I contacted 'Shine' - the company that make the show and they said it hadn't been recommissioned in the UK. Maybe some0one else is making it. Mind you, I was desperate to get on the show and scoured the internet for info, but didn't find any adverts for contestants.
Anyway, the US one is still the best. I know a lot of it is 'staged' but the weight losses are still absolutely awesome. The UK one isn't as good, but it's still amazing the change in people. I agree that I can't stand Angie though - I would LOVE it if Bob and Jillian came over the UK like they did for the Australian series. How awesome would that be?!
