Not enough evidence
GLP-1 drugs cut cardiovascular events partly independent of weight loss.

Short answer
Two things beyond weight. GLP-1s cut cardiovascular events partly independent of weight loss, likely through anti-inflammatory effects. They also curb alcohol and compulsive cravings. The anti-aging claim is unproven outside obesity and diabetes, and high doses carry depression and rare eye risks.
GLP-1 drugs are worth taking for people with obesity.

GLP-1 drugs cut cardiovascular events partly independent of weight loss. Past that, the evidence splits.
Zachary Knight, a guest on Andrew Huberman's show, says the heart benefit looks partly independent of weight loss. His candidate mechanism is the "inflammatory reflex," which suppresses inflammation throughout the body. Preventive cardiologist Aaron Mikos, a guest on Peter Attia's show, adds that GLP-1s cut cardiovascular events through blood pressure, lipids and effects against artery plaque.
Blood sugar is not the whole story.
Addiction is the better-grounded off-label signal. Attia describes "striking success in silencing cravings" in alcohol use disorder that resisted other treatment. Anna Lembke, an addiction psychiatrist, and Keith Humphreys, guests on Attia's and Huberman's shows, call GLP-1s a promising frontier for alcohol and compulsive behavior.
They see a possible "two-for" alongside obesity. Lisa Mosconi, a guest on Attia's show, and Eric Topol, a guest on Mark Hyman's, note early interest in brain protection and Alzheimer's, again through the anti-inflammatory route.
Attia will not sign off on the claim that a GLP-1 slows aging itself. The data covers people with obesity or diabetes, so no one can separate an aging effect from the weight effect. Ben Bikman, a guest on Rhonda Patrick's show, flags higher depression risk and rare blindness (NAION) at higher doses.
He calls the drugs a "temporary tool, not a lifetime solution." He adds that the human evidence is entirely correlational, so the rest is speculation and modeling.
Hyman, on his own show, is the negative voice on the record. He says no one should take a GLP-1 for longevity, citing risks that include gastroparesis, bowel obstruction, pancreatitis and lost lean muscle.
