Let me offer a different interpretation of the same data. Yes, 2/3 of weight was regained after discontinuation. But consider:

• This is consistent with EVERY chronic disease medication ever studied
• 1/3 of patients maintained significant weight loss — who are they and why?
• The metabolic improvements partially persisted even with weight regain
• The data supports long-term treatment, not a "course" of therapy

The takeaway isn't "the drug fails when you stop" — it's "chronic diseases require ongoing treatment." We've always known this.

Agreed, and reference ranges are laboratory-specific.

Thank you for spelling out the reasoning rather than just the conclusion.

I read this differently from james_edin, on substance rather than tone. I would drop the "get everything" instinct further than this thread does. Every extra test is another chance at a false positive, and incidental findings have their own cost in scans, biopsies and worry.

I am eight weeks into deliberately reducing rather than stopping, and the appetite change came back faster than the weight did.

The concept of "metabolic set point" and its relevance to maintenance dosing: the body actively defends a weight set point through hormonal feedback (leptin, ghrelin, insulin, GLP-1). After weight loss, these signals shift to promote weight regain[1].

GLP-1 agonists may work in part by resetting this set point — or at least overriding the counter-regulatory signals that drive regain. This would explain why continued treatment maintains weight loss while discontinuation leads to regain.

Understanding maintenance dosing through this lens reframes the drug from "weight loss tool" to "metabolic set point modulator."
