The mechanism that matters here is not stomach emptying, it is central.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. I will report back once I have actually tried it.

Adding the clinical framing, because it changes how the question reads.

Dizziness and cardiovascular risk: I was lightheaded for the first 3 weeks. Root cause was a combination of reduced caloric intake and mild dehydration.

Fix: minimum 80-100oz water daily, don't skip meals even if you're not hungry (eat small protein-rich snacks), and stand up slowly from sitting/lying positions. Also check your blood pressure — GLP-1-induced weight loss can make BP meds too strong, requiring dose reduction.

The dose-response is real but shallow at the top.

I will push back on the "any working dose is fine" framing. The maintenance evidence sits overwhelmingly at the top studied dose, and the extension data shows regain tracking dose reduction rather than tracking stopping. Holding low is reasonable; pretending it is evidentially equivalent is not.

SELECT is the trial that changed the framing of this class, because it was an outcome trial rather than a weight trial: about a 20% relative reduction…

...we're creating a generation dependent on cardiovascular risk...

I understand the concern, but consider this analogy: are we "creating a generation dependent on" blood pressure medication? Cholesterol medication? Thyroid medication?

Obesity is a chronic disease with biological drivers. Treating it with medication is no different from treating any other chronic condition. The "dependency" framing implies weakness or moral failure — neither of which is accurate.

If ongoing medication is what keeps someone healthy, that's successful treatment, not dependency.
