As part of the Glucose Monitoring Workshop earlier in the semester, students collected blood glucose data after consuming a high-GI meal (pizza) following a 2-hour fast. This was compared to data from a previous cohort who had fasted overnight before consuming either a high- or low-GI breakfast.

1. Describe the key differences observed in the magnitude and timing of the glucose peaks between the high-GI meals. (2 marks)

2. Identify and explain two physiological or experimental factors that could account for these differences. (4 marks)

3. Explain how differences in fasting duration and study design might influence clinical decision-making. (4 marks)
