Welcom to the forums MischiefRN!
First off congratulations on your weight loss. It sounds like you are on the right track.
The contestants on The Biggest Loser still do have their extra skin. This is something that just wont go away without surgery or lots of time. Many of the contestants that you seen with all the extra skin gone are ones that went through the surgery already.
I know thats probably not the answer you were hoping for but thats all I can offer.
I hope you continue to stick around would love to hear updates on your weight loss and maybe you can share some of the methods you are using to reach this goal. Like what exercises, diet, ect.
