What Is a Low Glycemic Index Diet?

A low glycemic index diet (GI diet) is a low-carbohydrate diet used to treat children who have epilepsy. The treatment was developed in 2002 as a less strict alternative to the ketogenic diet.

A low glycemic diet measures a food item by how much it raises a child’s blood glucose level. That measurement is called its glycemic index. The GI diet favors foods that have only a small effect on blood glucose levels. Such low glycemic index foods include meats, cheeses and vegetables.

Children who follow a GI diet may safely eat certain carbohydrates that have a low glycemic index. However, they should pair the carbohydrates with fats and proteins. For example, eating a piece of whole-wheat toast (high in carbohydrates) along with peanut butter (high in fat and protein) can further lower the glycemic index of the snack.

Who Benefits From a Low Glycemic Index Diet?

Children who have limited success with antiepileptic drugs might be candidates for the GI diet. Additionally, kids who have safely reduced their seizures on the ketogenic diet for two to three years might be able to move to the less strict low glycemic index diet.

What to Expect With a Low Glycemic Index Diet

Before beginning a GI diet, it’s important for your child to have a thorough physical evaluation to determine if they’re a good fit for the diet.

If your child starts following a low glycemic diet, follow-up visits usually happen every six to 12 months to check nutritional balance and seizure control.

How a Low Glycemic Index Diet Helps

Kids who maintain good seizure control on a GI diet will have more flexibility than those following the ketogenic diet. Benefits of the low glycemic diet include:

  • Flexibility: The GI diet allows a wider variety of foods than the ketogenic diet. Portion sizes can be approximated, as opposed to carefully weighed and measured.
  • Convenience: Families can easily work the diet into their mealtime routines.
  • Lifelong value: The diet works well for lifelong nutrition.
