The principal objective of this study was to assess the effects of low-calorie diets(LCD) for 8 weeks of medical nutrition therapy in individuals with BMI in excess of $23\;kg/m^2$. 41 over-weight or obese individuals (male=14, female=27, age $28.6{\pm}8.9\;yrs$), none of whom were diagnosed with a medical disease, were administered MNT 4 times over the study period. Approximately $1,100{\sim}1,300\;kcal/day$ were prescribed by a dietitian, via individualized counseling. Anthropometric parameters, daily nutrient intake, and blood levels of leptin, insulin, and lipid profiles were measured prior to and after the 8 weeks of the intervention period. We noted significant reductions in body weight, body mass index (BMI), fat mass (FM), visceral adipose tissue (VAT), abdominal skin-fold thickness, and waist circumference in both men and women. The mean body weight losses in men and women were $3.2{\pm}0.6\;kg$/8 weeks and $2.8{\pm}0.6\;kg$/8 weeks, respectively. However, the % of lean body mass (LBM) in men and women was shown to increase significantly (p<0.05). The daily intake of calorie, fat, protein, vitamin E, folate, and iron were significantly reduced during the LCD period. Blood levels of lipids and glucose were in normal range, and evidenced no changes after LCD. However, the serum levels of leptin in female subjects were significantly reduced (p<0.00l) from $8.9{\pm}4.8\;ng/mL$ to $6.9{\pm}4.8\;ng/mL$. In conclusion, 8 weeks of LCD with individualized counseling by a dietitian effectively reduced body fat and visceral fat in both men and women with BMI in excess of $23\;kg/m^2$.

The amount of ingested protein was 78.18 gr in 1974, 87.61 gr in 1975, 89,93 gr in 1976, and 81.65gr in 1977. The amount was higher than the R.D.A. (80gr) except 1974’s protein amount. 6. As for fat consumption, it was 27.18 gr in 1974, 40.96gr in 1975, 29.61gr in 1976, and 25.64gr in 1977. But these values were much lower than the R.D.A. (40gr) except for 1975’s. 7. In aspect of the minerals (Fe, Ca), intake of Ca was 462.34mg in 1974, 400.07 mg in 1975, 488.14 mg in 1976 and 440.95mg in 1977. The consumption of Ca was lower than the R.D.A. (600mg). Fe was 10.27mg in 1974, 8.54mg in 1975, 11.36mg in 1976 and 20.84mg in 1977. Most of them were higher than the R.D.A. (10mg) except 1975. 8. It was found that thiamine and riboflavin were ingested slightly higher than the R.D.A. (1.4mg, vit. $B_1$, 1.6mg, vit. $B_2$). The amount of niacin and ascorbic acid were also higher than the R.D.A. except 15.41mg of niacin in 1975.

The purpose of this work was to study the relationships between dietary intake and serum lipid profile in 293 adult subjects (mean age: $45.9{\pm}0.7$, men: 163, women: 130) who visited health promotion center. The anthropometric and biochemical blood indices were measured, and nutritional intakes were assessed using a food frequency questionnaire method. The subjects were divided by three groups in accordance with a standard for treating hyperlipidemia; those who had blood cholesterol levels above 240 mL/dL or triglyceride levels above 200 mL/dL were put into the risk group (Risk), while those with blood cholesterol levels below 200 mL/dL and triglyceride levels below 150 mL/dL were put into the control group (Control). Subjects who were between the two groups in terms of blood cholesterol and triglyceride levels were put into the borderline group (Borderline). Risk group showed significantly higher body mass index, body weight, waist circumference, and fat content compared to control group. The levels of calorie, carbohydrate, fat, and protein intake were significantly higher in the risk group than control group. There were significantly positive correlations between dietary calorie, carbohydrate, fat, and protein intake and blood triglyceride concentration. The blood HDL-cholesterol concentration had negative correlation with carbohydrate intake. These results suggested that overeating may be one of important factors affecting hyperlipidemia in Korean adults.

Objectives: With the increasing number of single households and so-called Honbab-jok, those who eat alone, people tend to enjoy convenient and simple meals, such as single dish meals. This study was performed to provide data on the energy and nutrient content, and nutritional adequacy of single-dish meal. Methods: From the literature reviews, 61 types of single-dish meals were selected, and divided into 4 groups (steamed rice, noodle, porridge, and sandwich burger), and a further 11 sub-groups (bibimbab, fried rice, topped rice, rolled rice/ warm noodle, cold noodle, seasoned noodle, dukgook/ porridge/, and sandwich, burger). In addition, 382 junior high school students from Gyeonggi, Sejong, Jeonbuk, and Chungnam areas were recruited for the survey. The survey questionnaires were composed of the characteristics, preference, and intake frequency of single-dish meals. The representative energy content (arithmetic mean) of single-dish meals were calculated, and compared with the energy contents of preference and intake frequency-weighted values adjusted. The representative nutrient contents, energy contribution ratio, and INQ (index of nutritional quality) of a single-dish meal were calculated for a nutritional adequacy evaluation. Results: The study subjects considered a single-dish meal as tasty, simple and fast to prepare, inexpensive, nutritious, and no low calorie food. The preference scores of all but 1 sub-group of singledish meals were ${\geq}5.00$ (5.00~5.97), and 1 sub-group (porridge) was 4.67 on a 7-point scale. The intake frequency of 11 sub-groups were 0.31~1.71/week, porridge was the lowest at 0.31 and warm noodles was the highest at 1.71. Fried rice, rolled rice, and warm noodle' intake frequency were ${\geq}1/week$. The representative energy of steamed rice, noodle, sandwich burger were 443, 429, and 428 kcal, respectively, and that of porridge was 264 kcal. Less than 5% differences in the representative energy of 4 groups were observed when adjusted for the preference or intake frequency-weighted values. The energy contribution ratio of macro-nutrients calculations showed that porridge was a high carbohydrate and low fat food, whereas sandwich burger were high fat and low carbohydrate foods. The INQ of calcium and vitamin C were less than 1.0 in all 4 food groups, but the INQ of protein and thiamin were > 1.0 in all 4 single-dish food groups. Conclusions: The representative energy in the 4 groups of single-dish meal was 264~450 kcal, which is a rather low calorie meal, and the energy contribution ratio of macro-nutrients were inadequate. The protein and thiamin levels were sufficient but the calcium and vitamin C levels were insufficient in all 4 groups of a single-dish meal judged by the INQ. The additional intake of fruits and milk dairy products between meals with a single-dish meal, supply of calcium and vitamin C may increase, which will result in an improved nutritional balance.

It is well known that malnutrition is a predictor of mortality in hemodialysis patients. The number of diabetic nephropathy patients is increasing rapidly. This study aimed to investigate nutritional status and nutrient intake according to the presence of diabetes among hemodialysis patients. The nutritional intake and general characteristics of outpatients at Ajou University Hospital (24 with diabetes and 30 without diabetes) were investigated between July and September 2015. Patients' general data were collected, and nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) was evaluated. Nutrient intakes were assessed according to 3-day food records. There was no significant difference regarding body weight between the two groups. However, the non-diabetic group showed a better nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) ($5.2{\pm}4.4$ vs. $8.0{\pm}4.3$ score, non-diabetics vs. diabetics, P<0.05). There was no difference in daily calorie intake ($1,473.9{\pm}370.5$ vs. $1,503.8{\pm}397.5kcal$) and protein intake ($60.3{\pm}19.7$ vs. $65.6{\pm}20.5g$) in those with diabetes. Intakes of vegetables protein, sodium, potassium, vitamin C, folic acid and fiber were significantly higher in the diabetic group compared to those of the non-diabetic group. There was no difference in daily nutrient intake between the hemodialysis weekday and weekend groups. The non-diabetic group had higher calorie and sodium intakes per meal in the hemodialysis weekday group, but the difference was not significant. Based on these results, intervention should be performed to improve nutritional status in consideration of diabetes and dietary patterns.

This study was conducted to investigate the effect of a 3 week low calorie diet (LCD) and a 9 week of behavior modification (BM) program on the weight loss, mineral and vitamin status in 22 obese women. The subject were healthy, obese (PIBW> $120\%$) women aged 20 - 50 Yr and not taking any medications known to influence body composition, mineral or vitamin metabolism During the LCD program, subjects were provided commercial liquid formulas with 125 kcal per pack and were instructed to have a formula for replacement of one meal and at least one regular meal per day within the range of daily 800 - 1200 kcal intake. During the BM program the subjects weekly attended the group nutrition counseling session to encourage themselves to modify their eating behavior and spontaneously restrict their energy intakes. The BM program focused on stimulus control, control of portion sizes and modification of binge eating and other adverse habits. The initial mean energy intake of subjects was 2016.9 $\pm$ 129.8 kcal ($100.8\%$ of RDA) and dropped to 1276.5 $\pm$ 435.7 kcal at the end of a 3 week of LCD program and elevated to 1762 $\pm$ 329.3 kcal at the end of a 9 week of BM program. Carbohydrate, protein and fat intakes were significantly decreased at the end of the LCD but carbohydrate was the only macro nutrient that showed significant decrease (p < 0.05) at the end of the BM program compared to baseline. Calcium and iron intakes decreased significantly (p < 0.01, respectively) with no significant changes in other micronutrients at the end of the LCD. The mean weight of the subjects decreased from 73.8 $\pm$ 8.0 kg to 69.2 $\pm$ 7.7 kg with LCD and ended up with 67.7 $\pm$ 7.1 kg after 9 weeks of BM. The 3 weeks of LCD reduced most of the anthropometric indices such as BMI, PIBW, fat weight, wast-to-hip ratio and subscapular and suprailiac skinfold thickness. The 9 weeks of behavior modification showed slight change or maintenance of each anthropometric measurements. Weight loss and decreased WHR with the diet program induced significantly decreased systolic blood pressure. SGOT, SGPT and serum insulin levels with improved serum lipid profiles. Biochemical parameters related to iron status such as hemoglobin, hematocrit were significantly decreased (p < 0.01) at the end of the LCD. But their mean values were within normal range. The mean serum 25 (OH) vitamin $D_3$ level significantly increased after whole diet program. Serum folate level significantly decreased after 12 weeks of diet program. In conclusion 3 weeks of LCD brought 4.6 kg reduction in body weight without risk of iron, zinc or vitamin D deficiency and 9 weeks of the BM was effective to maintain nutritional status with slightly more weight reduction (1.5 kg). However calcium intake and serum folate should be monitored during the LCD and BM because of increased risk of deficiencies.

The purpose of this study was to investigate the effect of medical nutrition therapy (MNT) on anthropometric measurements, quality of diets, and blood parameters through the weight loss program in over weight or obese women. The subjects (n=76, $age\;31.1{\pm}8.4y,\;weight\;70.3{\pm}7.9kg,\;BMI\;27.2{\pm}2.4kg/m^2$) without medical disease were treated with MNT 5 times for 12 weeks by dietitian. Anthropometric measurements included height, weight, fat mass, lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), and dietary pattern. The dietary pattern was assessed by daily energy intakes from breakfast, lunch, dinner, and snacks of calorie density, and numbers of eating. Blood levels of leptin, lipid profiles (total lipids, total cholesterol, LDL-cholesterol, HDL-cholesterol), and insulin were analyzed. Anthropometric measurements decreased significantly after MNT (p<0.001). Waist circumference was reduced most rapidly and tricep skin-fold thickness was reduced most effectively after 12 weeks of MNT. Daily energy intake, calorie density and numbers of eating incidence decreased significantly $0796.4{\pm}395.5\;vs\;1402.9{\pm}217.8\;kcal/day,\;162.3{\pm}56.5\;vs\;113.4{\pm}30.1,\;5.0{\pm}1.4\;vs\;3.8{\pm}0.4$, respectively, p<0.05). The daily energy intake from breakfast and snacks significantly decreased (p<0.001). Calories from snack, calorie density of snack and numbers of snacking also decreased (p<0.05). The mean scores of DQI significantly increased ($7.6{\pm}2.1\;vs\;6.5{\pm}1.6$, p<0.05). The plasma levels of total lipid, triglyceride (TG), total cholesterol, LDL-cholesterol and leptin decreased significantly after MNT ($489.8{\pm}100.4\;vs\;447.0{\pm}87.3mg/dL,\;187.7{\pm}34.0\;vs\;175.9{\pm}31.5mg/dL,\;115.2{\pm}29.2\;vs\;109.2{\pm}26.7mg/dL,\;15.7{\pm}7.6\;vs\;12.4{\pm}5.9ng/mL$, respectively, p<0.05). These results indicate that MNT efficiently reduced the body weight through the changes in dietary intake, dietary patterns and dietary quality. MNT also changed body composition and reduced the levels of plasma lipid, cholesterol and leptin.

The present study was conducted to evaluate the dietary fiber intake of 130 subjects, that included 49 subjects(29 form Wonju, 20 from Kangnung) with diabetes mellitus, 23 hyperlipidemia patients, and 58 normal subjects. After the type and amount of foods that a subject took for one day were investigated using the 24-h recall method, the intake of various nutrients and dietary fiber were calculated using a program that already contained the information on dietary fiber contents. The results showed that diabetics from Kangnung who did not undergo dietary therapy had more fat intake that those from Wonju, hyperlipidemia patients, and normal subjects thus, had more energy intake. Also, the crude fiber intake in male and female diabetics from Kangnung were 8.43${\pm}$3.47g and 3.35${\pm}$3.29g, respectively, showing significantly high amounts compared to those of male and female diabetics from Wonju, hyperlipidemia patients, and normal subjects; however, the intake of crude fiber per 1,000 kcal in males and females was not significantly different among the four groups. Also, the dietary fiber intake(14.8-19.8g/day) and the dietary fiber intake per energy unit(7.7-10.9g/1,000kcal) were not significantly different between the four groups. The dietary fiber intakes of diabetics and hyperlipidemia patients were not significantly different from those in normal subjects, and these amounts were significantly lower than recommended levels. Thus, the methods of increasing dietary fiber intake, such as developing low-calorie, high-dietary fiber foods or additives, needs to be researched.

Purpose: This study was conducted to investigate the level of nausea & vomiting, anorexia and food intake during the periods of chemotherapy and 14 days after discharge. Method: The subjects were 40 cancer patients(cervix cancer : 20 patients, stomach cancer: 20 patients) who had chemotherapy with Cisplatin & 5-Fu. Data were analyzed by mean & standard deviation, ANCOVA. Result: 1. The severity of nausea & vomiting with anorexia in cancer patients receiving chemotherapy was the highest at the 3rd day and then it gradually decreased. At the 14th day after discharge, nausea & vomiting with anorexia still remained with very low levels. 2. The amount of food intake was the lowest on the 3rd day and then gradually increased. However, it was 53.3-72.5% of the ordinary food intake on the 14th day after discharge. Calorie intake was 625.31 Kcal on the 3rd day and 1130.92 Kcal on the 7th day after discharge. 3. There were no significant differences in nausea & vomiting, anorexia, food intake, calory intake between those with cervix cancer and stomach cancer. Conclusion: In cancer patients nausea & vomiting and anorexia were severe and food intake was very poor during chemotherapy but afterwards they were gradually improved, but were not completely recovered on the 14th day after discharge. Therefore the nursing intervention regarding the increase of food intake was necessary during chemotherapy and after discharge.

The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age($\leq$49 yr group) and those in group II 50 years up($\geq$50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in $\leq$49 yr group and 519.50mg in $\geq$50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in $\geq$50 yr group were significantly higher than those of $\leq$49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.
