| Outcome Measures: |
Primary: Hepatic Glucose Production (Co-primary Outcome), Tritiated glucose infusion during procedures (Baseline and every 30 minutes during procedures) Calculated from plasma(mg/kg-minute). Averaged every 30 minutes., Participants will be followed during the procedures, until all 3 procedures are completed, an average of 1 month | Secondary: Plasma Insulin Concentrations, Baseline and every 15 minutes during procedures (microIU/mL)., Participants will be followed during the procedures, until all 3 procedures are completed, an average of 1 month|Plasma Glucose Concentrations, Measured at baseline and every 5 minutes during the procedures(mg/dL), Averaged over 30 minute intervals during the procedure, Participants will be followed during the procedures, until all 3 procedures are completed, an average of 1 month|Plasma Glucagon Concentrations, Measured at baseline and every 30 minutes during the procedures (pg/mL), Participants will be followed during the procedures, until all 3 procedures are completed, an average of 1 month|Plasma Free Fatty Acid Concentrations, Measured at baseline and every 30 minutes during the procedures (micro mol/L), Participants will be followed during the procedures, until all 3 procedures are completed, an average of 1 month
