Clinical Trial Summary

The obesity epidemic presents a growing concern in the United States, affecting more than 42% of adults. This epidemic extends its impact to chronic diseases and escalating healthcare expenses. Its reach has even influenced the military, with more than 20% of Soldiers being classified as obese, based on Body Mass Index ≥30 kg/m2. Current preventative and countermeasures have produced limited success, prompting consideration of pharmacotherapy. Within this context, glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as semaglutide, have emerged as a promising treatment for obesity. Semaglutide can induce significant weight loss, primarily through fat reduction. However, questions persist regarding its effects on lean mass, physical performance, bone structure, and how it influences the underlying metabolic and hormonal milieu. Furthermore, no studies have been completed in military personnel, who must exercise regularly. Therefore, the investigators will conduct a single-center, open-label, observational trial. The trial will consist of a 24-week semaglutide treatment period and a non-treated 52-week follow-up period. We will test the feasibility and potential benefits of semaglutide in military populations, with a focus on understanding how semaglutide influences body composition, physical performance, hormones, and metabolism. This research holds military significance as obesity rates among service members continue to rise, undermining their medical readiness. Ultimately, it is important to understand if GLP-1RAs can provide a viable solution to obesity in military personnel and if there might be an unexpected effect on physical readiness due to the nature of the weight loss. This could cut down on healthcare expenses by reducing the reliance on weight-related initiatives and, consequently, lowering military separations.
