Primary outcomes

  1. Insulin sensitivity as measured by clamp

    Time frame: 45 minutes to 120 minutes post nasal spray

    We will measure insulin sensitivity by hyperinsulinemic euglycemic clamp before and after nasal spray application. We will compare the post-spray insulin sensitivity between the two condition (insulin nasal spray vs placebo nasal spray). Furthermore, we will compare insulin sensitivity before and after nasal insulin application.

Secondary outcomes

  1. Autonomous nervous system activity

    Time frame: 45 to 120 minutes post spray

    Activity of the autonomous nervous system will be estimated by heart rate variability in ECG. We will compare the post-spray autonomous nervous system activity between the two condition (insulin nasal spray vs placebo nasal spray). Furthermore, we will compare autonomous nervous system activity before and after nasal insulin application.
