiss woman in her fifties decided to follow the radical fast in 2010 after viewing an Austrian documentary about an Indian guru who claims to have lived this way for 70 years.
Tages-Anzeiger says there have been similar cases of self-starvation in Germany, Britain and Australia.
The prosecutors' office in the Swiss canton (state) of Aargau confirmed Wednesday that the woman died in January 2011 in the town of Wolfhalden in eastern Switzerland.
Spokesperson Jennifer Rissi says prosecutors haven't opened a criminal investigation over the woman's death.
