In the wake of The Biggest Loser's controversial finale last week, some critics are calling for the NBC show to alter its format, or be canceled altogether.
Rachel Frederickson revealed she'd lost a whopping 155 lbs. - including 45 in the past three months alone - to win this season, and spark controversy.
Now, experts in health, fitness and public relations are weighing in on The Biggest Loser and how it can be improved for future seasons and contestants.
Five suggestions appear below. See if you agree ...
1. Set limits on how much contestants can lose. Those who deem Rachel Frederickson too skinny argue that she was allowed to go way, way too far.
Producers "should put measures into place to ensure [excessive weight loss] doesn't happen again," says crisis public relations specialist Jesse Derris.
Furthermore, she adds, "[NBC] should publicly announce those measures and commit to an education campaign that promotes balanced, healthy living."
2. Slow down the weight loss. It's impossible to lose more than 2 lbs. of fat per week, so beyond that is risking the loss of muscle, which is dangerous.
Celeb trainer Harley Pasternak says: "I think the show gives [the obese] a false sense that they can lose that much weight that quickly, safely."
3. Scale down the intensity of the workouts. On a similar note, critics say the body needs time to adjust to the rigorous workouts they're subjected to.
Pasternak adds, "It gives them a false sense of what you need to do to lose weight. I don't think you need to be flipping giant tractor tires and having obstacle courses."
"Weight loss is not a competitive thing."
4. Provide long-term support. They get sent home, but then what? The contestants' isolated time should be more closely monitored, critics believe.
Says one expert, "90 percent of losing weight is changing behavior, getting to the root of the problem and understanding why the pounds got put on."
5. Cancel the show. Some believe that these myriad ethical and health issues need to be addressed or the show should be axed. Do you agree?
