I watched the first episode the other day and I think they have put a bit more money into it this year. In the trailer for it as well it showed them doing challenges and temptations so it is seeming a lot better than before. I am sure they must have seen series 10 of the US version before they made the UK version as the first thing they did is exactly the same as the US one.
I love any weight loss show at all. Biggest Loser US, Aus and UK, fat families and X-weighted (canadian). Sometimes I can just about bear you are what you eat but only for the actual weight loss story not tips!!
