A police spokesman, speaking on condition of anonymity today (tonight AEST) because of an ongoing investigation, said the body was found on a rocky shore by a private boat and that official identification was pending.
The British TV presenter disappeared while on holiday on the island of Simi, which is located in the eastern Aegean Sea and about 6.5 kilometers from Turkey.
A search and rescue operation has been underway since Wednesday.
Moseley, 67, is believed to have gone for a coastal walk along St Nicholas Beach on Wednesday afternoon while on holiday on the island, which is a popular tourist destination.
Mosley is well known in Britain for his regular appearances on television and radio and for his column in Daily Mail newspaper.
He is known outside the UK for his 2013 book The fast dietwhich he co-authored with journalist Mimi Spencer.
The 5:2 Diet describes how people can lose weight fast by minimizing calorie intake two days a week while eating healthy the other five.
At least 100 rescuers and volunteers, including a helicopter, were searching the area between Agios Nikolaos and the island’s main town for the 67-year-old.
In a statement yesterday, Moseley’s wife Claire said the days her husband was missing had been “the longest and most excruciating”.
“The search continues and our family is extremely grateful to the people of Symi, the Greek authorities and the British Consulate who are working tirelessly to help find Michael,” she said.
The couple’s four children were on their way to the island to help with the search.
He later introduced the Fast 800 diet, a rapid weight loss program, and made a number of diet and exercise films.
Moseley often pushed his body to extremes to see the effects of his diets.
