Military personnel, as an occupational group, are often exposed to stressful and harmful environments that represent a risk factor for disordered eating, with major repercussions on both physical and mental health. This study aims to explore the effectiveness of weight loss interventions and assess the significance of current obesity treatments for these populations. Three online databases (PubMed, PsycInfo, and Web of Science) were screened to identify randomized controlled trials (RCTs) aiming to treat obesity in active-duty military personnel and veterans. Random-effects meta-analyses were conducted for body weight (BW) and body mass index (BMI) values, both longitudinally comparing treatment groups from pre-to-post intervention and cross-sectionally comparing the treatment group to controls at the end of the intervention. A total of 21 studies were included: 16 cross-sectional (BW: n = 15; BMI: n = 12) and 16 longitudinal (BW: n = 15; BMI: n = 12) studies were meta-analyzed, and 5 studies were narratively synthesized. A significant small overall BW and BMI reduction from baseline to post-intervention was observed (BW: g = \u22120.10; p = 0.015; BMI: g = \u22120.32; p &lt; 0.001), together with a decreased BMI (g = \u22120.16; p = 0.001) and nominally lower BW (g = \u22120.08; p = 0.178) in the intervention group compared to controls at the post-intervention time-point. Despite limitations, such as the heterogeneity across the included interventions and the follow-up duration, our findings highlight how current weight loss interventions are effective in terms of BW and BMI reductions in military populations and how a comprehensive approach with multiple therapeutic goals should be taken during the intervention.<\/jats:p>","DOI":"10.3390\/nu15224778","type":"journal-article","created":{"date-parts":[[2023,11,14]],"date-time":"2023-11-14T11:04:32Z","timestamp":1699959872000},"page":"4778","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Randomized Controlled Trials to Treat Obesity in Military Populations: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4715-0749","authenticated-orcid":false,"given":"Davide","family":"Gravina","sequence":"first","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"},{"name":"Department of Clinical and Experimental Medicine, University of Pisa, 56127 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3905-9857","authenticated-orcid":false,"given":"Johanna Louise","family":"Keeler","sequence":"additional","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"},{"name":"South London and Maudsley NHS Foundation Trust, Bethlem Royal Hospital, Monks Orchard Road, Beckenham BR3 3BX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melahat Nur","family":"Akkese","sequence":"additional","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sevgi","family":"Bektas","sequence":"additional","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"},{"name":"Department of Psychology, Hacettepe University, Ankara 06800, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4185-3670","authenticated-orcid":false,"given":"Paula","family":"Fina","sequence":"additional","affiliation":[{"name":"Faculty of Psychology, Sigmund Freud University Vienna, Freudplatz 1, 1020 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles","family":"Tweed","sequence":"additional","affiliation":[{"name":"South London and Maudsley NHS Foundation Trust, Bethlem Royal Hospital, Monks Orchard Road, Beckenham BR3 3BX, UK"},{"name":"Royal Navy Reserve, London WC1N 1NP, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerd-Dieter","family":"Willmund","sequence":"additional","affiliation":[{"name":"Bundeswehr Center for Military Mental Health, Military Hospital Berlin, 13, 10115 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Treasure","sequence":"additional","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"},{"name":"South London and Maudsley NHS Foundation Trust, Bethlem Royal Hospital, Monks Orchard Road, Beckenham BR3 3BX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1209-6073","authenticated-orcid":false,"given":"Hubertus","family":"Himmerich","sequence":"additional","affiliation":[{"name":"Centre for Research in Eating and Weight Disorders, Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College, London SE5 8AF, UK"},{"name":"South London and Maudsley NHS Foundation Trust, Bethlem Royal Hospital, Monks Orchard Road, Beckenham BR3 3BX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,14]]},"reference":[{"key":"ref_1","unstructured":"WHO (2022).
