Short answer first, then the reasoning. The liver data is among the strongest non-weight findings in the class. The semaglutide MASH programme reported a large advantage over placebo on MASH resolution, with a substantial minority also achieving fibrosis improvement — and fibrosis is the endpoint that predicts outcomes. Mechanistically it is reduced hepatic lipogenesis, increased fatty-acid oxidation, less hepatic inflammation, and possibly a direct effect on stellate-cell activation.

Agreed, and ALT falling is not the same as fibrosis improving. Enzymes are a crude proxy; FIB-4 or elastography is what tells you about the thing that matters.

Alcohol simply stopped appealing, which I did not expect and which has been more socially complicated than the weight loss.

Second this.

Adding the clinical framing, because it changes how the question reads. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.
