> Do you honestly believe in the so called “free lunch”?

Yes. Why not? A body is a complex biomechanical system, that can be influenced by certain chemicals. Some of them can solve the underlying problem.

Why everything has to be a morality play?

> Why should we believe GLP-1 class drugs are any different?

Why are they any different from, say, antiretroviral drugs? Or from something like statins?

I started the GLP-1 drugs with liraglutide, a predecessor of Ozempic. It works similarly but its half-life is just several hours, so you had to get a daily injection. It has been in use for two decades by now with great results.
