Read the primary source rather than the write-up and the two do not agree, so here is what is actually in it.

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 in major adverse cardiovascular events in people with established cardiovascular disease and overweight or obesity, without diabetes. The effect appeared earlier than the weight-loss curve can comfortably explain, which is the basis for arguing that some of the benefit is direct — anti-inflammatory and vascular — rather than purely a consequence of weight.

Where I think it is weakest: the follow-up is short relative to how long people actually take these drugs, so durability is an assumption here rather than a finding.

The bit I cannot resolve on my own is how much of the SELECT benefit is plausibly independent of the weight loss, and whether that distinction changes anything practical. Practical detail welcome, however dull — the duller the better.

Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

Senior perspective on cardiovascular risk: I'm 68 years old and started this journey skeptically. My cardiologist recommended it after years of failed interventions.

10 months later: down 56 lbs, more mobile, pain reduced, medications simplified. My quality of life has improved dramatically. I wish this existed 20 years ago.

To other older adults hesitating: the SELECT trial proved benefit in our age group. You deserve to feel good in your body regardless of age.

I read this differently from LeilaHI, on substance rather than tone. 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.

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.

Can confirm. Same sequence, different timescale. I had assumed I was the exception until I read this.
