Unfortunately, too often physical activity is an underutilized therapy. Favorable changes in glucose tolerance and insulin sensitivity usually deteriorate within 72 h of the last exercise session; consequently, regular physical activity is imperative to sustain glucose-lowering effects and improved insulin sensitivity. Individuals with type 2 diabetes should strive to achieve a minimum cumulative total of 1000 kcal · wk-1 from physical activities. Those with type 2 diabetes generally have a lower level of fitness (VO(2max)) than nondiabetic individuals, and therefore exercise intensity should be at a comfortable level (RPE 10-12) in the initial periods of training and should progress cautiously as tolerance for activity improves. Resistance training has the potential to improve muscle strength and endurance, enhance flexibility and body composition, decrea...

Changes were made, as deemed necessary, on the basis of nutritional recommendations for persons with diabetes as understood in 1986. Major changes include rewriting the text to make it more useful in the education of persons with diabetes; changing the order of the exchange lists to emphasize a high-carbohydrate, high-fiber diet, as well as to better reflect the order of foods in menu planning; adding symbols to foods high in fiber and sodium; changing nutritive values for the starch/bread and fruit lists; adding lists of combination foods, free foods, and foods recommended only for occasional use; developing a data base; and initiating a plan for field testing and evaluation. The committee also developed a simplified meal planning tool, Healthy Food Choices, to be used for initial or "survival" level education. In poster f...

Goals for insulin-dependent and noninsulin-dependent diabetes mellitus (IDDM and NIDDM) differ due to the underlying pathophysiology of the conditions. This article discusses the nutrition management goals for IDDM and NIDDM and provides practical recommendations to achieve them. The authors supply a sample meal plan, a list of high-fiber and low-fat foods, a sample diet history, and a food record to facilitate assessment and patient behavior changes. NPs can use this information in practice when nutrition consultation is not available.

No evidence exists for the implementation of low-GI diets for a reduction in coronary heart disease (CHD) mortality, events, or morbidity. Observational studies report conflicting evidence on the role of low-GI diets in CHD and risk factors for CHD. Randomized clinical trials report a small reduction in total cholesterol (-6.6 mg/dL) from low-GI diets compared with high-GI diets, but no reduction in other risk factors, such as low-density lipoprotein or high-density lipoprotein cholesterol, triglycerides, fasting glucose, insulin, or body weight. Currently, the research suggests a minimal role for the implementation of low-GI diets in the prevention or treatment of CHD.

Interventions related to carbohydrate--amount and type--and alcohol are controversial. The role of the dietitian is to assist persons with the metabolic syndrome to make lifestyle changes that modify the factors that increase risk of diabetes and cardiovascular disease.

In type-1 diabetes, there are 4 studies (average duration approximately 4 weeks) comparing high versus low GI diets; none reported improvements in HbA1c, and although 2 reported improvements in fructosamine, 2 reported no differences. In type-2 diabetes, there are 12 studies (average duration approximately 5 weeks); 3 reported improvements in HbA1c and fructosamine, 5 reported no differences in HBA1c, and 3 reported no differences in fructosamine. In adults, there is limited evidence that a low GI diet is beneficial for weight loss or satiety. Three epidemiologic studies reported that a low GI/glycemic load (GL) is associated with a reduced risk of developing diabetes or prevalence of insulin resistance; however, 5 studies report no association between GI/GL and the risk of developing diabetes, fasting insulin or insulin resistance, or adiposity. In general, the total amount of carboh...

A systematic review of the weight loss literature found 17 articles in which women were the sole subjects and studies were a minimum of 1 year or longer in duration. Data were pooled and average weight loss and maintenance for women at 6 and 12 months was determined for each of the six interventions. Diet as the primary intervention resulted in a weight loss of approximately 7 kg at 6 months (approximately 13% of their initial weight), which was maintained to 12 months. When specific goals for physical activity or weight loss medications were combined with diet, better outcomes were experienced. Regardless of the intervention, at approximately 6 months a weight loss plateau occurred. All of the studies included at least monthly follow-up.

Breastfeeding is also recommended for infants of women with preexisting diabetes or gestational diabetes. Dietary Reference Intakes (DRIs) 2002 provides recommendations for energy and macronutrients for all ages and for pregnancy and lactation. During the first 6 months, infants receive an average of 500 kcal/d from human milk, and during the second 6 months 400 kcal/d. To cover this need for the first 6 months of lactation, women need an additional energy intake of 330 kcal/d plus the approximately 170 kcal/d that is supplied by the women's tissue stores, and for the second 6 months 400 kcal/d. The DRIs also set recommended levels for both the infant and mother for carbohydrate, protein, and fats. Women with type 1 diabetes may have problems initiating breastfeeding, and with hypo- and hyperglycemia during lactation. Breastfeeding may have long-term beneficial effects on glycemia in women with ges...

With protein intakes greater than 20% of energy intake there is an association between protein with increased albumin excretion rate. Once albuminuria is present, intervention studies suggest a beneficial effect on renal function with a reduction of protein to 0.8 to 1.0 g/kg/d with microalbuminuria and to 0.8 g/kg/d with macroalbuminuria. Restriction of sodium to 2400 mg/d or possibly for some to 2000 mg/d assists in the control of hypertension. In macroalbuminuria, there may be additional benefits in lowering phosphorus intake to 500 to 1000 mg/d. There is no strong evidence to suggest benefit from vegetable or plant proteins over animal protein, but there is evidence for benefit on renal function, glucose, lipids, and blood pressure from weight-maintaining diets meeting guidelines for a healthy diet.

To maintain body composition and nitrogen balance requires metabolic control and sufficient protein and energy intakes. However, because most adults eat at least 50% more protein than is required, people with diabetes appear to be protected from protein malnutrition when consuming a usual diet. Although nonessential amino acids undergo hepatic gluconeogenesis, peripheral glucose concentrations do not increase after protein ingestion. The fate of produced glucose is unknown. Protein does not contribute to sustained elevations of glucose levels, slow absorption of carbohydrate, or help in the treatment of hypoglycemia--advice often given to persons with diabetes. Protein is, however, just as potent a stimulant of insulin secretion as glucose. No long-term research is available to document that high-protein, low-carbohydrate diets are continued long-term or that weight lost initially is...
