This page lists 511 foods related to Ultra Low Calorie Foods (<30 kcal), each with its glycemic load (GL), glycemic index (GI), and a color-coded verdict. Of these, 510 fall in the low-GL range (≤10), 0 are moderate (11–19), and 1 are high (≥20). The average GL per 100g across the group is about 2. GL combines the speed of carbohydrate absorption with the amount you actually eat, which is why it is the more practical number for meal planning than GI alone.
