A lot can happen in 12 months – and the determined participants in this programme are hoping for everything from weight loss to new love.

This week, Davina McCall’s guests include Carol, who wants to lose seven stone but admits to a bit of an aversion to exercise (‘I am lazy, basically!’), and Kathryn and Chris, who hope a surrogate mum can make them parents again.

The flashy ‘instant gratification’ format (the guest leaves through one door, Davina walks across the stage, the guest emerges transformed through another door) is quite surreal, but we admit it’s nice not to have to wait to see the results!
