title: [Comparison of a calorie-defined diet with the conventional exchange diet in Type 2 diabetes mellitus].
abstract: Meal planning using food exchange lists is problematic for many elderly type 2 diabetic subjects because the system is too complicated and too rigid regarding the daily meals. In addition, exchange lists are calorically imprecise. 12 non-insulin-dependent diabetic subjects agreed to participate in the present study (6 male, 6 female; age 40-82 years, weight 80 +/- 6 kg; HbA1c 7.3 +/- 0.3%); they received sequentially in randomized order either a diet using exchange lists, or a diet defined by total amount of allowed daily calories ("calorie diet"), both containing approx. 25 calories/kg ideal body weight/day, each for 8 weeks. The "exchange lists" mainly contained foods which were defined according to their content in carbohydrates (including bread exchanges, fruit exchanges, milk exchanges, vegetable exchanges). With the "calorie diet" the patients were relatively free during the day, the only rule being that they were allowed to consume a certain amount of calories per day, using a "calorie ruler". The results demonstrated that body weight decreased similarly during both diet periods (2.0 +/- 0.8 kg during the exchange list diet; 2.5 +/- 0.9 kg during the "calorie diet"). Fasting blood glucose concentration decreased during the "calorie diet" by 7% (p less than 0.05; fasting blood glucose at the end of the "calorie diet" was lower than after the exchange list diet (p less than 0.016). Serum lipoproteins were similar after both diet periods. 10/12 patients preferred the "calorie diet" because of its simplicity and flexibility. It allowed consumption of instant food which was calorically defined but difficult to convert into the exchange system.(ABSTRACT TRUNCATED AT 250 WORDS)
