Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Double blind cross-over single dose study.

The intervention is exenatide, 2.5 micrograms, subcutaneously administered 15 minutes prior to the commencement of a pancake meal.

Exenatide is a clear fluid, identical to the placebo (0.9% normal saline).

There will be 2 study days with at least 2 days between start times.

The medication will be administered on the study day by the researcher. The pancake will be prepared and provided on the study day by the researcher.

Treatment: Drugs
Comparator / control treatment
Placebo will contain 0.9% normal saline in the same volume as the intervention.
Control group
Placebo
