Antiobesity medications (AOMs), particularly GLP-1/GIP receptor agonists like semaglutide and tirzepatide, are effective adjuncts to lifestyle modifications for achieving clinically significant weight loss (>5-10% total body weight) in patients with BMI >30 (or >27 with comorbidities).

If you have a BMI over 30 (or 27 with health issues), lifestyle changes alone may not be enough for lasting results. Talk to your doctor about GLP-1/GIP medications like semaglutide or tirzepatide. These are weekly injections that help with appetite and satiety. They work best when combined with diet and exercise changes, and your doctor should monitor your nutrition to prevent deficiencies.

GoodSupportsHIGH confidence
In many patients, antiobesity medications (AOMs) play a role in sustainable intervention and are appropriate in patients with a BMI >30 or >27 with weight-related comorbidities... The newest and currently most efficacious AOMs are semaglutide and tirzepatide, which are long-acting GLP-1/GIP receptor agonists... Older classes of medications result in an average of 5%–10% TBW loss, and newer classes result in an average of 10%–20% TBW.
