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…

Metabolic syndrome resolution on cardiovascular risk: I went from meeting 3 of 5 diagnostic criteria to meeting ZERO after 14 months of treatment.

The 5 criteria (and my journey):

  1. Waist circumference: 53" → 35" ✅ Resolved
  2. Triglycerides: 225 → 110 ✅ Resolved
  3. HDL: 37 → 57 ✅ Resolved
  4. Blood pressure: 145/95 → 118/72 ✅ Resolved
  5. Fasting glucose: 120 → 89 ✅ Resolved

Metabolic syndrome reversal is, in my view, the most medically significant outcome of GLP-1 therapy.

Following on from ingrid_STO — and this may be the naive question:

Did your prescriber agree with that reading, and if not what was their objection?

CRP reduction on cardiovascular risk — this is the lab result that excites me most:

Baseline hsCRP: 11.0 mg/L (high cardiovascular risk)
Month 6 hsCRP: 1.5 mg/L (moderate risk)
Month 12 hsCRP: 0.9 mg/L (low risk)

This level of inflammatory marker reduction is comparable to what you'd see with statin therapy. Combined with the weight loss, my 10-year ASCVD risk score dropped from 18% to 4%. My cardiologist is genuinely impressed.

...cardiovascular risk is just another fad...

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.

Lp(a) and cardiovascular risk: a nuance that matters. Unlike most lipid markers, Lp(a) is 90%+ genetically determined and doesn't really change with weight loss or GLP-1 therapy.

My Lp(a) has remained at 41 nmol/L across all time points. If yours is elevated (>50 nmol/L), you need additional risk mitigation strategies regardless of your GLP-1 response. Don't assume your medication is covering all cardiovascular risk factors.
