This is part 8 of my review in Layman's terms of the book 'The Art and Science of Low carbohydrate Living' By Jeff S. Volek, PhD, RD & Stephen D. Phinney, MD, PhD
Insulin was discovered in 1922 and insulin resistance in about 1930, and nearing 100 years later the complete understanding of why the resistance happens is still debated. The reason there is an entire chapter on insulin resistance is its prevalence with a low carb diet. Low carb from short to long term improves, without any doubt to improve insulin sensitivity. With studies done over the years experts have focused on a low carb, high fat diet being 45-60%fat of energy , and that is why the insulin sensitivity only improves in some. By upping the fat to 65-85% this would be going into nutritional ketosis has much better results (more on this in chapter 12)
The Biology of Insulin Resistance Remains Unknown
The problem in science is when the 'reductionist' approach is used (only looking in the singular). This is modern science , isolating each individual factor and just looking at that, not considering if two factors next to each other might be the problem. Insulin resistance is not likely due to be one dysfunctional protein but rather a number of them. a more holistic approach is more likely to fine the problem with looking at each individual person as a whole and breaking down what is going wrong with the combination of things going on in the body.
Carbohydrate Increases Insulin
Insulin' (a hormone) is released from the pancreas by its primary stimulator ' carbohydrate', where as fat being used as energy has virtually no effect on the pancreas (no need for insulin to be released). Elevated blood sugar (hyperglycemia) is when eating a carbohydrate meal , which turns into glucose via liver into the blood, your pancreas releases insulin to store the glucose in cells, buttttttt, the insulin is not opening the cells to let glucose in or out for energy or storage. Think of insulin as the key to open the cells (the key hole,) . So by looking at insulin resistance as literally carbohydrate intolerance , the carbohydrates become the burden on the system and in the long term dysfunction of normal body functions. Insulin is also the key to let fat out of the cells , so if there is high insulin in the blood stream and the cells aren't recognizing the key, fat is not released, you can not loose weight.
How is Insulin Resistance Measured?
There are a number o f ways to measur
