Also called weight-loss surgery or metabolic surgery, bariatric surgery may help some people with obesity and type 2 diabetes lose a large amount of weight and regain normal blood glucose levels. Some people with diabetes may no longer need their diabetes medicine after bariatric surgery. Whether and for how long blood glucose levels improve seems to vary by the patient, type of weight-loss surgery, and amount of weight the person loses. Other factors include how long someone has had diabetes and whether or not the person uses insulin.1
The accepted view has been that the β-cell dysfunction of established diabetes progresses inexorably (79,82,83), whereas insulin resistance can be modified at least to some extent. However, it is now clear that the β-cell defect, not solely hepatic insulin resistance, may be reversible by weight loss at least early in the course of type 2 diabetes (21,84). The low insulin sensitivity of muscle tissue does not change materially either during the onset of diabetes or during subsequent reversal. Overall, the information on the inhibitory effects of excess fat on β-cell function and apoptosis permits a new understanding of the etiology and time course of type 2 diabetes.
Answer:  In recent years, intermittent fasting has emerged as a novel way of treating patients with type 2 diabetes. There are anecdotal reports of patients who have lost weight, their blood sugar levels have improved significantly, and they no longer need to take their diabetes medications. Their disease appears to be in remission – if not exactly cured.
In addition to their usual diabetes regimen -- a careful diet, regular exercise, and in some cases, medication -- 23 type 2 diabetic patients took either 3 grams of American ginseng or a placebo each day for eight weeks, at which point they switched treatments. The diabetic patients' fasting blood sugar levels dropped about 9% more when they took ginseng compared with when they took the placebo; glycosylated hemoglobin levels between the two groups differed by 4%, with the ginseng group being lower.
2. Biguanides Metformin is the only form of biguanide currently available. While it may promote modest weight loss and a slight decline in LDL, or "bad," cholesterol, side effects may include nausea, diarrhea, and (when other risk factors are present) the harmful buildup of lactic acid. Glucophage, Glumteza, and Riomet are some brand-name types of metformin available for use.
Efforts to cure or stop type 1 diabetes are still in the early stages, and these approaches will also not be suitable for people that have already lost their insulin-producing cells. A solution could be the creation of an “artificial pancreas” — a fully automated system that can measure glucose levels and inject the right amount of insulin into the bloodstream, just like a healthy pancreas would.
You should have no more than three of these “feeding times” per day. The reason limiting the number and duration of your meal times is so important has to do with staying out of the vicious cycle of increasing insulin resistance.
