A 58-year-old man named "Gholamreza Ardeshiri" claims that he has been surviving on water and carbonated beverages like Pepsi and Coca-Cola for the past 17 years, as the mere sight of food makes him feel nauseous.

He began in 2006 when he woke up with a strange sensation in his mouth, a feeling he could not get rid of. He says: "I had a strange feeling, I felt like there was something like hair inside my mouth, I felt that the head of this hair was inside my mouth and the end was inside my stomach, no matter what I did, it was impossible to remove this hair."

Ultimately, he decided to permanently avoid food and has been living a completely normal life since then. His family does not eat in front of him, as the mere sight of them makes him sick, and he gets all his energy from carbonated drinks, drinking up to three large bottles of soda daily, and insists that he never feels hungry.

He has visited many doctors, but no one has been able to diagnose his condition. There was no hair in his mouth, and others have advised him to visit a psychiatrist, but the issue has not been resolved, so he has decided to completely give up on food and live on soda.
