Do any of the studies control for diet, habits, and lifestyle changes? Don't the studies just sort of give the drug to joe shmoe, keep increasing the dose until it becomes intolerable, and then take him off of it in a handful of different ways?
To me the fact that most people gained back some of the weight hardly even seems like a data point at all.
If there's no way to stop a GLP without gaining back a ton of the weight, then that means that the GLP is doing something horrible to your body, and I just don't buy that. Lose the weight, change your habits, put on some muscle, run some exercise mimetics and metabolic enhancers to help keep the fat cells inactive, lower the dose in whatever way you see fit, and come off. Over years or months.
If that's really not possible then it reduces GLPs into a party trick and a chronic med for the lifetime obese.

Sustained obesity or diabetes management is basically the purpose these drugs were created for. To me, the real strength lies not in starting the weight loss but in keeping it off over time — almost every obese individual has shed and then regained significant amounts at some point, so dropping the pounds is not the toughest hurdle; staying at a lower weight is.
Research spanning thousands of studies and many decades demonstrates that, broadly speaking, people are terrible at keeping weight off, with just a tiny fraction — perhaps around 5% — managing to shed a large amount and hold onto that loss long term. For smaller losses, say 10% or less, or over briefer periods, the figures look somewhat better, yet most folks taking these medications, including those here, are aiming to drop more than 10%, aside from a handful of bodybuilders or people doing it for cosmetic or lifestyle reasons. To my knowledge, no other treatment offers even passable long term maintenance of weight loss beyond 10%, other than GLP drugs or bariatric surgery.
If you can build lasting habits around improved eating and regular exercise, keeping the weight off is achievable. The issue isn't that this approach fails — it's that very few people ever truly pull it off. And the explanation seems clear: if you were already skilled at diet and exercise, you wouldn't have needed to lose weight in the first place; if you weren't and became obese, then altering those patterns and sticking with the change is genuinely difficult.
The notion that needing to remain on these drugs means they're wreaking havoc on your body is simply wrong. Many long term medications that are proven to lower health risks — like statins, blood pressure drugs, or diabetes treatments — only function while you continue taking them to correct a metabolic system that isn't working properly, and GLP's operate the same way. No existing therapy addresses the root cause of obesity, and honestly, scientists don't fully understand how weight is regulated in normal or obese individuals, much less how to fix it permanently. Far from causing harm over time, GLP's are arguably the closest thing to a genuine longevity medication that actually works — with far stronger evidence than any supplement — cutting the risk of numerous health issues, including the most common and serious ones tied to aging, cancer, and cardiovascular disease. The verdict is still out on dementia.
"run some exercise mimetics and metabolic enhancers to help keep the fat cells inactive, lower the dose in whatever way you see fit, and come off. Over years or months."
The trouble here is that right now, no treatments are proven to genuinely accomplish this. Some show promise in mice or rats, but a large share of that research fails to translate to humans. Thus far, the only non toxic drugs demonstrated to sustain long term weight loss in people are GLP's. Overall, I haven't seen solid evidence even on this forum that any of the other peptides significantly affect weight.
