Patients with type 1 diabetes mellitus require direct injection of insulin as their bodies cannot produce enough (or even any) insulin. As of 2010, there is no other clinically available form of insulin administration other than injection for patients with type 1: injection can be done by insulin pump, by jet injector, or any of several forms of hypodermic needle. Non-injective methods of insulin administration have been unattainable as the insulin protein breaks down in the digestive tract. There are several insulin application mechanisms under experimental development as of 2004, including a capsule that passes to the liver and delivers insulin into the bloodstream.[39] There have also been proposed vaccines for type I using glutamic acid decarboxylase (GAD), but these are currently not being tested by the pharmaceutical companies that have sublicensed the patents to them.

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.

Before making any fiber recommendations, Dean has her patients tested for “pancreatic insufficiency.” She believes people with pancreatic insufficiency should be given digestive enzymes along with fiber, “otherwise the fiber will just bloat them up, and they’ll be quite unhappy,” she says. Dean uses a glucomannan fiber supplement for her patients with type 2 diabetes.
Suppose your friend is diagnosed with type 2 diabetes, then works hard to lose 50 pounds. He takes himself off all his medications and his blood sugars are now normal. What would you say to him? Probably something like “Great job. You’re really taking care of yourself. Keep it up!” What you wouldn’t say is something like “You’re such a dirty, filthy liar. My doctor says this is a chronic and progressive disease so you must be lying ”. It seems perfectly obvious that diabetes reversed because your friend lost all that weight. And that’s the point. The disease is reversible.
