Schmeck,
I had not watched the finale when I saw this thread and I did think "I wonder if it's just a case of society doesn't know what a normal/lean body type looks like anymore?". I really judged ahead of time. And thought the winner is probably just a little thin, who cares.
AND -
I truly believe some people look very healthy lean/thin - and look good small because that's their body type and they are meant to be that way, no wonder what the ridiculous BMI says.

Many.
So I understand your point about yourself. You know where you look and feel your best.

But she's not one of them, in my opinion. Because it really goes against her body type. She looks horrid. She's a young woman who looks like she's late thirties. No amount of dehydration could cause a girl that young to have deep lines down her face, in my opinion.
All the contestants were so excited to see her, you could tell. And the ones that they had on camera seemed horrified by her look. So obviously it was something in person.
And this was a tell tale sign for me - she laughed at her prior self in a weird manner and kissed goodbye and waved. I know most people think that that is normal and just a way to say goodbye to old ways/bad habits/bad health. I don't.
Hopefully, she'll put some pounds back on.
And be fine and was just being overly competitive because that nature was apparent all season. It's not the show's fault, it's in her.

And I thought Lumi looked fantastic and not too thin at all. To me, her home win was something. I thought she was voted off too early, she was one of those weeks where they did get to decide.
