Sugar, in the form of glucose, is the main source of fuel for body cells, and the hormone insulin allows glucose in the blood to enter those cells. In type 2 diabetes, genetic or lifestyle factors have resulted in a decrease in the body's ability to efficiently metabolize your sugar (glucose). This could mean that your body may no longer produce enough insulin, or that your cells are becoming more resistant to the effects of insulin, and too much glucose is starting to build up in your bloodstream.Sugar Balance
