Lee Halpin, 26, had planned to spend a week living on the streets in his home city of Newcastle to experience what it was like to be homeless.
He embarked upon his project on Sunday but he was apparently found dead three days later in a derelict building.
How he died has not yet been confirmed but due to the freezing temperatures it is believed he may have succumbed to hypothermia.
Speaking on a YouTube video, he said the project was part of an application for an investigative journalism course to give an example of fearless reporting.
He said he had spoken to a homeless charity about the rise in the number of people on the streets and the possible repercussions of the bedroom tax.
