Incretin medications (GLP-1 RAs and dual agonists) are the most effective class of AOMs for older adults, achieving 15-25% weight loss, but require careful titration to manage side effects.
Incretin drugs like Semaglutide and Tirzepatide are currently the most effective weight loss medications for older adults, often resulting in 15-25% body weight loss. They work by mimicking gut hormones to reduce hunger. Doctors usually start with a low dose to minimize side effects like nausea and gradually increase it.
GoodSupportsHIGH confidence
This class of medication was initially developed for glycemic control, yet the emerging generations have demonstrated significant weight loss, even in older adults, ranging from 15% to 25%.
Why this rating
Supported by multiple RCTs (LEADER, SCALE) and clinical guidelines.

- 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
