Operation Transformation returned to screens with a bang this week, with five new leaders baring their souls on screen in the hopes of building a better lifestyle.
Host Kathryn Thomas launched the 16th season at the helm, alongside an expert panel made up of new dietician Sophie Pratt and returning experts Dr Sumi Dunne, Dr Eddie Murphy and Karl Henry.
But a lot has changed since the hit show's premiere on radio in 2008 with Gerry Ryan at the helm - with changes all across the board from presenters, expert panels, and a shift from a focus on weight loss to wellness over the years.
