Summary Background The current obesity pandemic has given rise to associated comorbidities and complications, including type 2 diabetes and metabolic dysfunction‐associated steatotic liver disease (MASLD). During the last decade, certain glucagon‐like peptide 1 receptor agonists (GLP‐1RA), originally developed as antihyperglycemic drugs, also demonstrated efficacy for weight loss. Aims To review shared pathophysiologic features of common metabolic diseases and compare therapeutic strategies to reduce body weight and related complications. Methods We performed an extensive literature research to describe the effects of lifestyle modification, first‐generation anti‐obesity drugs, and GLP‐1RA on weight loss in humans with obesity, type 2 diabetes and MASLD. Results Until recently, treatment of obesity has been limited to lifestyle modification, which offer moderate degree and sustainability of weight loss. The few approved first‐generation anti‐obesity drugs are either limited to short term use or to certain forms of obesity. Some GLP‐1RA significantly decrease caloric intake and body weight. Liraglutide and semaglutide have therefore been approved for treating people with obesity. They also lead to a reduction of hepatic fat content and inflammation in people with biopsy‐confirmed MASLD. Possible limitations comprise adverse effects, treatment adherence and persistence. Conclusion Certain GLP‐1RA are superior to lifestyle modification and first‐generation anti‐obesity drugs in inducing weight loss. They have therefore markedly changed the portfolio of obesity treatment with additional beneficial effects on steatotic liver disease.
