The Ukrainian model holds up a Barbie doll, the inspiration for her look.A Ukrainian model who lives her life as a "human Barbie" hopes to become a "Breatharian" who survives off nothing but light and air.Valeria Lukyanova reportedly stopped eating and drinking water and claims to solely subsisting off "cosmic micro-food.""In recent weeks I have not been hungry at all; I'm hoping it's the final stage before I can subsist on air and light alone," she told IBT.The young woman first made headlines in 2012 when she underwent radical plastic surgery to transform herself into a living version of the popular doll.At the time, she said she wanted to be "the most perfect woman on the Internet."Many critics questioned whether she existed at all, asking if the images in circulation were just extremely Photoshopped versions of herself.In the following 24 months, however, several media outlets report to have conducted face-to-face interviews with the impossibly thin-waisted woman.But she is now facing further criticism for her conversion to "Breatharianism" — labelled a potentially lethal pseudoscience from which several partakers have reportedly starved to death.It's not the first time Lukyanova, who works in new age opera and is supported by her construction-working husband, has said something weird.Claiming she is from another planet, she's previously said she can speak to aliens through light and perform time travel.(nydailynews.com)ANN.Az
