Taking the question as asked, rather than the general version of it. The mechanism that matters here is not stomach emptying, it is central. GLP-1 receptor agonism in the arcuate nucleus stimulates POMC neurons and suppresses AgRP/NPY signalling, which is why the effect is appetite and food salience rather than physical fullness. Delayed gastric emptying largely tachyphylaxes over the first months; the appetite effect does not.

All true, with one condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.

Agreed, though "tolerable" needs defining. A dose you tolerate by eating almost nothing is not tolerated, it is being paid for somewhere else — usually in lean mass, sometimes in adherence three months later.

Clinical perspective, offered as context rather than as advice.

Insurance coverage hack for cost and coverage: if your insurance denies brand Wegovy/Ozempic, consider these alternatives:

1. Prior authorization appeal with peer-to-peer review
2. Manufacturer copay card (for commercial insurance)
3. Patient assistance programs (Novo Nordisk, Eli Lilly)
4. Compounded medication from a 503B pharmacy ($149/month)
5. Canadian pharmacy (requires prescription, ~40-60% savings)

Don't let cost prevent access to effective treatment. There are options at every price point.
