Chronic exposure of β-cells to triacylglycerol or fatty acids either in vitro or in vivo decreases β-cell capacity to respond to an acute increase in glucose levels (57,58). This concept is far from new (59,60), but the observations of what happens during reversal of diabetes provide a new perspective. β-Cells avidly import fatty acids through the CD36 transporter (24,61) and respond to increased fatty acid supply by storing the excess as triacylglycerol (62). The cellular process of insulin secretion in response to an increase in glucose supply depends on ATP generation by glucose oxidation. However, in the context of an oversupply of fatty acids, such chronic nutrient surfeit prevents further increases in ATP production. Increased fatty acid availability inhibits both pyruvate cycling, which is normally increased during an acute increase in glucose availability, and pyruvate dehydrogenase activity, the major rate-limiting enzyme of glucose oxidation (63). Fatty acids have been shown to inhibit β-cell proliferation in vitro by induction of the cell cycle inhibitors p16 and p18, and this effect is magnified by increased glucose concentration (64). This antiproliferative effect is specifically prevented by small interfering RNA knockdown of the inhibitors. In the Zucker diabetic fatty rat, a genetic model of spontaneous type 2 diabetes, the onset of hyperglycemia is preceded by a rapid increase in pancreatic fat (58). It is particularly noteworthy that the onset of diabetes in this genetic model is completely preventable by restriction of food intake (65), illustrating the interaction between genetic susceptibility and environmental factors.
Researcher Qizhi Tang, PhD, at the University of California, San Francisco, is studying the changes induced in beta cells by the shortage of oxygen and nutrients. Stem cell-derived islets have a low survival rate in the first few days after transplant due to the lack of adequate oxygen and nutrient supplies. However, the American Diabetes Association states, “Evidence suggests that beta cells can be trained to survive oxygen and nutrient shortages that they are exposed to before and after transplantation.”
During digestion, pancreatic beta cells release not only insulin, but in a much smaller amount, the hormone amylin, which helps mediate sharp rises in blood glucose levels following meals. Pramlintide (Symlin) is a new, synthetic form of amylin that may help improve blood glucose control for some type 1 and type 2 diabetic people who use insulin. Pramlintide has few side effects (nausea is the main one) but it adds another set of injections to a diabetic person's daily pharmaceutical routine, as it cannot be mixed in the same syringe with insulin.
We live in a world where prescription medicine is getting more and more expensive as well as controversial. Alternative medicine is gaining momentum and with good reason! The same is true for treatments for diabetes type 2. You have therapies that can reverse diabetes through lifestyle and diet changes, natural supplements that can help stabilize blood sugar levels, and also herbs that lower blood sugar. Not only are these alternative therapies safer, but they are also easier on your pocket, on your body and mind.
A 2012 review of ginseng in animals and human beings found that not only does ginseng reduce insulin resistance, it also lowers HbA1C levels. It’s been used in traditional Chinese medicine for centuries as one of the most potent herbs for blood sugar control. Indian ginseng, also called Ashwagandha, offers fantastic all round benefits. Scientists are also researching the connection between diabetes and Alzhiemer’s. Panax Ginseng is a type of ginseng that is able to help with both diabetes and Alzheimer’s.
Storage of liver fat can only occur when daily calorie intake exceeds expenditure. Sucrose overfeeding for 3 weeks has been shown to cause a 30% increase in liver fat content (37). The associated metabolic stress on hepatocytes was reflected by a simultaneous 30% rise in serum alanine aminotransferase (ALT) levels, and both liver fat and serum ALT returned to normal levels during a subsequent hypocaloric diet. Superimposed upon a positive calorie balance, the extent of portal vein hyperinsulinemia determines how rapidly conversion of excess sugars to fatty acid occurs in the liver. In groups of both obese and nonobese subjects, it was found that those with higher plasma insulin levels have markedly increased rates of hepatic de novo lipogenesis (2,38,39). Conversely, in type 1 diabetes the relatively low insulin concentration in the portal vein (as a consequence of insulin injection into subcutaneous tissue) is associated with subnormal liver fat content (40). Initiation of subcutaneous insulin therapy in type 2 diabetes brings about a decrease in portal insulin delivery by suppression of pancreatic insulin secretion and, hence, a decrease in liver fat (41). Hypocaloric diet (42), physical activity (43), or thiazolidinedione use (23,44) each reduces insulin secretion and decreases liver fat content. Newly synthesized triacylglycerol in the liver will be either oxidized, exported, or stored as hepatic triacylglycerol. Because transport of fatty acid into mitochondria for oxidation is inhibited by the malonyl-CoA produced during de novo lipogenesis, newly synthesized triacylglycerol is preferentially directed toward storage or export. Hence, hepatic fat content and plasma VLDL triacylglycerol levels are increased.
The first thing to understand when it comes to treating diabetes is your blood glucose level, which is the amount of glucose in the blood. Glucose is a sugar that comes from the foods we eat and also is formed and stored inside the body. It's the main source of energy for the cells of the body, and is carried to them through the blood. Glucose gets into the cells with the help of the hormone insulin.
Dr. Fung says he decided to experiment with intermittent fasting because he was frustrated seeing so many diabetic patients with kidney failure. “It occurred to me that fasting was an underutilized therapeutic option for losing weight,” he recalls. “I started doing this five years ago, and a lot of people got incredibly good results – it reversed their diabetes.”
With all of the nutrition information available today about improving blood sugar, it can be a bit daunting to know which information is correct and which is not. It is so important to look to what science-based evidence and research says about the subject. But even more, we need this science to be translated into easy to understand advice so that we can actually incorporate it into our lives and benefit from it. This is the most important factor.
A success story? Perhaps. But experts advise caution. For one thing, because Sweet Eze contains six different ingredients -- and because the severity of diabetes symptoms can fluctuate on their own -- it's hard to say what exactly is responsible for Cottingham's improvement. For another, supplements carry their own risks. Some products don't contain the ingredients listed on their labels. Others come mixed with dangerous -- and unlisted -- ingredients. And scientists are just beginning to verify which ones actually work.
Trick (important): Cut down on sweets, and if you can, cut them out entirely for a couple months. I still eat ice cream about once a week, and know people who are losing weight on this diet while eating ice cream almost every day. But this probably won’t be the case for everyone. Better to severely restrict sweets for the first few months, and then gradually reintroduce.
