Scientists are cautious, and research is continuing, but evidence is growing that the diet can indeed remove the symptoms of type 2 diabetes. The question for researchers, who are now working on identifying the type of diet that can keep diabetes at bay after reversal, is once we've beaten the condition, how do we improve our lifestyle so it doesn't return? Watch this space.
Type 2 diabetes, although influenced by a person’s genes, is largely thought to be brought about by a poor diet and being overweight for prolonged periods of time, particularly at an old age. The pancreas is either unable to produce enough insulin, or the body’s cells simply don’t react to insulin, which leads to dangerously high blood sugar levels.
The three main types of nutrients found in foods are carbohydrates (or carbs), proteins, and fats, which all provide energy in the form of calories. Foods containing carbs cause blood sugar levels to go up the most. Foods that contain mostly protein and/or fat don't affect blood sugar levels as much. Our bodies need all of these nutrients — in different amounts — to function normally.
Fasting plasma glucose concentration depends entirely on the fasting rate of hepatic glucose production and, hence, on its sensitivity to suppression by insulin. Hepatic insulin sensitivity cannot be inferred from observed postprandial change in hepatic glycogen concentration because glucose transport into the hepatocyte is not rate limiting, unlike in muscle, and hyperglycemia itself drives the process of glycogen synthesis irrespective of insulin action. Indeed, postprandial glycogen storage in liver has been shown to be moderately impaired in type 2 diabetes (50) compared with the marked impairment in skeletal muscle (51).
The above two rules are the only dietary rules you need to maintain ideal weight for the rest of your life, assuming you apply common sense and avoid extremes. The diet works by building in regular periods of insulin relief, keeping your body from becoming resistant to insulin. Following these two rules, you will maintain your weight and health by never entering the vicious cycle of increasing insulin resistance.
