GLP-1 receptor agonists (liraglutide, semaglutide) and dual GLP-1/GIP agonists (tirzepatide) are the most promising pharmacological treatments for obesity in older adults, offering favorable efficacy and safety profiles, though specific guidelines are currently lacking.
For older adults with obesity, GLP-1 agonists like liraglutide and semaglutide are currently the most effective pharmacological options. They work by mimicking hormones that regulate appetite and blood sugar. While they cause significant weight loss, there is a risk of muscle loss, so these medications should ideally be used alongside resistance exercise and adequate protein intake. Start with a low dose and increase slowly to manage stomach side effects. Note that data for those over 75 is limited.
From currently available obesity pharmacotherapy, GLP-1 agonist (or combined GLP-1 and GIP agonist) data offer the most promising weight loss, body composition and safety outcomes in older adults; however, more research on muscle/bone mass preservation is needed.
Why this rating
Based on post-hoc analyses of large trials (SCALE, SUSTAIN, LEADER) and small specific trials, but lacking dedicated large-scale RCTs for >65s.

- 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
