Long-term use of FDA-approved GLP-1/GIP agonists (tirzepatide and semaglutide) produces significant weight loss and metabolic improvements in real-world populations, though efficacy is lower than in randomized clinical trials due to conservative dosing and adherence issues.

Tirzepatide and semaglutide are highly effective for weight loss in real-world settings, but results vary. Expect that only about 1/3 to 2/5 of users will lose 10% of their body weight, even with long-term use. This is lower than clinical trial promises due to lower real-world doses and adherence. Consistency and appropriate dosing are key.

GoodSupportsHIGH confidence
For both cohorts, F-AOMs generally showed superior weight loss effects than O-AOMs. Tirzepatide and semaglutide were the most effective F-AOMs... Both medications also benefited HDL, LDL, triglyceride, and HbA1c levels... The disparity can be explained as follows. Firstly, the dosages used in real-world clinical settings tend to be more conservative... Thirdly, medication adherence in real-world practice is generally less strict than in RCTs.

Why this rating

Large-scale EHR data (up to 30M patients) provides high statistical power, though it is observational.
