An initial post-mortem of British TV doctor Michael Mosley’s body has found he likely died of natural causes.

The TV presenter’s body was found in a rocky area on the Greek island of Symi on Sunday, four days after the 67-year-old went missing after setting off for a walk.

According to the BBC, Greek police said an initial post-mortem of Mosley’s body found no injuries that could have caused his death — or that it was a criminal act.

“It has emerged there are no injuries that can be linked to a criminal act,” reported Greece’s public broadcaster ERT.

They said his time of death was around 4pm on Wednesday (local time), which was the day he went missing.

The post mortem reflected a consensus among Greek officials that Mosley died of exhaustion after taking a wrong turn on his walk, The Guardian reports.

The day he went for his walk, the local temperature exceeded 37C, which prompted an alert by Greece’s meteorological service.

Mosley’s wife, Clare Bailey Mosley, said her husband took the wrong route on a hike and collapsed just short of reaching a marina in a place where his body couldn’t easily be seen.

“Michael was an adventurous man. It’s part of what made him so special,” she said in a statement.

“It’s devastating to have lost Michael, my wonderful, funny, kind and brilliant husband. We had an incredibly lucky life together. We loved each other very much and were so happy together.”

The body of British TV presenter Michael Mosley is carried from the spot where he was found.

Mosley is well-known in many parts of the world for his 2013 book The Fast Diet, which he co-authored with journalist Mimi Spencer.

The 5:2 diet, as it became known, set out how people can lose weight fast by minimising their calorie intake for two days a week while eating healthily on the other five.

Mosley is also known for his regular appearances on British television as well as his column in the Daily Mail newspaper.

He has also made a number of films about diet and exercise.

In 2002, Mosley was nominated for an Emmy for his executive producer role on the BBC science documentary The Human Face.

Mosley has four children with his wife, who is also a doctor, author and health columnist.
