Glycemic Load (Indian Foods)
GL = (carbs × GI) / 100. GL ≤ 10 = low, 11-19 = medium, ≥ 20 = high. Manage portions to stay in the low-medium band.
- ≤ 10 — Low
- 11–19 — Medium
- ≥ 20 — High
Why GL beats GI
The Glycemic Index (GI) tells you how fast 50 g of carbs from a food spikes blood sugar. But you rarely eat 50 g — a watermelon slice has GI 76 but only ~6 g carbs. GL = GI × carbs per serving / 100 adjusts for portion. A 2 kg watermelon slice and a small puri have similar GL despite very different GIs.
Worked example: typical Indian meals
A south-Indian thali — 2 idli (GL 14) + sambar (GL 6) + rice 100g (GL 26) + papad — totals GL ~50, a high-GL meal that spikes sugar by 80–120 mg/dL post-prandial. Swap rice for 2 chapatis (GL 14) and the same plate drops to GL ~38. Add a small bowl of curd (GL 3, slows absorption) and post-meal spike drops another ~20 mg/dL. The arithmetic is why Indian diabetics are told “reduce rice, add protein”.
When to use this
- Type 2 diabetic planning low-GL meals (HbA1c > 6.5%)
- PCOS / insulin resistance — keep meal GL under 20
- Pregnant woman with gestational diabetes
- Anyone scoring high on the Indian Diabetes Risk Score wanting to delay onset

FAQ
Why does GL matter more than GI?
GI ignores portion size. A spoon of jaggery (high GI) raises blood sugar less than a katori of basmati rice (lower GI but bigger portion). GL multiplies GI by carbs, giving the actual blood-sugar impact.
Can low-GL meals reverse pre-diabetes?
In studies, yes — switching from refined carbs (white rice / maida) to whole grains (jowar / bajra / brown rice) lowers fasting glucose and HbA1c within 3-6 months for most pre-diabetics.
Are sweet fruits like mango bad for diabetics?
In moderation, no. Mango GL is ~14 (medium) — 1 medium fruit is fine if not eaten with rice and sweets. Pair with protein/fat to slow absorption further.
