I am going to agree that it is not healthy to lose so much weight in that amount of time. It definitely does a number on the body which is why quite a few of the people gain back some of the weight. Part of that though is also that they go back to their old habits. They don't have the support after the show, the doctors that are with them on set every day, the trainers that push them, the people that buy/make their food, and...they have to go back work (which is where I put on most of my weight...fricken food days
)
It would be nice to see all of the contestants be able to stay throughout the full season, but I don't see NBC changing it. They think that they've got a good thing going right now.
I was secretly hoping Brown would go home but I know they need to be there for their kids so I was fine with Green going home.
