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.
Other research conducted at the same institute studied possible regeneration of the islets of langerhans in rats that were made diabetic for the study and then given gymnema sylvestre leaf extracts. The diabetic rats were able to double the number of their islets and beta cell numbers. Researchers felt that the herbal therapy was able to bring blood sugar stability by repairing the pancreas and increasing insulin secretion.
I made a mistake in an earlier comment that I need to correct. I thought the VLDL represented the very small particles, and that is totally wrong. Here are the actual test results of the very small particles from a Quest Diagnostics after about 18 months on a ketogenic diet, with abundant use of MCT oil as caprylic acid. If the administrator deletes that comment, to avoid confusion, that would be fine with me. I can also provide much more data, as that test is pretty comprehensive.
Peripheral neuropathy is a problem with the functioning of the nerves outside of the spinal cord. Symptoms may include numbness, weakness, burning pain (especially at night), and loss of reflexes. Possible causes may include carpel tunnel syndrome, shingles, vitamin or nutritional deficiencies, and illnesses like diabetes, syphilis, AIDS, and kidney failure. Peripheral neuropathy is diagnosed with exams and tests. Treatment for the condition depends on the cause. Usually, the prognosis for peripheral neuropathy is good if the cause can be successfully treated or prevented.
When a patient is ready to make a big commitment to get their blood sugar under control, Simos works with them to help tease apart what may be causing their blood sugar to spiral. Sometimes it’s what they're eating, sometimes it’s stress at home and at work and sometimes it’s a day full of sitting versus moving. Often, it’s a mix of these things. Other factors may contribute to diabetes risk, including a family history of the disease.
Exenatide (Byetta) was the first drug of the GLP-1 agonist group. It originated from an interesting source, the saliva of the Gila monster. Scientists observed that this small lizard could go a long time without eating. They discovered a substance in its saliva that slowed stomach emptying, thus making the lizard feel fuller for a longer time. This substance resembled the hormone GLP-1.
“High glycemic index foods are going to be primarily processed foods,” says Lori Chong, RD, CDE, at The Ohio State University Wexner Medical Center in Columbus. Those processed foods tend to have more white sugar and flour in them, which are higher on the GI, she says. Foods lower on the GI include vegetables, especially non-starchy vegetables, like broccoli, cauliflower, and leafy greens and whole-grain products, such as brown rice (as opposed to white rice), Chong says. She notes that even many fruits are low on the GI, with pineapple and dried fruit being some of the highest (Berries, apples, and pears tend to be fairly low.)
