I agree she does look worryingly thin. But you can’t tell how healthy someone is by the way they look. Someone can be overweight and healthy, someone can be very thin and healthy, someone can be average weight and very unhealthy.
However, it seems to me that the whole Biggest Loser show promotes unhealthy behavior. I’ve read articles about how the contestants exercise unhealthy amounts of time, often get injuries, dehydrate themselves or do other drastic measures before weigh-in times to be their lowest. Then of course many of them gain a lot of their weight back after the show. I’ve heard around half of the contestants gain most or all of their weight back.
All of their behavior of course makes sense for a game show where they have the chance to win a lot of money. I would dehydrate myself and exercise too much and do other things if it helped me win $250K. The problem is if The Biggest Loser doesn’t just present itself as a gameshow, but if it instead presents itself as good examples on how to lose weight and be healthy.
Frederickson was smart to get that thin, I don’t think she would have won if she didn’t. She started at 260 lbs so I think numerically it would make it harder for her to win rather than people who started at 300 or 400 pounds. I don’t know if Frederickson is healthy or not now. I hope she is regularly seeing some doctors, since I think that amount of weight loss fairly quickly can maybe cause issues. If she is too skinny, then hopefully she can work with doctors on a plan and gain 5 or 10 pounds or however much to get to a healthy point. But she wasn’t at all stupid or crazy to get down to the weight that she did.
