Surprising Findings
The diabetes drug liraglutide doesn’t directly improve pancreatic function.
Many assume GLP-1 drugs like liraglutide directly 'heal' the pancreas or improve insulin production. This study shows the improvement is fully mediated by weight loss — the drug itself has no significant direct effect on proinsulin after adjustment.
Practical Takeaways
Focus on losing 10–15% of your body weight through diet and exercise to improve your body’s insulin production and reduce diabetes risk.

Losing weight by turning on a specific brain and gut signal (GLP-1) can help improve health problems linked to obesity, like high blood sugar or high blood pressure.
For adults with obesity, taking liraglutide plus metformin helps you lose more weight than just taking metformin — about 4 extra pounds on average over 6 months.
If adults with obesity lose 10–15% of their weight over about six months, their body's insulin processing tends to get better — especially in how it handles a substance called proinsulin — and this improvement sticks even when you account for other health factors.
When people with obesity lose belly fat, their pancreas may start working better — especially in how it processes insulin — and this seems to happen because of the fat loss itself, not just weight loss in general.
Adults with obesity who took a drug called liraglutide for 6 months, while eating less and exercising, lost more deep belly fat than those who didn’t — and the study says this medicine might help burn that stubborn fat better.
