She did keto/carnivore last year and lost weight. She even lost enough weight that her breathing audibly improved. However, her video views plummeted, and she claimed she could not financially sustain content that did not involved gorging herself on-camera with gross food. She started eating the typical junk again, and she's now back to being in really terrible health (even by her own low standards).
I no longer remember how much weight she lost last year, but it was enough to start making a difference. She got a lot of support from people who wanted to see her do well, but, when she felt the financial pinch, she went back to eating rather than trying . . . anything else at all to supplement her income.
She's my death pool pick. She's older than some others, and she's in really terrible health.
