This is a randomized, controlled, two-phase crossover study will be conducted in adults aged 18-60 years with prediabetes to compare the effects of a CSIR-developed high-protein, low-glycaemic index rice with conventional rice. Phase I will evaluate acute postprandial glucose, insulin, C-peptide, GLP-1, and hunger/satiety responses, while Phase II will assess 72-hour continuous glucose monitoring (CGM) outcomes, including mean glucose and glycaemic variability. Eligible participants will be randomly assigned to receive both rice types in a crossover manner, with each participant serving as their own control. Individuals with diabetes, major systemic illnesses, abnormal liver or renal function, pregnancy, or glucose-lowering medication use will be excluded.
