Genetic variation in the NBEA gene predicts weight loss response to GLP-1 receptor agonists (GLP-1RAs), with specific NBEA scores identifying individuals likely to be highly responsive or non-responsive to treatment.
If you are prescribed a GLP-1RA like semaglutide or liraglutide, ask your doctor about genetic testing for the NBEA gene. This test can predict whether you are likely to lose significant weight (top 20% responders) or not respond at all. This helps avoid wasting time and money on medications that are unlikely to work for your specific biology, allowing for a more personalized and effective obesity treatment plan.
These findings indicate that NBEA genetic variation is predictive of GLP-1RA weight loss and may support future efforts to identify individuals likely to experience significant weight loss with GLP-1RAs, enabling personalised obesity treatment strategies.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
