Semaglutide (2.4 mg/week) induces significant weight loss (mean -10.09% body weight) and improves cardiometabolic markers (BMI, waist circumference, blood pressure, CRP, lipids) in obese or overweight non-diabetic adults, with efficacy increasing with dose.

For non-diabetic adults with obesity, once-weekly subcutaneous semaglutide (2.4 mg) is a highly effective treatment for weight loss, averaging a 10% reduction in body weight. It also improves blood pressure, inflammation (CRP), and lipid profiles. While gastrointestinal side effects like nausea are common, they are typically transient. The treatment is dose-dependent, with higher doses yielding greater weight loss.

Compared with placebo, semaglutide induced a significant body weight loss (MD: −10.09%; 95% CI: −11.84 to −8.33; p ˂ 0.00001), elicited a larger reduction in body mass index (MD: −3.71 kg/m2; 95% CI: −4.33 to −3.09; p ˂ 0.00001) and waist circumference (MD: −8.28 cm; 95% CI: −9.51 to −7.04; p ˂ 0.00001)... Semaglutide exhibited a positive effect on blood pressure, C-reactive protein, and lipid profiles... The results were stable and reliable with dose-dependence.
