Although the promises are big, these technologies are still far from the market. First, clinical trials will have to show they do work. Then, the price could be steep, as cell therapy precedents for other applications, such as oncology, come with price tags that reach the six figures and are finding difficulties to get reimbursed. Considering that compared to cancer, diabetes is not an immediately life-threatening disease, health insurers in some countries might be reluctant to cover the treatment.
If you have type 2 diabetes, sometimes eating healthy and engaging in physical activity is not enough. Your doctor may give you oral medication to help control your blood glucose levels. For people with type 1 diabetes (and some people with type 2 diabetes) this means taking insulin. People with type 1 diabetes must take insulin to control diabetes--and this can only be done through multiple injections or by an insulin pump, a small device that delivers insulin continuously throughout the day.

However, the observation that normalization of glucose in type 2 diabetes occurred within days after bariatric surgery, before substantial weight loss (15), led to the widespread belief that surgery itself brought about specific changes mediated through incretin hormone secretion (16,17). This reasoning overlooked the major change that follows bariatric surgery: an acute, profound decrease in calorie intake. Typically, those undergoing bariatric surgery have a mean body weight of ∼150 kg (15) and would therefore require a daily calorie intake of ∼13.4 MJ/day (3,200 kcal/day) for weight maintenance (18). This intake decreases precipitously at the time of surgery. The sudden reversal of traffic into fat stores brings about a profound change in intracellular concentration of fat metabolites. It is known that under hypocaloric conditions, fat is mobilized first from the liver and other ectopic sites rather than from visceral or subcutaneous fat stores (19). This process has been studied in detail during more moderate calorie restriction in type 2 diabetes over 8 weeks (20). Fasting plasma glucose was shown to be improved because of an 81% decrease in liver fat content and normalization of hepatic insulin sensitivity with no change in the insulin resistance of muscle.
Gestational diabetes develops during pregnancy because hormones interfere with how the body uses insulin. When the pancreas can’t keep up with the insulin demand and blood glucose levels get too high, the result is gestational diabetes. About 2-7 percent of expectant mothers develop gestational diabetes during their pregnancy. Learn more about diabetes and pregnancy.
The extent of weight loss required to reverse type 2 diabetes is much greater than conventionally advised. A clear distinction must be made between weight loss that improves glucose control but leaves blood glucose levels abnormal and weight loss of sufficient degree to normalize pancreatic function. The Belfast diet study provides an example of moderate weight loss leading to reasonably controlled, yet persistent diabetes. This study showed that a mean weight loss of 11 kg decreased fasting blood glucose levels from 10.4 to 7.0 mmol/L but that this abnormal level presaged the all-too-familiar deterioration of control (87).
A couple of studies have found that cinnamon improves blood glucose control in people with type 2 diabetes. In the first study, 60 people with type 2 diabetes were divided into six groups. Three groups took 1, 3 or 6 g of cinnamon a day and the remaining three groups consumed 1, 3 or 6 g of placebo capsules. After 40 days, all three doses of cinnamon significantly reduced fasting blood glucose, triglycerides, LDL cholesterol, and total cholesterol.
Genetic factors do play a role in any disease, but I put this factor last for a reason. Genetic predisposition to a given disease will increase the chances of getting the disease, but not in a vacuum. People with a strong predisposition to liver disease manage to avoid it, and some with a family history of heart disease remain heart-attack free. Even studies among identical twins show that in most cases, twins will get the same diseases, even in different environments, but sometimes they don’t. This means there are other factors involved (see above).
Yet Gabbay says preliminary human studies with positive results, like this week’s in BMJ Case Reports, suggest the diet is worthy of further study in a larger population over a longer period of time. For now, he cautions people with diabetes, especially those on insulin and sulfonylureas to lower their blood sugar, against trying intermittent fasting before speaking with their healthcare provider.
Like the sulfonylureas, meglitinides is a class of drugs that work by promoting insulin secretion from the pancreas. Unlike the sulfonylureas, which last longer in the body, repaglinide (Prandin) and nateglinide (Starlix) are very short acting, with peak effects within one hour. For this reason, they are given up to three times a day just before meals.
