Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mixed meal tolerance test: A high carbohydrate (60g) and fat (20g) meal. Test food will be delivered in both a liquid drink and typical breakfast food. Blood samples (10ml) will be taken from a cannula pre meal and every 15-30 minutes for 2 hours, For the whole day the total volume of blood taken will be 250 ml, this is less than 1 cup and half the volume of a blood donation. This will occur at the clinic rooms at The University of Auckland and administered by the PI.

We will also collect respiratory samples and body composition measures prior to this meal.
