Secondary

MeasureTime frame
Incremental Area Under the Curve (iAUC) for blood glucose and blood glucose levels at each time point from breakfast to before lunch. Satiety and hunger scores measured by Visual Analogue Scale (VAS) Assessment of adverse events and gastrointestinal symptoms (e.g., abdominal bloating, diarrhea) via interviews
