Conventional: A dietary pattern that includes carbohydrates from fruits, vegetables, whole grains, legumes, and low-fat milk is encouraged for good health. Carbohydrate intake should be monitored using carbohydrate counting or experienced-based estimation. The Recommended Dietary Allowance for digestible carbohydrates is 130 g/day, which will provide a sufficient amount of glucose needed to fuel the central nervous system without reliance on glucose production from protein or fat. Using foods with a low glycemic index that are rich in fiber and other important nutrients is encouraged.
However, the observation that normalization of glucose in type 2 diabetes occurred within days after bariatric surgery, before substantial weight loss (15), led to the widespread belief that surgery itself brought about specific changes mediated through incretin hormone secretion (16,17). This reasoning overlooked the major change that follows bariatric surgery: an acute, profound decrease in calorie intake. Typically, those undergoing bariatric surgery have a mean body weight of ∼150 kg (15) and would therefore require a daily calorie intake of ∼13.4 MJ/day (3,200 kcal/day) for weight maintenance (18). This intake decreases precipitously at the time of surgery. The sudden reversal of traffic into fat stores brings about a profound change in intracellular concentration of fat metabolites. It is known that under hypocaloric conditions, fat is mobilized first from the liver and other ectopic sites rather than from visceral or subcutaneous fat stores (19). This process has been studied in detail during more moderate calorie restriction in type 2 diabetes over 8 weeks (20). Fasting plasma glucose was shown to be improved because of an 81% decrease in liver fat content and normalization of hepatic insulin sensitivity with no change in the insulin resistance of muscle.
A good multiple vitamin and mineral product (or “multiple,” for short) is a great way to start supporting nutrient intake in all diabetic patients. This ensures every day that the body receives all the key nutrients it needs so that all its biochemical, hormonal, nutritional, detoxifying, healing, rebuilding, protecting, and strengthening processes can be performed easily and smoothly. The body runs on enzymes, as enzymes speed up reactions to make the body function more efficiently; all enzymes require nutrient cofactors to enable them to effectively engage the action they are designed to do. A good multiple vitamin supplement for diabetes ensures all those cofactors are available every minute, every day.
Whole-body insulin resistance is the earliest predictor of type 2 diabetes onset, and this mainly reflects muscle insulin resistance (26). However, careful separation of the contributions of muscle and liver have shown that early improvement in control of fasting plasma glucose level is associated only with improvement in liver insulin sensitivity (20,21). It is clear that the resumption of normal or near-normal diurnal blood glucose control does not require improvement in muscle insulin sensitivity. Although this finding may at first appear surprising, it is supported by a wide range of earlier observations. Mice totally lacking in skeletal muscle insulin receptors do not develop diabetes (27). Humans who have the PPP1R3A genetic variant of muscle glycogen synthase cannot store glycogen in muscle after meals but are not necessarily hyperglycemic (28). Many normoglycemic individuals maintain normal blood glucose levels with a degree of muscle insulin resistance identical to those with type 2 diabetes (29).
Green tea contains the bioflavinoid epigallocatechin gallate (EGCG), which has been shown to be a safe and effective antioxidant. In a study in Japan, green tea was shown to reduce the risk for Type 2 Diabetes Mellitus onset. It has been shown to improve glucose tolerance in patients, and decrease blood sugar production and over-secretion in Type 2 Diabetes Mellitus patients. Green tea has also been shown to have an effective anti-angiogenesis factor, that is, it reduces problematic overgrowth of blood vessels, which may have a significant effect on preventing diabetic retinopathy. It has also been shown to promote fat oxidation and thermogenesis. Last, green tea can provide antioxidant protection for the pancreas and the fatty liver. A good dose is 200 to 400 mg a day. It’s also beneficial to drink organic green tea.
The theory of Five Phases, Wu Xing, is a means of classifying phenomena in terms of five basic processes represented by the elements wood, fire, earth, metal, and water. There exists a dynamic balance and relationship among the elements such that if the balance is interrupted or destroyed, pathological changes may occur. The clockwise movement of one element into the next (wood, fire, earth, and so forth) whereby one element generates, acts on, or promotes the following element, is referred to as the Sheng cycle. The Ke cycle represents an element acting on or controlling another element in a different order (Figure 2).3
In obese young people, decreased β-cell function has recently been shown to predict deterioration of glucose tolerance (4,78). Additionally, the rate of decline in glucose tolerance in first-degree relatives of type 2 diabetic individuals is strongly related to the loss of β-cell function, whereas insulin sensitivity changes little (79). This observation mirrors those in populations with a high incidence of type 2 diabetes in which transition from hyperinsulinemic normal glucose tolerance to overt diabetes involves a large, rapid rise in glucose levels as a result of a relatively small further loss of acute β-cell competence (3). The Whitehall II study showed in a large population followed prospectively that people with diabetes exhibit a sudden rise in fasting glucose as β-cell function deteriorates (Fig. 5) (80). Hence, the ability of the pancreas to mount a normal, brisk insulin response to an increasing plasma glucose level is lost in the 2 years before the detection of diabetes, although fasting plasma glucose levels may have been at the upper limit of normal for several years. This was very different from the widely assumed linear rise in fasting plasma glucose level and gradual β-cell decompensation but is consistent with the time course of markers of increased liver fat before the onset of type 2 diabetes observed in other studies (81). Data from the West of Scotland Coronary Prevention Study demonstrated that plasma triacylglycerol and ALT levels were modestly elevated 2 years before the diagnosis of type 2 diabetes and that there was a steady rise in the level of this liver enzyme in the run-up to the time of diagnosis (75).
Patients diagnosed with type 2 diabetes may discover that if they are overweight at diagnosis and then lose weight and begin regular physical activity, their blood glucose returns to normal. Does this mean diabetes has disappeared? No. The development of type 2 diabetes is a gradual process, too, in which the body becomes unable to produce enough insulin for its needs and/or the body's cells become resistant to insulin's effects. Gradually the patient goes from having "impaired glucose tolerance" — a decreased but still adequate ability to convert food into energy — to having "diabetes."
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.
