Crossing the 500 lb mark should be a Come-to-Jesus moment for most people. I think for AL, it was honestly her liberation. She's free from having to try anymore. You can sense her relief and resignation about that, even in this video as she reaches for a 500 calorie Dove bar. Nobody but her most loyal followers expects her to succeed on her own at this point without medical intervention. She doesn't believe it's possible, either. So her options are:
1. give up. eat whatever. who cares.
2. try again. endure discomfort. maybe fail. maybe succeed too.
We all know the path she's chosen for herself. Honestly, despite how insufferable of a human being she can be, it will be sad to hear of her passing. Sad, just not surprising.
