I suspect that's a combination of two things:
1. A hamfisted attempt at being "quirky and relatable" with some added chaos for their audience. It's an intentional performance to show things like the toilet paper, Asa lumbering around the pool, Priscilla flopped out on that raft, etc as a way of making the audience feel that these people are just like them. Most everyone is awkward and feels unhappy in their skin in some way; it feels good as a viewer to see someone "famous" being awkward or doing something dumb too. It makes them relatable. Influencers know this. They intentionally aim to strike a balance between flaunting wealth and still being a regular Joe. This sort of thing seems to be more common on Youtube than IG, and and the relatable awkwardness of Tiktok is a whole different beast, but it all boils down to the same thing. You want viewers to envy you(buy what you're selling) while making it feel like those viewers can also achieve the wealth or fame you're flaunting. You can't be too fancy about it because that alienates viewers.
2. Defense mechanism - denial. She's incredibly insecure about her appearance and how she comes across to people, like painfully so. It's agonizing in more ways than one for her to be not only that fat, but to have publicly lost & regained so much weight. Remember how much emphasis she puts on her hair, how for a long time she absolutely refused to ever be filmed in her PJs or how she had to be done up for the camera, how Asa admitted he had to carefully edit out her huffing and puffing (which he's absolutely having to do again, but can't get it all in favor of content). She cares deeply about how she looks to others. She can't present the image she wants to present whatsoever, so in acts of self-preservation
(and I don't mean physical self-preservation, but the much deeper preservation of self, psychologically speaking)
she escapes into a fantasy world where she really did lose 105 lbs, where she's simply chunky and confident about that, where she's a dainty Southern belle, an accomplished entrepreneur, a successful business owner, a great mother with perfect children and a handsome military husband, where she's everything she wants to be but can't actually reach. It's intense denial so she can pretend to feel good about herself, and many days she likely does feel good about herself, but the thing is that reality constantly lurks under the surface façade for her. Reality, as it always does, creeps in periodically and she's forced to painfully recognize it and it kills her inside. So she's then forced back into her fantasy world from point 1 above.
Think of it like the crazy conspiracy theorists holed up in Dallas waiting for JFK Jr and Sr to make their return. They're so deep in the bullshit they will not - they cannot - face reality. They've invested too much of themselves already.
Acknowledging shame like that is enough to cause pretty intense mental damage, enough so that the mind will do what it can to protect itself. It's similar to what Priscilla does; acknowledging shame would destroy the entire fantasy world she's created for herself and leave her with nothing.
