I did notice on the first two shows that once each of the contestants had the skin removal surgery (at around 9 months), neither of them had significant weight loss afterwards...I think the guy lost 21 lbs and the girl alot less than that, which I suspect those amounts are pretty much due to the removal of the excess skin. It seemed like their actual weight loss (not loss due to skin removal) slowed down quite a bit during the 9-12 month phase. I hope they do a follow-up on these people to see if they kept the weight off. I know from my personal experience of losing 75+ lbs over and over again (around 8 times) and subsequently gaining it back each time, that losing it is the easy part...it's maintaining the weight loss that is the hardest. When you are down to a small size, it's easy to start thinking of yourself as "normal" and that you can eat like a normal person. You can never eat like a normal person...you have to be diligent your entire life if you want to keep it off. It's really, really hard. :-(
I must say though...I like this guy Chris who helps them...he seems really sincere and as if he emotionally feels their pain. Unlike the other show...the Biggest Loser...the last time I had watched it, the trainers seemed so cold and callous. Of course, I haven't watched it in years...so maybe that's changed.
