resistant starch
Primary outcome measure
Insulin sensitivity will be assessed before and after the 12-week intervention by the following:
1. Euglycaemic-hyperinsulinaemic clamp
2. Liver fat content measured by Magnetic Resonance Imaging [MRI]
Secondary outcome measures
The following outcomes are being measured before and after the 12-week intervention:
1. Endothelial function, assessed by Pulse Wave Velocity (PWV) and 24-hour blood pressure recordings
2. Blood inflammatory markers
