The glycemic index measures the speed at which food causes your blood glucose level to rise. It's measured on a scale of 0 to 100, where 50 represents the average response. High-glycemic foods include white bread, pasta, potatoes, rice, and sugary drinks. They all contain lots of simple sugars, which break down into glucose rapidly. This rapid release of energy spikes your blood sugar, causing a sharp increase in hunger.

It's really important to understand two things about low GI foods:

1. You cannot change the glycemic index of a food— meaning you can not lower a high GI food. You can, however, eat a high GI food with other food groups to lower the overall impact on blood sugar levels. At the end of the day, GI of foods is fixed. 
2. How foods are cooked and combined are important when following a low GI diet. Just because is a food has a low glycemic index, does not mean it can be cooked any way and not change the impact on blood sugar. For example, if a sweet potato is boiled, the impact to blood sugar levels is less than if the sweet potato was baked. Knowing how to prepare low glycemic meals will ensure they're balanced and actually support your health and weight goals. (Download our free Starter Kit to help you with this!)
