Analyzing Claims of GLP-1 Health Benefits

I got a question from reader Giana who asked:

I feel like I’ve seen a hundred news reports claiming that the GLP1 drugs will cure anything and everything…joint pain, heart attacks, addiction, on and on and on. Is it possible that they can do all of these amazing things or is this just the new snake oil?

I’ve also seen a bunch of claims about the healing powers of GLP-1 drugs. It is possible that GLP-1s have health benefits, but there are some potential issues with these studies that I want to point out.
