I'm looking forward to seeing Alison on this, I bet she'll be brilliant! She did so well on Celebrity Fit Club, and came across as lovely too. I think she lost the most weight, at just over 3 stone, but she didn't win the series as it was more about lifestyle changes than actual weight loss.
James Whittaker the former Royal correspondent was the overall winner, and he did fantastically well. What a transformation! Apparently he had a lot of potentially life-threatening problems, and was on loads of medication, but during the course of the series he had gradually been taken off most of it and was feeling on top of the world!
