Within the hepatocyte, fatty acids can only be derived from de novo lipogenesis, uptake of nonesterified fatty acid and LDL, or lipolysis of intracellular triacylglycerol. The fatty acid pool may be oxidized for energy or may be combined with glycerol to form mono-, di-, and then triacylglycerols. It is possible that a lower ability to oxidize fat within the hepatocyte could be one of several susceptibility factors for the accumulation of liver fat (45). Excess diacylglycerol has a profound effect on activating protein kinase C epsilon type (PKCε), which inhibits the signaling pathway from the insulin receptor to insulin receptor substrate 1 (IRS-1), the first postreceptor step in intracellular insulin action (46). Thus, under circumstances of chronic energy excess, a raised level of intracellular diacylglycerol specifically prevents normal insulin action, and hepatic glucose production fails to be controlled (Fig. 4). High-fat feeding of rodents brings about raised levels of diacylglycerol, PKCε activation, and insulin resistance. However, if fatty acids are preferentially oxidized rather than esterified to diacylglycerol, then PKCε activation is prevented, and hepatic insulin sensitivity is maintained. The molecular specificity of this mechanism has been confirmed by use of antisense oligonucleotide to PKCε, which prevents hepatic insulin resistance despite raised diacylglycerol levels during high-fat feeding (47). In obese humans, intrahepatic diacylglycerol concentration has been shown to correlate with hepatic insulin sensitivity (48,49). Additionally, the presence of excess fatty acids promotes ceramide synthesis by esterification with sphingosine. Ceramides cause sequestration of Akt2 and activation of gluconeogenic enzymes (Fig. 4), although no relationship with in vivo insulin resistance could be demonstrated in humans (49). However, the described intracellular regulatory roles of diacylglycerol and ceramide are consistent with the in vivo observations of hepatic steatosis and control of hepatic glucose production (20,21).

The book instructs readers on how to use the five essentials of health to achieve a diabetes-free life. Through easy, quick exercises (how does 5 minutes a day sound?); tasty, anti-inflammatory recipes; and many other innovative tips, Dr. Fleckenstein lays out a clear, manageable plan to leave diabetes behind. And ending the struggle with blood sugar is just the start, as this 5-step plan also teaches readers how to shed 5, 10, or even 50 pounds along the way.
Despite these encouraging results, Vulksan cautions that it's too early for diabetic patients to rely on ginseng. Herbs sold in this country are not standardized, he says, so it's difficult to know for certain what you're buying and impossible to ensure consistent dosages. Besides, his study looked only at American ginseng, and he's not certain the results would hold true for the seven other varieties. What's more, researchers haven't conclusively identified ginseng's active ingredients.
It was the same endorsement the first Diabetes Surgery Summit, also organized by Cummings in 2007, had made, but the landscape had changed since then. In addition to more accumulated research, this time, their stance was backed by over 50 international professional organizations, including the American Diabetes Association. And while other medical societies and organizations had long backed surgery as an option for diabetes, the DSS-II guidelines are the first meant to guide clinical practice.
Called ALA for short, this vitamin-like substance neutralizes many types of free radicals. A build-up of free radicals, caused in part by high blood sugar, can lead to nerve damage and other problems. ALA may also help muscle cells take up blood sugar. In a German study, a team of scientists had 40 adults take either an ALA supplement or a placebo. At the end of the four-week study, the ALA group had improved their insulin sensitivity 27 percent. The placebo group showed no improvement. Other studies have shown a decrease in nerve pain, numbness, and burning.
Diabetes is an illness related to elevated blood sugar levels. When you stop releasing and responding to normal amounts of insulin after eating foods with carbohydrates, sugar and fats, you have diabetes. Insulin, a hormone that’s broken down and transported to cells to be used as energy, is released by the pancreas to help with the storage of sugar and fats. But people with diabetes don’t respond to insulin properly, which causes high blood sugar levels and diabetes symptoms.
Type 2 diabetes is the most common form of diabetes, and unlike type 1 diabetes, it usually occurs in people over the age of 40, especially those who are overweight. Type 2 diabetes is caused by insulin resistance, which means that the hormone insulin is being released, but a person doesn’t respond to it appropriately. Type 2 diabetes is a metabolic disorder that’s caused by high blood sugar. The body can keep up for a period of time by producing more insulin, but over time the insulin receptor sites burn out. Eventually, diabetes can affect nearly every system in the body, impacting your energy, digestion, weight, sleep, vision and more. (5)
One easy way to increase your fat content and quit snacking is to begin your meal by eating an avocado. I and others I know have used this trick to easily quit snacking. Avocados protect you from one of the reasons some dietary research wrongly claims that high-fat diets are bad for you: the danger of gorging yourself on delicious, fatty foods. With plain avocados, there is little danger of gorging. Another danger is clogging your arteries and giving yourself heart disease. But it’s been amply shown that the blame for that falls squarely on trans fats, like margarine. If you see any product with the words “partially hydrogenated” or “hydrogenated” in the list of ingredients, put it back, it’s a trans fat. On the other hand, any fat that comes directly from an animal or plant is not a trans fat and can be safely consumed.
