Weight loss: Obesity and reality TV's pros, cons
"They fret that the shows' emphasis on body image can encourage eating disorders and other dangerous behaviors. With participants losing as much as 30 pounds in a single week, they run the risk of heart problems, bone loss and electrolyte imbalances, among other problems. Some contestants on 'The Biggest Loser' have admitted to fasting or dehydrating themselves to drop weight, and at least two had to be hospitalized after they collapsed during a one-mile race."Bottom line: If you are obese and need to lose weight, lose weight safely. Get proper supervision, or at least join a programme such as Weightwatchers or Jenny Craig and follow their programme. They've spent decades working out how to take kilos off without killing their clients.
If a New Zealand television programme ever runs a biggest loser type programme, beware, they won't have as big a budget as the US programmes and the chances of them having as much personal supervision of the contestants as the US show has are pretty minimal.
