Abstract Obesity is a chronic condition demanding effective treatment strategies, among which pharmacotherapy plays critical role. As glucagon‐like peptide‐1 (GLP‐1) agonist approved by the Food and Drug Administration (FDA) for long‐term weight management in adults with obesity, liraglutide semaglutide have great loss effect through reducing food intake delaying gastric emptying. The emergence of unimolecular polypharmacology, utilizes single molecules to simultaneously target multiple receptors or pathways, marked revolutionary improvement GLP‐1‐based obesity pharmacotherapy. dual tirzepatide activates both GLP‐1 glucose‐dependent insulinotropic polypeptide (GIP) has shown enhanced potency compared conventional mono agonist. Furthermore, emerging data suggests that GLP‐1/glucagon (GCG) agonist, as well GLP‐1/GIP/GCG triple may offer superior efficacy over This review summarizes comprehensive mechanisms underlying pronounced advantages GLP‐1/GIP GLP‐1/GCG reduction obese without type 2 diabetes. A deeper understanding these multitargeting agonists will provide insights their clinical application guide development new drugs treatment.

Obesity is a major global health issue with various metabolic complications. Both bariatric surgery and dieting achieve weight loss improve whole-body metabolism, but vary in their ability to maintain these improvements over time. Adipose tissue skeletal muscle metabolism are crucial regulation, obesity linked mitochondrial dysfunction both tissues. The impact of versus on adipose remains be elucidated. Understanding the molecular pathways that modulate following holds potential for identifying novel therapeutic targets management. This narrative review summarizes current knowledge diet-induced muscle, sheds light respective effects.
