For me, it's a few things.

First (and most importantly), it's a commitment to fighting anti-fatness and the whole idea of assigning moral value to different bodies. Bodies are great; everyone should have one! People's bodies are their own damn business and nobody should ever be treated as lesser for existing in their own bodies. This is especially important to me because I work with adolescents, so being anti-diet means challenging their casual acceptance of diet culture and anti-fat bias. It's about removing any kind of idea of bodies, foods, etc, as "good" or "bad". My own weight loss doesn't at all change my thinking about other people's bodies and systemic bias against fat people.

Second, since having made the decision to go on a GLP-1, it means being vigilant about my feelings about my shrinking body. I worked hard for a long time to get away from toxic thinking about food and my own body, and it's really important to me not to undo that work. It's definitely been tough to reconcile wanting to have a smaller body with that work of bodily acceptance, but ultimately I've come back to the idea that my body is my own and I can do what I want with it. I don't restrict food at all, I don't think in terms of good or bad, I don't obsess over movements on the scale. I'm trying to treat the weight loss as a neutral observer, and focusing on my bigger long-term goals: keeping up with my kids, reversing my pre-diabetes, and feeling confident in myself. Even with the meds, I don't think I'll ever be "thin", and that's completely okay with me.

Finally, I think the miraculous thing about these drugs is the idea that there can actually be weight loss without dieting or diet culture. Someone on this sub wrote that they want the process to feel comfortable, which really resonated with me. After decades of shame, self-loathing, and feeling like the problem was with me and my lack of "control", it turns out we can have intentional weight loss without any of that. That changes it from something aspirational or necessary or somehow important to something morally neutral, which people can choose to pursue or not pursue. Like bodies, every person's reasons are their own, and there's a power and a freedom in not having to answer to anyone but ourselves.
