If the rapid changes in metabolism following bariatric surgery are a consequence of the sudden change in calorie balance, the defects in both insulin secretion and hepatic insulin sensitivity of type 2 diabetes should be correctable by change in diet alone. To test this hypothesis, a group of people with type 2 diabetes were studied before and during a 600 kcal/day diet (21). Within 7 days, liver fat decreased by 30%, becoming similar to that of the control group, and hepatic insulin sensitivity normalized (Fig. 2). The close association between liver fat content and hepatic glucose production had previously been established (20,22,23). Plasma glucose normalized by day 7 of the diet.
Beware of claims that seem too good to be true. Look for scientific-based sources of information. The National Diabetes Information Clearinghouse collects resource information for the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Reference Collection, a service of the National Institutes of Health.

Treatment plans are designed around the pattern of insulin normally supplied by the pancreas throughout the day in someone without diabetes. In general, this involves providing a fairly steady "background" level of insulin to control blood sugar levels between meals and overnight, along with doses of rapid- or short-acting insulin to handle the fast rises in blood sugar that occur with meals.
