GL in a nutshell
GL stands for Glycaemic Load. It’s a unit of measurement that tells you exactly what a particular food will do to your blood sugar. Foods with a high GL have a greater effect on your blood sugar, which isn’t desirable. Foods with a low GL encourage the body to burn fat, which is what we’re aiming for. Keeping your blood sugar balanced is the concept at the heart of the low GL diet – sustainable weight loss will follow.
When your blood sugar level increases, the hormone insulin is released into the bloodstream to remove the glucose (sugar). Some glucose goes to the brain and muscles where it’s used as an energy fuel, but any excess goes to the liver where it’s turned into fat and stored, causing you to gain weight. Insulin is known as the fat-storing hormone.
The glycaemic load (GL) is based on the glycaemic index (GI). Put simply, the glycaemic index of a food tells you whether the carbohydrate in a food is fast or slow releasing (fast is bad, slow is good). What it doesn’t tell you is exactly how much of the food is carbohydrate. Glycaemic load on the other hand tells you both the type and amount of carbohydrate in the food and what that particular carbohydrate does to your blood sugar.
