Digital tools may enhance adherence to nutritional strategies, but their impact on detailed body composition remains insufficiently explored. Methods: This 6-month prospective controlled longitudinal intervention study included 60 middle-aged and older adults. All participants received a smart watch and smart scale for self-monitoring. The control group attended evaluations only at baseline and study completion, while the intervention group received monthly follow-up and remote feedback. Body composition was assessed using multi-frequency BIA. Statistical analyses included paired tests, effect sizes, correlations, and linear mixed-effects models. Results: Significant reductions were observed in BMI (p &lt; 0.001), fat mass (p = 0.003), and visceral fat (p = 0.003; Cohen\u2019s d = 0.41). The sarcopenic index improved (p = 0.001), while skeletal muscle mass remained stable. ECW increased significantly (p = 0.010). Age was inversely associated with the magnitude of improvement. Mixed-effects modeling confirmed a time-dependent reduction in visceral fat independent of age and sex. Conclusions: A 6-month digitally assisted nutritional monitoring program was associated with favorable changes in adiposity, muscle quality, and hydration status. Multi-frequency BIA provides valuable integrative markers for monitoring nutritional interventions in aging populations.<\/jats:p>","DOI":"10.3390\/nu18071140","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T14:59:01Z","timestamp":1775055541000},"page":"1140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Digital-Assisted Nutritional Monitoring and Body Composition Changes in Aging Adults: A 6-Month Controlled Longitudinal Study"],"prefix":"10.3390","volume":"18","author":[{"given":"Rare\u0219 Gheorghe","family":"Mihu\u021b","sequence":"first","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8981-1958","authenticated-orcid":false,"given":"Timea Claudia","family":"Ghitea","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Faculty of Medicine and Pharmacy, University of Oradea, 410073 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Morenci","sequence":"additional","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6485-7180","authenticated-orcid":false,"given":"Carmen Delia Cseppento","family":"Nistor","sequence":"additional","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"},{"name":"Department of Psycho-Neuroscience and Recovery, Faculty of Medicine and Pharmacy, University of Oradea, 410073 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Tirla","sequence":"additional","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"},{"name":"Department of Psycho-Neuroscience and Recovery, Faculty of Medicine and Pharmacy, University of Oradea, 410073 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0135-6861","authenticated-orcid":false,"given":"Diana Carina","family":"Iovanovici","sequence":"additional","affiliation":[{"name":"Timi\u0219oara Institute of Cardiovascular Diseases, 300310 Timi\u0219oara, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anett","family":"Karetka","sequence":"additional","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"},{"name":"Department of Pharmacy, Faculty of Medicine and Pharmacy, University of Oradea, 410073 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9778-4187","authenticated-orcid":false,"given":"Akos","family":"Tiboldi","sequence":"additional","affiliation":[{"name":"Ludwig Boltzmann Institute for Traumatology, The Research Center in Cooperation with AUVA, 1200 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00e9ka","family":"Kov\u00e1cs","sequence":"additional","affiliation":[{"name":"Semmelweis University Health Services Management Training Centre, 1125 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5591-7826","authenticated-orcid":false,"given":"T\u00fcnde","family":"Jurca","sequence":"additional","affiliation":[{"name":"Doctoral School of Biomedical Sciences, Faculty of Medicine and Pharmacy, University of Oradea, 410087 Oradea, Romania"},{"name":"Department of Pharmacy, Faculty of Medicine and Pharmacy, University of Oradea, 410073 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Abad-Jim\u00e9nez, Z., and Vezza, T.
