- BACKGROUND
Weight loss through low-calorie diets (LCDs) decreases visceral fat (VF). However, the effects on muscle mass, changes of dietary quality, and insulin sensitivity are unknown for Korean obese type 2 diabetic subjects. Therefore, this study examined such effects of LCDs. METHODS: A total of 30 obese type 2 diabetic subjects (body mass index, 27.0 +/- 2.2 kg/m2) were randomly assigned to an LCD or control group. Subjects on LCDs took 500~1,000 kcal fewer energy than their usual dietary intake (1,000~1,500 kcal/day) over the course of 12 weeks. The abdominal VF and femoral muscle mass were evaluated by computed tomography, and insulin sensitivity was assessed using an insulin tolerance test (Kitt; rate constant for plasma glucose disappearance, %/min). Dietary nutrient intake consumed by subjects was assessed by 3-day food records. RESULTS: The percent VF reduction was -23.4 +/- 17.2% in the LCD group and -9.8 +/- 11.8% in the control group after 12 weeks (P < 0.001, P = 0.002). However, significant decrease in femoral mass or proportional change of marcronutrient intake and mean adequacy ratio were not found in the LCD group, as compared to the control group. Insulin sensitivity improved in the LCD group, as compared to the control group (P = 0.040). CONCLUSION: LCD effectively improved insulin sensitivity and reduced abdominal VF without reduction of femoral muscle and dietary quality in obese type 2 diabetic subjects.

Abstract

- BACKGROUND
Combination fitness regimens (including aerobic and resistance exercises) are effective for improving cardio-respiratory fitness, reducing visceral fat and increasing insulin sensitivity in diabetic patients. The combination exercise intensity that a patient is capable of is limited by his or her aerobic capacity and one repetition maximum (1RM). We investigated the relationships between 1RM, aerobic exercise capacity and body mass index in patients with type 2 diabetes. METHODS: A total of 177 (men: 85, women: 92) diabetic subjects with HbA1c < or = 10% were enrolled. Muscle strength and 1RM were assessed bychest press (upper body) and leg press (lower body). We assessed aerobic capacity by VO2max and muscle mass by bioimpedance analysis. RESULTS: There was no correlation between 1RM and VO2max in type 2 diabetic patients (upper: P = 0.122, lower: P = 0.138 for men, and upper: P = 0.952, lower: P = 0.570 for women). However, 1RM was significantly correlated with muscle mass both in men and women (upper: r = 0.493, P < 0.001, r = 0.315, P = 0.002 lower: r = 0.437 P < 0.001, r = 0.307, P =0.003, respectively). There was also a significant correlation between 1RM and BMI. In obese male subjects with BMI > or = 25 kg/m2, we observed a significant correlation between muscle mass and BMI (r = 0.374, P = 0.032), but this correlation was not observed in women. CONCLUSION: Clinicians treating Korean type 2 diabetic subjects should recommend resistance exercise to their patients. In particular, obese women with diabetes may receive greater benefits by increasing muscle mass through resistance exercises.

Abstract

- BACKGROUND
It is difficult to improve muscle strength with only aerobic exercise training in type 2 diabetes patients. Resistance training is effective for improving muscle mass, muscle strength and insulin sensitivity. One repetition maxima (1RM), or the maximum amount of weight a subject can lift in a single repetition, may be a useful unit for evaluating the results of resistance training in type 2 diabetic patients. This study was aimed to assess baseline values for 1RM in a sample of Korean type 2 diabetes mellitus patients that are scaled for intensity and load of exercise, and to assess the relationship of 1RM to age. METHODS: A total of 266 (male: 95, female: 171) Korean patients with type 2 diabetes mellitus were included in the study sample. Maximal muscle strength was assessed by measuring 1RM for each subject (KEISER, Fresno, CA, USA). Two different exercises were used to measure 1RM: the chest press for the upper extremities, and the leg press for the lower extremities. RESULTS: Both upper and lower values of 1RM decreased with age in men and women; upper 1RM: r = -0.454, P<0.001 in men, r = -0.480, P< 0.001 in women, lower 1RM: r = -0.569, P<0.001 in men, and r = -0.452, P<0.001 in women. Values of 1RM significantly decreased in men only after the age of 70. In women, values of 1RM continuously decreased after the age of 60. CONCLUSION: The maximal muscle strength of individuals with type 2 diabetes decreases with age. We believe that resistance training is especially beneficial for type 2 diabetes mellitus patients after the sixth decade of life.

Abstract

- BACKGROUND
The results of previous studies suggest that portion size is a major factor dictating dietary energy intake. We investigated the relationship between frequencies of rice meals, bowl volumes, and dietary energy intake in a sample of patients with type 2 diabetes. METHODS: A total of 203 type 2 diabetes patients were enrolled in the study. A one-week food diary was collected from each patient and used to assess the types of meal consumed as well as the context of consumption. The volumes of the eating vessels (rice, soup and side dish bowls) used by each patient were obtained by comparisons to measuring cylinders, and dietary energy and macronutrient intake were estimated for each patient by consulting three-day dietary records. RESULTS: The mean age of the 203 subjects (male: 76, female: 127) was 53.9 +/- 9.1 years and the average body mass index (BMI) was 25.6 +/- 4.2 kg/m2. Among the subjects who ate three times per day, 96.4% consumed rice more than twice out of three meals. The median volume of rice bowls used by patients was 350 cc, of soup bowls was 530 cc and of side dish bowls was 260 cc. Portion size, as estimated by rice bowl volume, was not associated with BMI. Male subjects tended to eat out of larger rice and soup bowls (P < 0.001). Portion size was correlated with energy intake from rice (P = 0.021), but not with total energy intake (kcal/kg/day), especially in male subjects. CONCLUSION: Portion size of rice bowl was correlated with energy intake from rice, but not with total energy intake in male subjects with type 2 diabetes. To design effective meal planning methods for patients with type 2 diabetes, further prospective studies are warranted to investigate causative relationships between portion size andmetabolic conditions as well as variation by gender.

Abstract

- BACKGROUND
The food exchange-based meal plan is effective in controlling dietary energy intake with a macronutrient balance. However, it is difficult to practice for relatively low-literacy patients. As an alternative, we developed a system employing a standardized-sized bowl and investigated its effectiveness on achieving proper energy intake and macronutrient composition and patient compliance, compared to the conventional food exchange system in Korean type 2 diabetes patients. METHODS: Eighty subjects with type 2 diabetes were assigned to both the novel bowl-based meal plan group (BG) and the food exchange-based meal plan group (ExG). BG received limited simple instructions for the plan. Time spent for plan instruction was 10 min for BG and 40 min for ExG. Dietary energy and macronutrient intake were estimated with 3-day dietary records and patient comprehension of the plan was estimated with a 5-point Likert scale. RESULTS: After 12 weeks, dietary energy compliance showed no difference between the groups (BG: 103 +/- 10%, ExG: 101 +/- 17%). Both groups showed significant reduction in carbohydrate and protein intake and there was no difference in the proportion of carbohydrate, protein and fat in energy intake between the groups despite the shorter instruction time for BG. Following the instruction period, there was no difference in the understanding score between the groups. CONCLUSION: This bowl-based plan was equally effective as the food exchange-based plan in controlling dietary energy intake and macronutrient composition, as well as patient comprehension and compliance. Our novel plan may allow for more cost-effective methods in terms of time needed for plan instruction.
