The australian ones my favourite, shannon the male trainer is gorgeous, a proper bronzed oz, i watch the UK and US ones too though, its one of my fave programmes. they very rarely get a big loss in the second week, thats the same in all three, they always say its a notorious week for disappointment. and most of them lost double figures in the first week, thats massive!! dont know how anyone can say they're not losing enough.
on a different note, i bought the biggest loser meal replacement plan last summer but just didnt like it, i like real food too much, but got a lovely mixing cup thing with it (to mix the shakes in) and use it all the time for inspiration!
