Ajay Rochester, former host of Australia’s version of the Biggest Loser has let loose about some of the dodgy and unsafe practices on the show. All emphasis is mine:
I also remember how you [Adro Sarnelli, winner Biggest Loser's first series] presented yourself at your final weigh in (behind closed doors and a few days before filming so contestants had time to recover and look healthy)…..you were starving, pale, had shallow breathing, low blood pressure, cracked lips and you were unable to stand on your own two feet – hardly a great advertisement for healthy weight loss….. all the contestants begged me to ask the producers to have you drug tested. I took that request to the producers and was told they didn’t want to know the truth, they just wanted a good winner and told me to shut up and go away. This was one of the many problems I faced in the job I became known for being difficult in…….because I spoke up when I felt it was wrong or that we were being deceitful. I refused to be the face of their online diet club, I refused to sell their shakes and diet bars, I complained when someone who went on to win was living off 200 calories a week, I complained when I had to participate in a cover up for the contestant (who also went on to win) who drank bottles and bottles of tea tree oil (and whose relative was caught smuggling more in) to lose gross amounts of weight and more…..it made me NO friends, but I refused to drink or even sell the Kool Aid. When I joined Biggest Loser I truly believed I would be able to help people learn to love and care for themselves and hoped my message of loving yourself first was more important than chasing a number on a scale. I quickly learned I was never going to be able to do that. And I am grateful for the good that came from that job but I am sick and tired of people like you who forget how hard the struggle can be and the arrogance and judgement you wield while making us feel inferior, forgetting that fat people have feelings too and deserve just as much love and RESPECT as anyone else.
Whether Ajay’s specific allegations are true or not, I don’t think anyone doubts for one instant that unsafe and unhealthy practices take place on the show and are tacitly condoned by the producers and the staff.

I’m glad anyone is speaking about about the unhealthy practices associated with TBL. I do wish Ajay had avoided the “drink the koolaid” phrase because of the 900+ people that died, including 200 children that were murdered at Jonestown.
What I find amazing is the disconnect here. Doing unhealthy things to lose weight are “bad”, but (according to the koolaid) so is being fat. If you’re damned if you do and damned if you don’t, why are you surprised that people will do anything to lose weight?
