ONE of television's biggest hits has come under fire for giving viewers unrealistic expectations.
Yamba personal trainer Dane Mitchell said although he was a regular viewer of The Biggest Loser, he was disappointed producers were giving fans false expectations about what could be achieved in just a few months.
"Losing 70-plus kilos in 12 weeks is just not realistic," Mr Mitchell said.
"Contestants see dramatic results because they are in a controlled environment without temptations - apart from the planned challenges - and their sole focus for 12 weeks is exercise and eating; often training for six hours a day.
"Find me someone with a family, a job and social commitments who can do that."
Mr Mitchell said the show didn't focus on what was important - creating realistic goals.
"Each week there is a weigh in and we see them crying because they've only lost 1.5kg's that week," he said.
"It's absolutely ridiculous; doctors recommend losing just 0.5-1kg a week.
"The contestants aren't learning how to avoid real world temptations like the chocolate isle at service stations.
"They are actually rewarded with immunity for eating food they know is detrimental to their health at temptation each week."
The key to losing weight and keeping it off was not a secret, he said.
It was a simple combination of healthy eating, lots of water and regular exercise.
"You need to eat mainly unprocessed foods - meat, vegetables, nuts and fruit. You'll have more energy and you won't feel hungry or bloated.
"Unfortunately, many people are searching for that magical weight loss secret, or the next breakthrough diet or quick fix - it doesn't exist."
Pared back, Biggest Loser was just a 'survival of the fittest' show, he said.
