Abstract Obesity has emerged as a global health crisis requiring innovative therapeutic strategies beyond conventional approaches. While glucagon‐like peptide‐1 (GLP‐1) and dual GIP/GLP‐1 receptor agonists have redefined pharmacological management, their limitations necessitate further innovation. Retatrutide (LY3437943), a novel triple agonist targeting GLP‐1, glucose‐dependent insulinotropic polypeptide (GIP), and glucagon receptors, represents a transformative advance in obesity pharmacotherapy. Phase 2 trials report unprecedented weight reductions, comparable to bariatric surgery, with additional benefits for metabolic comorbidities such as NASH and cardiovascular disease. Retatrutide exemplifies rational multi‐agonist peptide engineering and signals a paradigm shift in systems pharmacology. This perspective underscores the urgent need for scientific engagement, equity considerations, and policy preparedness, positioning retatrutide as a watershed in obesity treatment and a blueprint for future poly‐agonist therapies.
