title: The effect of ten days of fasting on various aspects of carbohydrate metabolism in obese diabetic subjects with significant fasting hyperglycemia.
abstract: Patients with nonketotic diabetes mellitus, who were both obese and had significant fasting hyperglycemia (mean plasma glucose = 310 mg/100 ml), were fasted for 10 days. There was a prompt drop of plasma glucose levels as the result of the caloric deprivation with a mean fall of approximately 200 mg/dl at the end of the fast. The drop in plasma glucose level that occurred during the fast was associated with a drop in plasma insulin level. Fasting plasma glucose concentration rose immediately after food intake was resumed and stabilized within 3--4 days at levels halfway between the initial and the lowest value. At this time, the patients also seemed capable of disposing of an oral glucose load more efficiently. The apparent improvement in carbohydrate homeostasis observed after the fast could not be attributed to an increase in insulin response, but was associated with some amelioration of the insulin resistance that characterizes these patients. Unfortunately, the beneficial effects of the 10-day period of caloric deprivation were transitory and fasting plasma glucose values had returned to prefast levels in most patients within a few months.
