Hormonal

FDA-approved anti-obesity medications (AOMs) including GLP-1 agonists (semaglutide, liraglutide), dual agonists (tirzepatide), and others (orlistat, phentermine-topiramate) produce significant weight loss (5-15%) when combined with lifestyle interventions, representing a shift from behavioral-only approaches to targeting physiological root causes.

If you have a BMI of 30 or higher (or 27 with health issues), FDA-approved medications like semaglutide or tirzepatide can help you lose 5-15% of your body weight when combined with diet and exercise. These drugs work by targeting the hormones that control hunger and fullness, addressing the biological drivers of obesity that diet and exercise alone often cannot overcome. Consult a doctor to see if you are a candidate.
