Manuel Uribe, 43, holds the record for the world’s fattest man in the 2007 Guinness Book of Records. The Mexican said he had from dropped to 41 stone from 93 stone since February, reports the Daily Telegraph.

Mr Uribe is to marry a widow named Claudia, on 26 October in his hometown of Monterrey, northern Mexico.

"It will be a hefty wedding, on a large scale, but with a low-calorie banquet," he said.

The Mexican reached his Guinness record weight of 88 stone in 2007 after years of a diet of pizza and tacos.

Bed-bound and unable to look after himself, Mr Uribe made an impassioned plea on Mexican national television for help in January 2006.

Doctors and dieticians the world over responded to his appeal, with a team of doctors from Italy, the US and Mexico leading the attempt to restore Mr Uribe to a healthy weight.

Following the wedding announcement, Mr Uribe has been inundated with offers of sponsorship from international magazines and television stations.

Mr Uribe thanked God for the "miracles he gave to a man who was on the edge of suicide and who today knows love".
