Back on your GLP-1 medication… but confused why it isn’t working this time?

Lots of people stop these medications for valid reasons. Cost, side effects, pregnancy plans, or simply because things were going well and it felt like the right time to try managing without them. But when weight creeps back on and you restart, it can feel really frustrating when results don’t look the same.

In this episode, I talk through why that happens. Factors like muscle loss, metabolism changes, weight regain patterns, and higher stress levels can all change how your body responds the second time around. If you’re feeling stuck or wondering what changed, this episode will help you make sense of what’s going on and figure out your next steps without beating yourself up.
