Ah, you might have seen my reply to someone else addressing the free will question from a philosophical angle, but despite also being in the life sciences, I never expected you were thinking about it biochemically.

I think it's obvious that we don't have "free will" in that sense, it had never really occurred to me to consider otherwise- people are definitely quite driven by instincts, neurochemicals, etc. they they can't consciously choose.

However, I think my comment in the other thread still applies- that for an individual, it doesn't really matter one way or another- your firsthand experience is still going to be one of exercising your will to increase the odds of getting outcomes you want in life, or choosing not to, and definitely not getting them.

But there is some biological clue here about who we are, and how our brains work that is fascinating, when you consider the breadth of human health problems and challenges that these GLP-1 agonists influence. I can't wait to see what more is learned about this in the future.
