The seven (7) housewives were used as subjects at three times per weeks for twelve (12) weeks in order to find out the effects of aerobic exercise and weight training on body composition and blood lipid. Each subject's weight, lean body mass, percent body fat, BMI and blood lipid were measured immediately after the training and the results compared with the same prior to exercises were obtained as follows ; 1. The weight and percent body fat of the subjects were slightly but not significantly decreased, however the lean body mass following training was significantly increased with 1.3 %. BMI S RBW were also not significantly decreased. 2. Calory intake was 1929.9 cal before the training and 1896.0 cal after the training, which doesn't shows much difference. 3. The blood lipid such as TC and LDL-C were a little increased after the training, but HDL-C shows significant increase of 22.7 %, and HDL-C/TC was significantly increased with 13.2 % (p<.05 ) as well. However, TG shows significant decrease (p<.05 ).

This studies were performed to functional food consisted of herb mixture having an effect on postpartum body weight control in 105 subjects(control group n=54, experimental group n=51). Mean age of control and experimental group were 29.3 and 29.1 Mean pregravida body mass index of control and experimental group were 22.8 and 21.5. Total weight gain during the period of pregnancy of control and experimental group were 19.1kg and 17.8kg. In this studies, changes in postpartum weight was measured until one year after parturition. Until 1 month after parturition, there almost had no changes in weight all of two groups. But after 2 month, change in weight loss between two groups was shown definitely. Mean weight loss of control group and experimental group were 2.3kg and 6.5kg after 2 month, 3.7kg and 9.8kg after 3 month, 5.0kg and 10.4kg after 1 year(p<0.01).

This study aimed to assess the prevalence of weight control behaviors and their association with food and nutrient intake among Korean adults. Study subjects were 7,340 Koreans aged 20 years and older in the 1998 Korean Health and Nutrient Survey. Cross-sectional data were collected on weight control behavior and diet using structured questionnaire by interview. Analysis of variance following after Duncan's multiple range test was used to test the differences in food and nutrient intake among three different weight control behavior groups(weight reducing attempt, weight gaining attempt, none). Current weight control behaviors were reported by 32% of the study subjects. There were significant differences in weight control behaviors between male and female subjects; weight reducing practices were 7 times greater than weight gaining practices among female subjects while it was only 1.5 times among male subjects. Weight control behaviors were not consistently associated with food and nutrient intake among male and female subjects. Moreover, greater food and nutrient intake were observed among those who trying to reducing weight than those who did not try. Therefore, it Is necessary to educate the Korean adults that balanced food and nutrient intake with sustaind weight control effort is the ideal way to achieve healthy weight.

This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

많은 연구자들에 의하면, 과체중인 사람이 체중을 감소시켰을 때 체내 대사 속도가 느려지고, 식욕 증가에 관여하는 호르몬의 변화가 일어난다고 한다. 그런데 사실 그들의 몸은 굶고 있다고 인식하여 괴식을 유도하므로 감소된 체중의 대부분이 원래 상태로 되돌아오게 된다. 하지만 연구자들은 체중 감량 후 과식하는 경향이 지속되는 것에 대해서는 간과해 왔다.

This study was attempted to evaluate the effectiveness of extract of fermented red pepper The extract of fermented red pepper was prepared from fermented red pepper puree and polydextrose. Sixteen female college students were participated in this 8 weeks weight control program. All subjects were randomly assigned to the Internet Diet (ID) group or Internet I, fermented red pepper (IR) group. Mean energy intake of ID group was 1,279.9$\pm$112.0 kcal (carbohydrate: 66.9%, protein: 17.4%, fat: 15.6%) and IR group consumed 1,223.8$\pm$57.1 kcal (carbohydrate: 66.3%, protein: 19.3%, fat: 14.4%) during program. The ID group lost 2.5$\pm$1.0 kg of body weight, 0,9$\pm$0,7 kg of fat mass and 1.6$\pm$0.7 kg of lean body mass, and the IR group lost 2.7$\pm$0.3 kg of body weight, 1.8$\pm$0.6 kg of fat mass and 0.9$\pm$0.7 kg of lean body mass. There was no significant differences in the loss of total body weight & lean body mass between two groups, however, the fat mass and the abdominal fat were significantly decreased in the IR group compared to the IC group (p<0.05) The ID group experienced a significantly reduced Resting Metabolic Rate (RMR), however, IC group slightly increased. The change of RMR between groups were significantly different (p<0.05) . There were no differences in the change of blood glucose, total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride between groups. Therefore, the intake of fermented red pepper doting the weight control program might decreased the body fat especially abdominal fat and prevent the decline of RMR during weight reduction period.

The objective of this study was to estimate the effects of change in body weight on racing time in Thoroughbred racehorses, using total 8,197 horses and 155,656 racing records collected from Korea Racing Association(KRA). The average body weight of the racehorses was 449kg, and the average body weights of stallion, gelding and mare were 460kg, 454kg and 441kg, respectively. Body weight of stallion was the greatest. The considerable loss of body weight was observed in March, April and May for mare, and in May, Jun and July for stallion and gelding. Overall, the body weight of the racehorses decreased in spring and summer, and increased in autumn and winter. The estimated heritability and repeatability for racing time were 0.237 and 0.525, respectively. The heritability for body weight estimated from total records was 0.612. The estimated heri- tabilities for body weight were 0.472, 0.578 and 0.555 for gelding, stallion and mare, respectively. As the change of body weight was greater than ±10kg, the racing time increased significantly. When the body weight changed more than ±20kg in comparison to the changes of body weight of ±5kg, the racing time increased by 0.3 second. When the change of body weight was ±0.5% of body weight, the racing time was the best(fastest). When the change of body weight was more than ±2.5%, racing performance decreased considerably.

We have studies in 38 subjects (19 control and 19 experiment) for development of functional food for postpartum body control. Mean age of control and experimental subjects were each other 30.4 and 29.0 years old, and mean body mass index were 20.2 and 21.4. Total weight gain during pregnancy of control and experimental subjects were 14.0kg and 19.8kg. We measured change of weight and liver activity after parturition for 3 months. It shows that weight not reduced until 30 days in postpartum but significantly decreased during 30 days to 90 days. The mean weight of control and experimental subjects were decreased 3.15kg and 6.46kg at 60 days(p<0.05), 4.47kg and 7.44kg at 90 days(p<0.05). In this study, hemoglobin, GOT and CPT level were not changes before and after of experiment, respectively.

The effects on deacidification of citrus fruits produced at early harvesting season for juice products were examined by heating treatment of raw fruits and electrodialysis of juice. Weight and total acidities were decreased by heating treatment for 40 hr at $25^{\circ}C,\;30^{\circ}C,\;35^{\circ}C\;and\;40^{\circ}C$, but $^{\circ}Brix$ and pH increased Sugar to acid ratio also increased. Total acidities were decreased from 1.25 (Oct30, 2004), 1.24 (Nov.5, 2004), 0.99 (Nov.13, 2004) and 0.98% (Nov.19, 2004) to 0.48 (Oct30, 2004), 0.51 (Nov.05, 2004), 0.37 (Nov.13, 2004) and 0.42% (Nov.19, 2004) by electrodialysis for 100 min respectively, and $^{\circ}Brix$ also slightly decreased, but solid to acid ratio was increased as a result. However pH and color remained almost unchanged by electodialysis. Also, free sugar contents of citrus juice little were changed, but organic acid content were decreased fairly. Narirutin and hesperidin content among flavonoids were slightly decreased by electrodialysis, but they were not significantly different. $K^+,\;PO_4^{2-},\;SO_4^{2-}\;and\;Cl^-$ content were decreased by electrodialysis, and $K^+$ contents decreased by more than 80% However, $Na^+$ consent was increased by about 2 times. Total polyphenol contents and electron donating abilities were decreased a little by electrodialysis but nitrite scavenging abilities were little changed. By acceptability test citrus juice prepared by electrodialysis for 100 min was superior to original citrus juice.

Effect of kochujang (Korean red pepper soybean paste) on the reduction of body weight and lipid levels of adipose tissues and serum were investigated in the rats fed a high-fat diet. Male Sprague-Dawley rats were fed for four weeks with diets containing either a normal diet (ND, based on the AIN-76TM diet), high fat diet (HFD, supplemented with 20% corn oil in ND), CK diet (10% commercial kochujang in HFD), TK I diet (10% 0 day (non-) fermented traditional kochujang in HFD), TKII diet (10% 6-month fermented traditional kochujang in HFD), or RPP diet (3% red pepper powder in HFD). CK, TK I and TKII in the diet significantly reduced the body weight gain compared to the control (HFD), whereas red pepper powder had no such effect. TKII supplementation in the high-fat diet reduced epididymal and perirenal fat pad weight significantly (p<0.05). Liver total lipid was lower in TKII diet group than other kochujang and RPP diet groups. TKII and CK decreased the content of triglyceride in epididymal and perirenal fat pad that increased by high-fat diet. The cholesterol content of the perirenal fat pad was the lowest in the TKII diet group. TKII was also effective in lowering serum cholesterol level. These results indicated that properly ripened (fermented for 6-month) traditional kochujang exhibited more suppressive effects on body fat gain and lipid levels of adipose tissue and serum than RPP, commercial kochujang and the kochujang without fermentation.
