...regarding food noise mechanism of action...

To build on this — the mechanism is more complex than "it makes you less hungry." GLP-1 agonists:

1. Activate hypothalamic satiety centers (appetite reduction)
2. Delay gastric emptying (prolonged fullness)
3. Potentiate glucose-dependent insulin secretion
4. Suppress glucagon secretion
5. Modulate reward pathway dopaminergic signaling
6. Reduce hepatic lipogenesis
7. Have direct cardiovascular protective effects

It's a multi-target drug with systemic metabolic effects. Understanding the mechanism helps us predict and manage side effects.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Taking it to my next appointment.

This is where I part company with the consensus forming above. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.

One concrete data point for the thread. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. No action needed from anybody.
