What happens when GLP-1 medications change more than just your appetite?

If you’re considering anti-obesity medications, it’s normal to wonder what else they might affect beyond hunger. In this episode, I respond to a thoughtful listener question: If food and alcohol have been your go-to coping tools, what happens when they no longer provide comfort?

We explore how GLP-1 medications can dampen the brain’s reward response—not just to food, but to other pleasures as well—and what that might mean for social drinking, emotional regulation, and mental health. I also unpack the rare but real risk of mood changes, why it’s so important to have fulfilling habits in place before starting, and how, for many people, these medications unlock a new level of physical freedom and possibility.

If you’re weighing your options or just want a clearer picture of what life on GLP-1s can look like, this episode offers a grounded, honest perspective—plus why having the right medical support really matters.
