Adherence
Early response to treatment (≥5% weight loss in 3 months) is a strong predictor of long-term success; non-responders should switch therapies.
Monitor your weight closely in the first 3 months of starting a new obesity medication. If you haven't lost at least 5% of your body weight, talk to your doctor about switching to a different therapy. Early success is the best predictor of long-term success.
GoodQualifiesHIGH confidence
Substantial weight loss during the initial phase of treatment correlates with greater weight loss after 12 months, while minimal early weight loss signals a poor likelihood of response over time (34, 41, 42).

- Dual GLP-1/GIP receptor agonists (e.g., tirzepatide) achieve weight loss magnitudes (15-20%) comparable to bariatric surgery, significantly outperforming older pharmacotherapies and single-agonist GLP-1s.Good
- Combining pharmacotherapy with lifestyle interventions (diet/exercise) or bariatric surgery yields superior weight loss and maintenance compared to either intervention alone.Moderate
