The rising prevalence of type 2 diabetes is attributable, in part, to increased insulin resistance in our population as we get more obese and exercise less. Insulin resistance can be lowered within a few days of beginning a low-calorie diet, even before significant weight reduction occurs (American Diabetes Association, 1998).

Exercise, especially strenuous exercise, lowers insulin resistance, albeit this benefit fades fast (within 5 days) if exercise is discontinued (American Diabetes Association, 1998).
