What this video covers
GLP-1 receptor agonist medications, drugs like Ozepic and WGOI are changing the obesity medicine world, that’s for sure. But there are a lot of really strong opinions out there. Well, this video is going to be something entirely different in a couple of ways. First, it’s a compilation of shorter past videos packaged so you can listen to complimentary collections in one place like a movie or a podcast.

Key points, in the speaker’s own framing
- About a year ago, I thought if I said GLP1 or GLP1 receptor agonist, your average non-medical person would have no idea what I’m talking about.
- It makes the point that the benefits of GLP1s are not just related to weight loss, but also that, and now I’m quoting, a potentially unifying mechanism of action for GLP-1 receptor agonism is the reduction of inflammation.
- And then they also treated some mice with a GLP-1 receptor agonist and observed reduced inflammation in the GLP-1 treated mice.
- And interestingly in these mice lacking the GLP-1 receptor in those tissues GLP-1 could still reduce inflammation.
- And all this strongly suggests that it’s the action of GLP-1 on the brain that mediates the systemic whole body anti-inflammatory effects of GLP-1 drugs, at least in animals.
- There are quite a lot of options potentially a few family of compounds that could say boost GLP-1 levels including TGR5 agonist, FXR inhibitors, DFMA, and of course GLP-1 receptor agonist.
