4 Discussion Current evidence strongly supports the efficacy of GLP-1 receptor agonists for inducing substantial weight loss, improving metabolic control, and reducing cardiovascular risk often surpassing the short-term effects of exercise alone ( Exercise and lifestyle interventions, while generally less potent for weight loss, provide unique and irreplaceable health benefits preserving skeletal muscle, improving cardiorespiratory fitness, enhancing psychological well-being, and lowering chronic disease risk ( Hybrid care models that integrate pharmacotherapy with behavioral support are emerging as the most promising framework for sustainable obesity and diabetes management ( Persistent challenges include the high cost and limited accessibility of GLP-1RAs, variable long-term adherence, and a lack of long-term data on sustainability, relapse rates, and overall health outcomes

In this Review, we summarize current preclinical and clinical evidence, showing that the riskbenefit profile of GLP1RAs remains favourable in individuals with T2DM and obesity, although caution is warranted in those with a low cardiometabolic risk, for whom the potential risks of cancer might outweigh any expected benefits
Most users begin noticing skin firmness improvements within 4 to 8 weeks of consistent subcutaneous administration, with optimal results typically appearing after 12 weeks of use
