Diabetics tend to have reduced insulin secretion response or even an insulin resistance. This means that their body’s ability to use insulin properly is impaired. In someone without diabetes beta cells sense the rising of blood glucose levels and secrete insulin into the blood. The insulin then allows the sugar to be used by the cells for energy. The result of this is that the glucose levels return to normal, and insulin secretion is reduced. In diabetics, however the cells do not respond to the insulin that is being released, and therefore releases more insulin.

A study was recently performed on reduced insulin secretion in type-2 diabetes. The subjects were the Pima Indians of Arizona because the prevalence and incidence rates of this group are the highest in the world. Studies have shown that glucose tolerance deteriorates as obesity increases due to worsening insulin resistance and decreases in early insulin …
