Consequently, the aim of this study was to identify dietary patterns (DPs) in bariatric surgery candidates, as well as to assess the relationship between DPs, degree of obesity, and body composition. Methods: The participants were comprised of 117 bariatric surgery candidates. Data concerning their diet, lifestyle, and socioeconomic status was collected using the KomPAN\u00ae questionnaire. The following three DPs were identified using a principal component analysis: \u2018Sandwiches &amp; Sweets\u2019, \u2018Fast Food, Convenience Food &amp; Alcohol\u2019 and \u2018Prudent\u2019. Baseline nutritional status and body composition using electric bioimpedance were assessed. Results: Differences were found between the DPs, degree of obesity, and body composition. The Prudent DP primarily involved a high consumption of healthy products. Following the Prudent DP, differentiated the degree of obesity and the patient\u2019s body composition the most. In turn, the Fast Food, Convenience Food &amp; Alcohol DP was associated with a higher likelihood of Degree III obesity and a very high visceral fat level (VFL). The Sandwiches &amp; Sweets DP included the most participants with a very high VFL. Conclusions: The bariatric surgery candidates were shown to follow different diets, and different DPs could be identified. Patients with a higher degree of obesity followed a more beneficial DP, which was likely due to their higher awareness of the risks of morbidity in obesity and of post-surgical complications. Socioeconomic factors may attenuate the association between diet and the degree of obesity and body composition in bariatric surgery candidates.<\/jats:p>","DOI":"10.3390\/nu17040716","type":"journal-article","created":{"date-parts":[[2025,2,18]],"date-time":"2025-02-18T08:36:19Z","timestamp":1739867779000},"page":"716","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Dietary Patterns and Nutritional Status in Bariatric Surgery Candidates\u2014A Cross-Sectional Study"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4246-6944","authenticated-orcid":false,"given":"Kamila","family":"Sobas","sequence":"first","affiliation":[{"name":"Institute of Health Sciences, Collegium Medicum, Jan Kochanowski University, 25-369 Kielce, Poland"},{"name":"Dietary Clinic Meduniv sp. zo.o. in Kielce, 25-369 Kielce, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3063-0380","authenticated-orcid":false,"given":"Edyta","family":"Suliga","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, Collegium Medicum, Jan Kochanowski University, 25-369 Kielce, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3407-7079","authenticated-orcid":false,"given":"Piotr","family":"Bryk","sequence":"additional","affiliation":[{"name":"Institute of Medical Sciences, Collegium Medicum, Jan Kochanowski University, 25-369 Kielce, Poland"},{"name":"Clinic of General, Oncological and Endocrinological Surgery, Provincial Hospital in Kielce, 25-736 Kielce, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7752-0459","authenticated-orcid":false,"given":"Stanislaw","family":"Gluszek","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, Holy Cross Cancer Centre in Kielce, 25-734 Kielce, Poland"},{"name":"Department of Surgery, Hospital of the Ministry of Interior and Administration in Kielce, 25-375 Kielce, Poland"},{"name":"Institute of Genetics and Animal Biotechnology, Polish Academy of Sciences, 05-552 Magdalenka, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Candio, P., Mujica, F.P., and Frew, E.
