Glycemic Index

Also known as: GI

What it actually is

GI is calculated by feeding 50g of digestible carbohydrate of a food to subjects, then measuring blood-sugar response over 2 hours, comparing it to glucose. Foods are classified as low (0–55), medium (56–69), or high (70+). Low-GI foods cause smaller, slower blood-sugar rises — better for diabetes, PCOS, and weight management.

Why it matters for Pakistanis

Pakistani staples vary widely. Whole-wheat roti is medium (62), white rice is high (72), bajra roti is low (54). Choosing low-GI versions of the same foods you already eat changes outcomes without giving anything up.
