It is important to understand blood sugar levels in order to control hunger, maintain a healthy weight, and prevent insulin resistance and type 2 diabetes.

Glucose is the primary source of energy in the body. It is transported from the intestines or liver through the bloodstream, where the hormone insulin allows it to be absorbed by cells.

After you eat carbohydrates, the amount of sugar in your blood stream is paralleled by a rise in insulin, which allows your muscles and other cells to soak up the glucose and put it to work.  When you eat foods loaded with fast-acting carbohydrates from refined grains or sugars, the resulting load of insulin sends glucose levels plummeting, causing feelings of hunger.

 

On the other hand, meals containing large amounts of fiber and protein and fewer carbohydrates are more slowly digested, preventing these spikes in blood sugar and insulin levels.

The Glycemic Index measures how certain carbohydrates affect our blood sugar.
