Epigenetic implications of GLP-1 therapy and maintenance dosing: emerging evidence suggests that sustained weight loss and metabolic improvement may produce epigenetic changes (DNA methylation, histone modification) that persist beyond drug discontinuation[1].
This is speculative but fascinating: could long-term GLP-1 agonist treatment "reprogram" metabolic gene expression? If so, it would explain why some patients maintain weight loss better than others after discontinuation.
More research needed, but the concept of pharmacologically-induced epigenetic remodeling is intellectually exciting.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Printing the relevant bit and taking it with me.

This is where I part company with the consensus forming above. I think this board over-worries about lean mass. Some lean loss is obligatory — you need less muscle to move a smaller body, and preserving mass you no longer need is not a health outcome. The question is whether strength and function held, and mine did.

LindaRN_retired said:...I stopped maintenance dosing and regained all the weight...
This is a really important data point and I appreciate your honesty. The STEP 1 extension data showed ~2/3 of weight regain within 12 months of discontinuation.
This doesn't mean the drug "doesn't work" — it means obesity is a chronic disease requiring ongoing treatment, just like hypertension or diabetes. We don't criticize blood pressure meds for "not working" when BP rises after stopping them.
The framing matters. maintenance dosing is a treatment, not a cure. And that's okay.
