Network Ten dismissed these allegations, arguing that Donovan had simply not survived the application process. Health risks: The show received further criticism, being attacked by exercise experts for promoting risky weight loss techniques that may endanger the show's viewers. There was also much criticism when news leaked of contestant Jules, then unknown, was forced to quit after multiple health scares and hospital visits. An eating disorders support group, The Butterfly Foundation, commenting on Chris's achievement, warned that such a dramatic weight loss could be a health risk. New trainers: With Shannan and Michelle introduced, this was a tactic to make sure that in the future series of the Biggest Loser, the two trainers will be Shannan and Michelle. By doing this, they hope that the Australian public can appreciate them as much as Bob and Jillian and to make future series of Biggest Loser an all Australian cast. The length of the show compared to the American version was accused of being too "bloated" with over 3 hours of extra footage for each "episode" or week, but at the same time, the type of participants used in the show are a good change from regular reality television "wannabes". The show averaged more than 1,000,000 viewers each night, peaking around 1.56 million viewers for one weigh-in show and 1.31 million viewers for one elimination show. The season premiere attracted only 1.17 million viewers compared to the first season premiere of 1.4 million, although depending on what was happening with the Cricket on Channel Nine, the total audience peaked at 1.45 million. The ratings were considered a great success by the network, receiving a large portion of the target demographic (39.2% commercial share in demographic ages 18–49, and 42.6% of the 16-39 demographic). The season finale was the ratings success, being the highest rating episode of the show and ranking number 1 for the day with 1,995,000 viewers. The following are some of the ratings achieved from the highest rated episodes. Unless otherwise stated, sources are gathered from OzTAM as a primary or secondary source.
