I completely agree that self-hatred doesn't help anyone. Victoria has a point about the value of self-acceptance and self-compassion, and I liked what she said about how she enjoys moving her body.
I agree that there were points where she seemed like she was trying to sabotage other people and deny health risks. Her positivity felt very fragile and insecure. God knows I don't blame her for that, but it made her come across as very defensive and resistant to other views.
I don't think that self-acceptance and adopting healthier habits should be seen as opposites. If you feel your body is acceptable, then you can take pleasure in moving it and nourishing it. I'm not slim but I love going for long walks and I like the endorphins that come from a run, even if I don't love every moment of the run itself. I like rubbish food, but I like nourishing food too, and when I'm feeling good, it's not a hardship to focus on the latter. That feels like a success to me regardless of what the scales say.
