How do they lose weight so fast on the biggest loser and not have lots of extra skin?

Just wanted to know. I know that sometimes when you lose weight especially as fast as they do. You get excess skin that has to be surgically removed. I remember seeing a show about it a while back. What do the people on the biggest loser do to not have this.





Also, I%26#039;m not sure if they do or don%26#039;t except on TV it doesn%26#039;t look like they do.|||I don%26#039;t know how they do it - I thought Heba%26#039;s arms looked a little flabby at the finale, though. I bought the US magazine with Michelle on the cover and she said she wasn%26#039;t considering any surgery except for a boob job because those don%26#039;t go back - which was a little disheartening for me to hear. I thought with tons of push-ups, they would go back.
