Abstract

Background: The study examined 374 individuals who were candidates for bariatric surgery due to morbid obesity. The primary objective was to explore the significant dietary patterns and their potential correlation with metabolic syndrome (MetS). Methods: Two distinct dietary patterns were determined in this cross-sectional study using principal components analysis: a healthy dietary pattern (HDP) that contains an abundance of fruits, veggies, and lean protein sources, and a western dietary pattern (WDP) that is identified by the intake of processed foods and high-fat items. The odds ratio was estimated using multivariate logistic regression. Results: The findings showed a concerning link between the WDP and a reduced amount of high-density lipoprotein cholesterol (HDL-C), a crucial element of lipid metabolism and cardiovascular health. Conversely, the HDP did not show a significant link with MetS or its components in this cohort of individuals with morbid obesity. Conclusion: These results underscore the potential adverse impact of a Western-style diet on metabolic health parameters, particularly HDL-C levels, in this population. The study highlights the importance of dietary patterns in influencing metabolic outcomes in individuals with morbid obesity and emphasizes that further researches may elucidate the interventions to reduce the risk of MetS in this high-risk group. © 2025
