BACKGROUND: Protein glycosylation is an enzymatic process known to reflect an individual's physiologic state and changes thereof. The impact of metabolic interventions on plasma protein N-glycosylation has only been sparsely investigated. OBJECTIVE: To examine alterations in plasma protein N-glycosylation following changes in caloric intake and bariatric surgery. SETTING: University of Texas Southwestern Medical Center, US and Oxford University Hospitals, UK. METHODS: This study included 2 independent patient cohorts that recruited 10 and 37 individuals with obesity undergoing a period of caloric restriction followed by bariatric surgery. In both cohorts, clinical data were collated, and the composition of plasma protein N-glycome was analyzed chromatographically. Linear mixed models adjusting for age, sex, and multiple testing (false discovery rate
