Dr Michael Mosley has gone missing on a Greek island, according to reports.
The 67-year-old is known for appearing on television programmes like This Morning and The One Show. He also hosts the Just One Thing health podcast for the BBC.
He is also credited for the rising popularity of the 5:2 diet for losing weight, which involves fasting for two days per week.
An appeal has been shared in a local Facebook group after his disappearance on the island of Symi.
Symi is part of the Dodecanese island group and had a population of 2,590 in 2011.
The appeal read: "A search and rescue team is coming from Athens with drones and other more sophisticated equipment to extend the search.
"They are expected to arrive by about 1 p.m."
The post, which included a picture of the medic, added: "Have you seen this man? He set off to walk back from St Nick's at about 13.30 and failed to make it home. His friends are concerned as it is 6 hours since they last saw him.
"His name is Dr Mike Mosley and he is a familiar face for many British people."
One user on a local forum said Dr Mosley "left his phone at his accommodation".
"These days it should be pretty difficult to get lost on Symi as so many of the paths have been surfaced and there is a lot more activity even in the most remote areas," they added.
