British doctor Michael Mosley who popularized the 5:2 diet goes missing on Greek island

CNN - British journalist, writer and doctor Michael Mosley, who popularized a type of intermittent fasting known as the 5:2 diet, has gone missing on the Greek island of Symi.

A search operation is underway after his wife reported him missing on Thursday morning, Reuters reported, citing local police officials. His agent has also confirmed his disappearance to PA Media.

The television doctor – known for UK documentary shows such as Channel 4’s “Michael Mosley: Who Made Britain Fat?” and the BBC’s “Trust Me, I’m A Doctor” – was last seen early afternoon local time on Wednesday heading out for a walk.

The 67-year-old broadcaster has also appeared on British factual entertainment programmers such as BBC’s “The One Show” and ITV’s “This Morning,” and has been a columnist for British newspaper the Daily Mail.
