Obesity is a major global public health problem, and the use of GLP-1 and GLP-1/GIP receptor agonists has emerged as an effective therapeutic strategy for weight management in adults with overweight or obesity. However, concerns have been raised regarding lean mass loss associated with these medications. This integrative literature review aimed to evaluate the effects of GLP-1 and GLP-1/GIP agonists on body composition, with an emphasis on lean mass preservation and the risk of sarcopenia. Six studies published between 2019 and 2025 were included, selected from databases such as PubMed, Embase, Scopus, Web of Science, Cochrane Library, and LILACS. The findings showed that these drugs promoted significant fat loss with relative preservation of lean mass. However, the lack of functional measures limits the assessment of sarcopenia risk. The adoption of complementary strategies, such as physical exercise and nutritional support, is essential to minimize potential adverse effects on skeletal muscle.
