We previously reported that dihydroceramides, a specific type of sphingolipid, are elevated in insulin-resistant individuals; however, little is known regarding whether insulin-sensitizing lifestyle interventions can improve profiles of sphingolipids and other lipid species.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A total of 21 individuals with obesity participated in a 3-month lifestyle intervention of combined weight loss and exercise training. Insulin sensitivity was assessed by hyperinsulinemic-euglycemic clamps, and serum lipidomics was conducted.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Following the intervention, BMI was significantly reduced by 10%; VO<sub>2</sub>peak and insulin sensitivity increased by 12% and 57%, respectively; and total serum triacylglycerol (TAG), diacylglycerol, dihydroceramides, sphingosine-1-phosphate, and sphinganine-1-phosphate were significantly reduced, as were specific species of dihydroceramides (C18:0 and C24:1). Individuals with higher preintervention TAG concentrations had significant decreases in serum lipids, which were not significantly changed in individuals with lower preintervention TAG.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>These data show that serum sphingolipid species previously linked to insulin resistance in humans can be reduced with insulin-sensitizing lifestyle interventions. Furthermore, individuals with elevated serum TAG may significantly benefit from lifestyle interventions that increase insulin sensitivity due to a greater decrease in serum lipids related to insulin resistance.</p>\u0000 </section>\u0000 </div>","PeriodicalId":215,"journal":{"name":"Obesity","volume":"32 12","pages":"2334-2344"},"PeriodicalIF":4.2,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142718089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
