Surprising Findings
Appetite rebound wasn’t just a return to baseline—it was a hyperactive surge, with 78.5% eating 300+ extra calories daily and reporting extreme hunger.
Most assume hunger returns to pre-treatment levels, but this shows the brain’s hunger circuits become more active than before treatment.
Practical Takeaways
If you’re on semaglutide, plan for weight regain after stopping—consider behavioral support, gradual tapering, or maintenance strategies before discontinuing.

Even after people stopped taking semaglutide, some of the good effects on fat breakdown in the liver and fat tissue stayed around, likely because certain cellular signals that help burn fat stayed active and others that store fat stayed quiet.
When women with obesity stopped taking a weight-loss drug called semaglutide after 36 weeks, most of them quickly gained back weight and felt hungrier than before.
When women with obesity stopped taking semaglutide, their gut bacteria changed in a way that’s linked to lower levels of a helpful bile acid and reduced activity in a brain region that helps control appetite.
When people stopped taking semaglutide, their brain started signaling hunger more strongly and fullness less strongly, making them feel hungrier again.
When people stop taking semaglutide, they often gain weight back and feel hungrier — and this might be because their gut bacteria and metabolism go back to how they were before, which could be telling their brain to eat more.
