About Glycemic Load Calculator

A food's Glycemic Index and it's Glycemic Load are incredibly important information for those trying to lose weight and for individuals who are trying to maintain a stable blood glucose level.

Unfortunately, finding glycemic information about foods can be difficult, and often the information found will only provide the Glycemic Index of a food. While the Glycemic Index is important, the Glycemic Load is a better indicator of how a food will affect your blood glucose. was created to help everyone find the Glycemic Load of foods quickly and easily.

What is the Glycemic Index?

The Glycemic Index measures how a food will affect blood glucose over time. Measured on a scale of 0 - 100, foods with a lower Glycemic Index are less likely to affect blood glucose levels.

Glycemic Index Scale:

  • 55 or less - Low
  • 56 to 69 - Medium
  • 70 and up - High

How is the Glycemic Index of a food established?

Test subjects consume an amount of food equal to 50 carbohydrates of that food, and their blood glucose is measured for the next several hours to create the Glycemic Index.

What is Glycemic Load?

The Glycemic Index does not take into account the actual number of carbohydrates in a food, which can lead to some odd results. For instance, watermelons have a Glycemic Index of 76, which is quite high. But because watermelons actually contain a low number of carbs per serving, a normal serving of watermelons will not spike you blood glucose as much as the Glycemic Index would seem to indicate.

A food's Glycemic Load takes into account the actual number of net carbohydrates in a food. Despite having a Glycemic Index of 73, a cup of watermelons have a Glycemic Load of only 8 - which is low.

Glycemic Load Scale:

  • 10 or less - Low
  • 11 to 19 - Medium
  • 20 and up - High
