She has confirmed a few times by now that she's only been doing the gaining for her partner. She doesn't want to be immobile, hates the thought of being 1000 lbs., and she overshot her last posted goal of 730 to get to 800. I think she is very divided on this whole thing. She likes to eat all the delicious food and making her partner happy and making the extra cash, but she has days she hates her body and how big she has gotten. Someone once asked her if she could flip a switch and magically become 100 or 1000 lbs, she said she'd choose 100.
So yeah not sure how much further she is going to take it. It would be amazing if she kept going but i won't be shocked if she stops.
