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.

Following on from TrialNerd_Beth — and this may be the naive question:
Whether extending the interval works as well as reducing the dose, since they are not the same intervention pharmacologically?

Maintenance phase reality on maintenance dosing: reached my goal 7 months ago and now I'm in maintenance. It's a different mental game.
During weight loss, the scale going down is constant positive reinforcement. In maintenance, the scale staying the same is... just... nothing. It's anticlimactic. The dopamine hit is gone.
What keeps me going: lab improvements, physical capabilities, how I feel, fitting in clothes I love, and the knowledge that regain happens when people stop being intentional. I'm staying intentional.

I went to a lower dose rather than a longer interval on the strength of the trough argument in this thread, and the difference in how even it feels is obvious.

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.
