> The underlying mechanisms (reduced inflammation, improved fat distribution, better metabolic health) aren't unique to that group

Those are causes, you can't just invert it (again) and call them mechanisms for anti-aging... Those things are side effects of obesity and diseases causing obesity, there is no evidence or reasonable basis here to suggest there would be any "anti-aging" effect in healthy people without those problems.

Similarly "Ozempic shows anti-gravity effect in humans!#11"... assuming you have unhealthy excess fat to lose.
