It has been shown numerous times that exercise may prevent certain diseases such as heart disease and diabetes, although the exact mechanism of this effect is often disputed. This study found that one of these mechanisms is that physical activity causes a reduction in insulin resistance.

The authors maintain that insulin resistance definitely plays an important role in the development of diabetes, although they were not able to come to the same conclusion in regards to heart disease. They feel that the majority of the risk reduction for heart disease induced by exercise must be obtained through a different mechanism.

Insulin is the key to the vast majority of chronic illness. Fortunately, it is the variable most easily influenced by healthy eating and exercise. Conventional medicine will prescribe drugs to lower blood sugar in type 2 diabetics and give verbal acknowledgment to exercise.

However, few really encourage it as aggressively as they should. It is an incredibly powerful tool. I am personally appreciative of this tool as without exercise I would be a type 2 diabetic. Running 20 miles a week seems to keep my blood sugar in a nearly ideal range.

When I reduce my miles to five or less, my blood sugar gradually rises to the diabetic range. One does not have to run 20 miles per week, but most diabetics will benefit from one hour of intense exercise at least five times per week, and more if their blood sugar is currently out of control.
