Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The "earlier than weight loss explains" argument is weaker than this thread makes it sound. Blood pressure and inflammatory markers move fast and are downstream of early weight loss, so the mechanism is not as cleanly separable as the summaries imply.

I understand the skepticism — we've all seen "miracle" weight loss solutions come and go. But consider what makes GLP-1 agonists different:
- Phase 3 RCTs with thousands of participants (not 20-person pilot studies)
- Published in NEJM, JAMA, Lancet (not press releases)
- Replicated across multiple independent research groups
- Proven cardiovascular and renal benefits beyond weight loss
- Biological mechanism fully characterized at the receptor level
This isn't a fad — it's a new drug class supported by the highest level of clinical evidence. The comparison to past fads is understandable but inappropriate.

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off amlodipine entirely! My cardiologist is thrilled.
If you're on BP meds and losing weight on a GLP-1, monitor your BP at home regularly. Hypotension symptoms (dizziness, lightheadedness when standing) mean your BP meds may need reduction. Don't wait for your next scheduled appointment — call your doctor.

Cardiac biomarkers and cardiovascular risk: my cardiologist ordered advanced cardiac labs given my family history. Results were encouraging:
- NT-proBNP: 70 pg/mL (normal, cardiac function preserved)
- Lp(a): 50 nmol/L (genetic, unchanged — expected)
- ApoB: dropped from 140 to 95 mg/dL (excellent response)
- Coronary calcium score: 0 (unchanged from baseline — reassuring)
The ApoB reduction is particularly meaningful — it's considered the best single predictor of cardiovascular risk. GLP-1 therapy seems to improve this consistently.
