In earlier episodes, you may notice a blonde woman named Miria (pronounced Maria) present, yet she is only there for a short amount of time. So who was she, and why did she leave?
At the time of its launch, The Fab Fatties were actually The Four Fab Fatties but underwent a rebrand now that Miria has been excommunicated from the tribe. This fallout seems to have happened sometime around March 2024, and no one but Miria seems interested in explaining the behind-the-scenes of what the nature of the disbanding was (and unfortunately even Miria's post is relatively vague). Whatever took place must have been quite thunderous, as they specifically untagged Miria from all posts involving her on the official Instagram page itself, though videos featuring her remain uploaded.
This is what Miria had to say about it.

"Hi friends, It is with mixed emotions that I announce I'm no longer associated with 4 Fab Fatties or CLT Plus. Due to personal and professional differences, I've chosen to step away. I encourage each and every one of you to do what is best for your own peace and sanity. I will continue to support fat community and tell my story. I'm looking forward to doing so in a safe space where my voice and opinion is actually appreciated.
I'd like to remind my fellow introverts that just because someone else's voice is louder, doesn't mean that your voice isn't worthy of being heard. Surround yourself with people who see that and appreciate you for who you are.
Don't ever let someone else's insecurities take away from who you are.
That's all for now.
I'm Fat.
I'm Fab.
And I'm currently accepting Friendship applications.
XOXO,
Miria"
What will now follow is purely 100% weapons grade autistic speculation so please take it with the largest hunk of salt you can find, but I suspect Miria was driven out by Ally, who had
this post to make before Miria announced her departure - note her stating that she "won't dim her light to make others shine brighter." She also had another reel that stated that "
some people won't like her," and has cried in some episodes about trying to make herself more "digestible" to others.

The reason I theorize this is because that in some episodes, Ally has apologized to Alyssa (specifically) for being toxic or mean towards her off-camera and cites that her BPD causes her to be caustic at times. Additionally, if you watch the earlier episodes with Miria, you'll notice that Ally definitely bulldozes over Miria in conversation often and seems actually pointed in some of her remarks towards her in Miria's final episode (which is #9). The interesting part? That episode was March 6, 2024... and Miria was ousted by
March 20 of the same year, and by March 24, the Four Fab Fatties had rebranded to The Fab Fatties and essentially acted as if Miria had never been there at all.
There is no smoking gun here, but my guess is that loud-mouthed, aggressive Ally drove out the more soft-spoken Miria and used force of personality to ensure that she stayed and Miria left (as Miria supposedly was the one to bring them all together originally).
I have no solid evidence that this is what happened, and we'll likely never know, but it's part of why I believe that not only are all three cows, but Ally may be the biggest cow of all.
