Susan - 26 Jun 2006 01:32 GMT Nutr Metab (Lond). 2006 Jun 14;3(1):22 Low-carbohydrate diet in type 2 diabetes. Stable improvement of bodyweight and glycaemic control during 22 months follow-up. Nielsen JV, Joensson EA.
ABSTRACT: BACKGROUND: Low-carbohydrate diets in the management of obese patients with type 2 diabetes seem intuitively attractive due to their potent antihyperglycemic effect. We previously reported that a 20 % carbohydrate diet was significantly superior to a 55-60 % carbohydrate diet with regard to bodyweight and glycemic control in 2 non-randomised groups of obese diabetes patients observed closely over 6 months. The effect beyond 6 months of reduced carbohydrate has not been previously reported. The objective of the present study, therefore, was to determine to what degree the changes among the 16 patients in the low-carbohydrate diet group at 6-months were preserved or changed 22 months after start, even without close follow-up. In addition, we report that, after the 6 month observation period, two thirds of the patients in the high-carbohydrate changed their diet. This group also showed improvement in bodyweight and glycemic control. METHOD: Retrospective follow-up of previously studied subjects on a low carbohydrate diet. RESULTS: The mean bodyweight at the start of the initial study was 100.6+/-14.7 kg. At six months it was 89.2+/- 14.3 kg. From 6 to 22 months, mean bodyweight had increased by 2.7+/- 4.2 kg to an average of 92.0 ± 14.0 kg. Seven of the 16 patients (44%) retained the same bodyweight from 6 to 22 months or reduced it further; all but one had lower weight at 22 months than at the beginning. Initial mean HbA1c was 8.0 ± 1.5 %. After 6 and 12 months it was 6.6 ±1.0 % and 7.0 ±1.3 %, respectively. At 22 months, it was still 6.9 ± 1.1 % . CONCLUSION: Advice on a 20 % carbohydrate diet with some caloric restriction to obese patients with type 2 diabetes has lasting effect on bodyweight and glycemic control.

Nutr Metab (Lond). 2006 Jun 14;3(1):23 A low-carbohydrate diet may prevent end-stage renal failure in type 2 diabetes. A case report. Nielsen JV, Westerlund P, Bygren PG.
ABSTRACT: An obese patient with type 2 diabetes whose diet was changed from the recommended high-carbohydrate, low-fat type to a low-carbohydrate diet showed a significant reduction in bodyweight, improved glycemic control and a reversal of a six year long decline of renal function. The reversal of the renal function was likely caused by both improved glycemic control and elimination of the patients obesity. Insulin treatment in type 2 diabetes patients usually leads to weight increase which may cause further injury to the kidney. Although other unknown metabolic mechanisms cannot be excluded, it is likely that the obesity caused by the combination of high-carbohydrate diet and insulin in this case contributed to the patients deteriorating kidney function. In such patients, where control of bodyweight and hyperglycemia is vital, a trial with a low-carbohydrate diet may be appropriate to avoid the risk of adding obesity-associated renal failure to already failing kidneys.

Nutr Metab (Lond). 2006 Jun 21;3(1):24 Low carbohydrate diets improve atherogenic dyslipidemia even in the absence of weight loss. Feinman RD, Volek JS.
ABSTRACT: Because of its effect on insulin, carbohydrate restriction is one of the obvious dietary choices for weight reduction and diabetes. Such interventions generally lead to higher levels of dietary fat than official recommendations and have long been criticized because of potential effects on cardiovascular risk although many literature reports have shown that they are actually protective even in the absence of weight loss. A recent report of Krauss et al. (AJCN, 2006) separates the effects of weight loss and carbohydrate restriction. They clearly confirm that carbohydrate restriction leads to an improvement in atherogenic lipid states in the absence of weight loss or in the presence of higher saturated fat. In distinction, low fat diets seem to require weight loss for effective improvement in atherogenic dyslipidemia.

Far wiser would be variety with a balanced intake of the macronutrients (equal percentages of each) **and** much less intake (less than 32 ounces of food per day).

I don't know the history, but I assume the bad medical advice came first. Then the "sponsors" saw a good thing and jumped on board.

The diagnostic threshold was set deliberatly too high to diagnose most type 2s back in the 70s, I think it was, because there was no treatment or meters for home use and there was lots of employment and health insurance discrimination. Noble of them. Not so of those perpetuating those ranges, though, now that we know how much damage occurs with any fbg above 100 or post prandial above 140.
Unfortunately, this rationale has gotten lost in the years that gave us meters and more knowledge about prevention and the drug metformin, and lots of folks develop advanced diabetic complications while still running blood glucose in the "pre-diabetic" range. I'm talking peripheral neuropathies, nephropathy and retinopathies, along with autonomic neuropathies.
Those sponsors don't want us eating in a way that keeps us in normal healthy ranges of bg; it means doing without all or most of their products, except for generic metformin.

Sharon Hope - 27 Jun 2006 03:40 GMT Since you are on the topic of diabetes, did you happen to see the articles on the Beagle who won the lifesaving award? She actually dialed 911 (yes, on purpose) to save her master's life.

She is a specially trained diabetic service dog.
"Using their keen sense of smell, the animals can detect abnormalities in a person's blood-sugar levels. The dog periodically licks Weaver's nose to take her own reading of his blood-sugar level. If something seems off to her, she will paw and whine at him.
"Every time she paws at me like that I grab my meter and test myself," Weaver said. "She's never been wrong.""
Having known some child diabetics, I can't help but wonder why they don't all have dogs who lick their noses, which has to be far preferable to taking blood tests every day. Has to be much more fun, and lots of additional health benefits from having a best friend, vs a sharp tester.

Sharon, they don't need dogs to lick their noses to find they're running sugars that high, they need doctors and nutritionists to stop telling them to eat most of their calories from starches.

Another interesting turning point that happened in the 70s was Earl Butz's decision to encourage the growing of corn. Earl was the Sec. of agriculture . With all the resulting corn what to do with it became an issue. Answer whiskey and high fructose corn syrup. We are talking lots of carbs here. The latter is in just about everything. Perhaps the switch to ethanol will lower our carbohydrate consumption? However I hear it takes more energy to make it. If global warming is a reality carbon is still carbon. A rock and a hot place.
Gut feeling...blood sugar and heart issues will become more intertwined. Obesity, blood sugar and CAD require a new word. OBBSCAD?

They already are completely intertwined, which is why the drug pushers for both CVD and DM are doing everything they can to promote high carb, low fat diets.
If doctors and patients understood how rapidly and easily CVD and DM prevention and risk management were with low carb with or without exercise, their stock prices would plummet.
Syndrome X, metabolic syndrome, insulin resistance, hyperinsulinemia. Anyone curious enough to google up these terms with CVD, DM and even cancers (particularly pancreatic, prostate, breast and ovarian) will get the same shock of realization I once did.

I meant that stock prices for DM and lipid lowering and bp drug companies would plummet, along with the lipids, blood glucose and blood pressure of those who eat lower carb.
Low carbing drops bg and triglycerides like a rock, while typically raising HDL.

AHA and ADA Declare Truce in Metabolic Syndrome Squabble
By Peggy Peck, Managing Editor, MedPage Today Reviewed by Rubeen K. Israni, M.D., Fellow, Renal-Electrolyte and Hypertension Division, University of Pennsylvania School of Medicine June 26, 2006 Also covered by: Yahoo! News

€ Explain to patients who ask that the disputed metabolic syndrome is a compilation of a number of risk factors, including dyslipidemia, hypertension, obesity, and insulin resistance.
€ Be aware that both the AHA and ADA recommend using risk assessment algorithms. Review DALLAS, June 26 ‹ The American Diabetes Association (ADA) and the American Heart Association (AHA) have decided to paper over their public differences on the validity of the metabolic syndrome as a treatable diagnosis. To that end, both groups today issued a joint statement declaring that they remain "unified and committed to reducing the burden of diabetes and cardiovascular disease." The statement, which was being simultaneously published by Diabetes Care and Circulation, Journal of the American Heart Association, said the widespread publicity over the divergent views of the usefulness of metabolic syndrome as a diagnosis was becoming counterproductive to the overriding goals of both groups. "Unfortunately, some of the medical press have positioned the scientific issues related to the metabolic syndrome as a 'battle' between the American Diabetes Association and the American Heart Association, implicitly suggesting that cardiovascular disease risk factor identification and treatment is now questionable," they wrote. "We are concerned that the presumed dispute will lead to a reduction in the favorable trend of many aspects of cardiovascular disease risk factor reduction." The joint statement was co-authored by AHA president Robert Eckel, M.D., ADA president Robert A. Rizza, M.D., along with Rose Marie Robertson, M.D., and Richard Kahn, Ph.D., chief science officers of the AHA and the ADA, respectively. The joint statement emphasized agreement. It backed an emphasis on treating "a core set of risk factors (pre-diabetes, hypertension, dyslipidemia, and obesity)" as well as smoking. The statement sidestepped the genesis of the still-simmering disagreement‹a dispute that neither group tried to hide‹the definition of metabolic syndrome. Last year the ADA signed onto a European Association for the Study of Diabetes (EASD) statement published in the August issue of Diabetes Care. It said, "We found that the metabolic syndrome has been imprecisely defined, there is a lack of certainty regarding its pathogenesis, and there is considerable doubt regarding its value as a cardiovascular disease risk marker. Our analysis indicates that too much critically important information is missing to warrant its designation as a 'syndrome.' Until much needed research is completed, clinicians should evaluate and treat all cardiovascular disease risk factors without regard to whether a patient meets the criteria for diagnosis of the 'metabolic syndrome.'" A month later the AHA, along with the National Heart, Lung, and Blood Institute, issued an updated statement on metabolic syndrome, which it declared a real and growing health problem. The AHA/NHLBI statement included one major change-it identified fasting glucose as a key risk factor and dropped the threshold for elevated fasting glucose from 110 mg/dL to 100 mg/dL or higher, which matched the glucose threshold endorsed by the ADA. In a series of back and forth comments made at the European Society of Cardiology meeting and the EASD in last September, the two organizations traded soft jabs. Dr. Eckel, who is himself an endocrinologist at the University of Colorado, said the diabetologists raised some valid points about the metabolic syndrome definition. But he added there are "no doubts that the metabolic syndrome exists." At the same time Dr. Rizza of the Mayo Clinic in Rochester, Minn., said he was not at all disturbed by the difference of opinion. "The real issue is whether the concept of metabolic syndrome adds value to treatment of persons with diabetes." He suggested it did not. Dr. Kahn said from the ADA standpoint, "there doesn't appear to be any evidence that a metabolic syndrome diagnosis is helpful. To step back and say this (metabolic syndrome) doesn't exist is a train that is hard to stop and reverse, but more and more people are challenging the conceptŠI think the tide is actually turning on this concept." Now, however, the AHA and ADA say they are putting their disagreements aside in pursuit of the greater goal‹"a reduction in heart disease, stroke and new-onset diabetes." To that end they suggested that a useful tool for estimating risk of diabetes and cardiovascular disease is http://www.diabetes.org/diabetesphd/default.jsp, a free assessment tool that has been "extensively validated" in a number of studies yet is "rarely used in clinical practice." A low tech approach, which they say may also be an effective first step, is "simply ascertaining a person's blood glucose level, blood pressure, LDL cholesterol level, and tobacco use and noting the presence of obesity." In a vague reference to metabolic syndrome, the statement cautioned that even "borderline abnormalities, especially if they are multiple, may well presage future problems and should be addressed." The AHA/NHLBI defined metabolic syndrome as a group of metabolic risk factors in one person. Those risk factors include abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, insulin resistance, prothrombotic state and proinflammatory state.
Finally, the AHA/ADA statement concluded that despite "many unresolved scientific issues, a number of cardiometabolic risk factors have been clearly shown to be closely related to diabetes and cardiovascular disease: fasting/postprandial hyperglycemia, overweight/obesity, elevated systolic and diastolic blood pressure, and dyslipidemia. Although pharmacologic therapy is often indicated when overt disease is detected, in the early stages of these conditions, lifestyle modification with attention to weight loss and physical activity may well be sufficient."
