A man from Chandlers Ford says his life has been transformed after losing nearly 20 stone in four years.
Jon Vidler weighed nearly 34 stone and could barely walk up the stairs.
He know weighs less than half that, at his target weight of 13 stone.

Jon's old work trousers are a reminder of how far he's come, with a waist band of 66 inches.
He's halved that over four years, thanks to a complete rethink of his approach to diet and exercise.
Jon is climbing Mount Snowdon next month with a team of fellow dieters, which he says would have been unthinkable before he lost weight.
