Carbohydrate and lipid oxidation rates and nonoxidative glucose storage and during basal conditions, low insulin infusion (0.5 mU/kg LBM/min), and high insulin infusion (1 mU/kg LBM/min) during a hyperinsulinemic euglycemic clamp. Data are expressed as . Abbreviations: CTS: control subjects; RYGB: Roux-en-Y gastric bypass group; SG: sleeve gastrectomy group; pre: preoperatively; post: postoperatively; CHOX: carbohydrate oxidation; LIOX: lipid oxidation; Non-ox glucose storage: nonoxidative glucose storage; LBM: lean body mass.
