Arms of the Study
Arm 1
Arm 2
Active Comparator
Experimental
standard dietary intervention (SDI) arm
LGI intervention arm
The general principles for the SDI arm are to provide an understanding of carbohydrates, be isocaloric based on assessment from the food diary/ recall and anthropometric measures, provide a personalised even distribution of carbohydrate throughout the day, have general recommendations such as reduction of fat, sodium, sugar and an increase in fibre
The general principles for the LGI intervention arm include the SDI principles and instructions on GI, identifying foods of different GI, switching to low GI food and having at least one low GI food per meal and suggested meals with recipes. Participants will also have the opportunity to attend sessions to learn how to cook meals with low GI. Participants will be provided with a list of low GI carbohydrates to consume during the intervention period and in addition, they will be provided with a supply of the staples for the same period
