Effects of Low Versus High Carbohydrate Diet During Rehabilitation on Cardiovascular Function and Metabolism in Type 2 Diabetes

2014-08-27 03:18:20 | BioPortfolio


Compared to the traditional low fat diet for overweight patients with type 2 diabetes, recent evidence shows that low carbohydrate/high protein diets lower triglycerides and postprandial glucose levels more effectively. However, it is not known, whether this diet can also improve the subclinically impaired myocardial function in type 2 diabetes. This prospective parallel group and cross over design study compares the effects of a low glycemic and insulinemic diet (LOGI®) with an isocaloric traditional low fat diet during a three weeks rehabilitation programme with aerobic exercise for overweight type 2 diabetes patients testing the hypothesis, that the low carbohydrate diet improves myocardial function and insulin resistance.


This is a single center, short term therapy controlled and prospective study with blinded analyses of the ultrasound data in 41 patients with type 2 diabetes either on dietary control or oral antidiabetic medication. After recruitment and informed consent, patients are randomized to two treatment arms matched for age and concomittant antidiabetic and cardiovascular medication In one treatment arm, the diet is based on the LOGI components: 25% low glycemic index carbohydrates, 30% protein, 45% fat, taken for 3 weeks combined with aerobic exercise, while in the other treatment arm, the isocaloric traditional low fat diet is based on 55% mixed glycemic index carbohydrates, 20 % protein and 25% fat taken for three weeks and combined with the same aerobic exercise protocoll but followed by a two weeks period with LOGI diet and maintained exercise. In both treatment arms, antidiabetic and antihypertensive medication are maintained and/or adapted as necessary and recorded.

All patients receive life style instructions and are updated in their skills of measuring quantity of foods and designing diet plans based on food groups. Laboratory, clinical and ultrasound investigations are performed before and at the end of the three weeks programme and, in the cross over group, also at the end of the subsequent diet programme.

Medical and Biotech [MESH] Definitions

A diet prescribed in the treatment of diabetes mellitus, usually limited in the amount of sugar or readily available carbohydrate. (Dorland, 27th ed)

A diet that contains limited amounts of CARBOHYDRATES. This is in distinction to a regular DIET.

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Regular course of eating and drinking adopted by a person or animal. This does not include DIET THERAPY, a specific diet prescribed in the treatment of a disease.

A diet that contains limited amounts of fat with less than 30% of calories from all fats and less than 10% from saturated fat. Such a diet is used in control of HYPERLIPIDEMIAS. (From Bondy et al, Metabolic Control and Disease, 8th ed, pp468-70; Dorland, 27th ed)
