The reactions from everyone, including a couple of the trainers, was that of shock:
The general reaction was that Rachel was much too thin to be considered healthy. Some viewers were enraged that the show would allow it- that in the future there should be a rule against someone being underweight.
My opinion is that this was a game for $250,000 and Rachel wanted to win. On another level I think it's obvious that she had a problem with food before, and that's how she had intimately gained so much weight. Now... She still probably had a problem with food- but the opposite issue. She is afraid to eat and when she does, she feels the need to work off those calories immediately.
I'm not going to judge her because I don't know the whole story. I am amazed at the transformation and inspired to keep on my journey- but I do hope the girl was determined to get this small for the money, and will ultimately add a little more lean muscle to her tiny frame. I think her being underweight for a short period of time is healthier than her being overweight for what could have been the rest of her life.
