Objectives : To provide an objective assessment of the effectiveness for weight loss of Mahuang. Methods : Effects were assessed by measuring changes in body weight, body mass index (BMI), body fat (kg, %),body muscle, and abdominal f3t ratio. The subjects of this study were healthy adults who agreed to participate in this study. Eligibility requirements include age between 20 and 50 and BMI more than 18.5 kg/m2. One hundred subjects were randomly assigned to two groups (control and Mahuang group) in a double-blind manner. Mahuang group subjects took 8g of Mahuang capsule/day for two weeks; control subjects took the same amount of indistinguishable placebo. We analyzed the body weight, body mass index, body fat, abdominal fat, body muscle and BMR (basal metabolic rate) before and after the study. Result After two weeks of clinical trial, body weight and BMI decreased in both groups, but the Mahuang group showed more significant decrease. On body fat, the Mahuang group showed significant decrease. while it increased in the placebo group. Although body muscle, body fat ratio and basic metabolic rate showed differences between the two groups, there was no statistical significance. Conclusion : It is suggested that intake of Mahuang may induce weight loss and body f3f decrease in healthy adults.

Distribution of wholesale carcass cuts and tissues was studied in Omani Dhofari bulls and steers raised under intensive management and slaughtered over a range of 110 to 210 kg body weight. The fore quarter of Dhofari cattle carcasses was heavier than the hind quarter with the chuck being the heaviest cut in the half carcass followed by the round whereas the flank was the lightest cut. Proportions of the fore quarter and its cuts increased whereas that of the hind quarter and its cuts decreased with increasing carcass weight. The fore quarter contained higher proportions of carcass tissues especially intermuscular fat than the hind quarter. The chuck and round contained the highest proportions of lean and bone and the flank the least. There was a general trend of increasing proportions of fat and decreasing proportions of lean and bone in carcass cuts and fore and hind quarters with increasing slaughter weight and age. As % total body fat (TBF), total carcass fat (TCF) increased whereas total non-carcass fat (TNCF) decreased. The largest proportion of TBF was deposited in the intermuscular site. Among the TNCF depots, the kidney and omental contributed the highest proportions whereas the pelvic and channel were the lowest. Proportions of M. rhomboideus and M. splenius increased in the half carcass whereas that of M. semitendinosus decreased as the cattle increased in size. The axial skeleton contributed 47.4-51.1, the fore limb 21.6-22.6 and the hind limb 23.9-26.2% of the total carcass bone. Proportions of axial skeleton increased whereas that of fore and hind limbs decreased with increasing slaughter weight and age. There were no major effects of castration on the distribution of weight of carcass cuts or carcass tissues. Steers had higher total body fat at 160 kg body weight and higher proportions of mesenteric, scrotal, pelvic, kidney and total non-carcass fat at 210 kg weight than bulls. As % of total body fat, steers fad significantly higher kidney and total non-carcass fat. There was little effects of castration on proportions of dimensions of individual muscles or bones.

This study was carried out with 505(243 boys and 262 girls in the Sungnam area) high school students to investigate the effects of eating behavior and anthropometric variables of weight and height on excercise performance. General characteristics about subjects and eating behavior were surveyed by questionnaire, anthropometric data were collected using two methods. The weight and height of subjects in 1996 were measured, but the same data in 1995 were collected from health records of each student. Body fat content of subjects was measured by BIA(Body Impedance Analysis). The grades of exercise performance, which were evaluated by physical education teachers were collected from records of a physical strength test score of each subject. From these, the following result were found. Groups with different eating behaviors such as skipping meals, overeating, food preference for a specific food(milk, carbonated drink etc.) were significantly different in their weight and height and body fat contents. The growth rate of height in first and second grade boys was significantly higher than that for grade boys. The amount of weight gain from second grade to third grade was significantly more than that of other grades both for boys and girls. The mean of BMI was $21.66\pm{2.95}$ in boy, $21.50\pm{2.62}$ in girls. The percentage of body fat was $24.91\pm{6.55%}$ in boy $34.73\pm{4.88%}$ in girls. Amounts of body fat were significantly increased in third grade. The group with higher fat content and the higher BMI group had lower values of physical strength. And the ability to exercises perform decreased significantly by promotion of grade. The other variables such as degree of concern about weight control and preference of exercise, and frequencies of exercise per week were significant factors in body fat content and physical strength. As a countermeasure for these problems, nutrition and health education must be developed for adolescents and a practical, proper physical activity guidance campaign for them is necessary.

This study examined the effectiveness of nutrition education and program using the diet rice bowl during a four-week diet program. Thirty-eight female college students were randomly assigned to a nutrition education (NE) group or a nutrition education and diet rice bowl (ND) group. The mean energy intake of the NE and ND group during the program was 1,130.8 kcal and 1,287.4 kcal, respectively. The total energy intake of both groups were significantly decreased during the program. In addition, the change of body weight and fat in both groups significantly decreased during the program. The NE group lost 2.8 kg of body weight and 1.4% of body fat, while the ND group lost 2.5 kg of body weight and 1.2% of body fat. The changes in total cholesterol and LDL-cholesterol in both groups also significantly decreased during the program. However, there were no significant differences in the changes of body weight, body fat mass, the total cholesterol and LDL-cholesterol between the two groups. This study could not identify a weight reduction effect of the diet rice bowl, however, this may be due to subjects' infrequent use of the diet rice bowl by their frequent meal skipping and eating-out in our study. Therefore, further studies regarding the compliance to the diet rice bowl should be conducted to examine its effectiveness on weight control.

This study was conducted to examine the effects of an 8-week weight loss program, on body composition, body shape satisfaction, body shape esteem in 15 obese children. This program included nutritional education and regular physical fitness. After completion of this program, height and body weight increased slightly but body compositions changed. BMI, degree of obesity, and body fat levels dropped slightly, however these differences were not significant. After the 8-week program body weight increased from $63.61{\pm}8.80\;kg$ to $64.07{\pm}9.11\;kg$, degree of obesity and BMI decreased from $151.73{\pm}13.62%$, and $29.08{\pm}2.35$ to $146.60{\pm}12.92%$, and $28.57{\pm}2.26$, respectively, and the percentage of body fat decreased slightly from $42.70{\pm}4.87%$ to $41.46{\pm}4.88%$. There were slight changes in weight of body muscle and lean body mass from $19.62{\pm}3.48\;kg$ and $36.17{\pm}5.78\;kg$ to $20.30{\pm}3.64\;kg$ and $37.16{\pm}6.18\;kg$, respectively. LBM and amount of muscle were higher after this weight loss program. The body shape esteem score increased from $7.60{\pm}4.01$ to $9.00{\pm}6.20$. There was no significant difference in body shape satisfaction before and after the program, and the participants also wanted to be leaner. Finally, body weight, BMI, and body fat showed negative correlations to body shape esteem.

Objectives: The purpose of this study was to investigate the ameliorative effects of the Epimedium koreanum Nakai (EK) on menopausal obesity in mice. Methods: To induce the menopausal obesity, female C57BL/6J mice were ovariectomized and fed with high fat diet for 12 weeks. 17β-estradiol was injected as a positive control and the extract of EK was orally administered 5 times per week for 6 weeks. Body weight, uterine weight and visceral fat weight were measured. The size of the adipocyte in visceral fat tissues was estimated by Hematoxylin and eosin staining. Fasting glucose level was estimated in serum. Results: Body weight and visceral fat weight were significantly decreased by EK treatment, while the uterine weight/body weight was increased in high fat diet-fed ovariectomized mice. The diameter of adipocyte in the visceral fat tissues was markedly reduced in EK-treated menopausal obese mice. In addition, the fasting blood glucose level was inhibited by oral EK administration. Conclusion: In conclusion, these results showed that EK has ameliorative effects on overweight after menopause. EK could be one of the alternative therapy for treating menopausal obesity.

This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.

Prevalence of an obese population has been increasing in Korea. Obesity is considered a major risk factor for chronic degenerative diseases. Specifically, prevalence of obesity is prominent for adult woman in Korea. In many weight control programs, weight change did not often show any beneficial effects for health. These facts discourage people in the program. Thus in this study, the anthropometry, blood pressure, serum biochemical indices and dietary habits were compared by percent body fat change for adult women to show the beneficial effects of the weight control program. Study subjects were 134. Measurements were done before and after the weight control program. Percent Body Fat (PBF) was measured by bioelectrical impedance analysis. Using PBF changes, subjects were grouped as I (more than 1% increase), M (${\pm}1%$ change), and D (more than 1% decrease). Data were analyzed using SPSS 12.0 program. Among the 134 participants, 13 increased their weight and 100 decreased. For PBF, 19 increased and 59 decreased. Statistical significant differences were shown for anthropometric assessments before and after for all weight, fat mass, percent body fat, waist-hip ratio and body mass index. I had increases, and D shows decreases. But the difference of D is large than M. Systolic and diastolic blood pressures decreased in all groups (p < 0.05). Fasting blood glucose decreased in all groups but were statistically significant only in D. Also triglyceride decreased in D (p < 0.05). Thus health conditions showed desirable changes in I < M < D in order. Dietary habit changes were desirable with only D. Weight, BMI and other indicators for obesity is not the real indicator for PBF. Recently it is easy to measure PBF. Thus, for weight control programs and to show benefits of the program, PBF is a good indicator for adult women in Korea.

Anti-obesity effect of a new dietary supplement (3D-relax) in high-fat fed rats. The aim of this study was to assess the effects of 3D-relax; a proprietary formulation containing hydroxycitrate (233 mg/g), carnitine (150 mg/g) and red pepper (150 mg/g); on body weight, body fat, and serum lipids levels in rats fed a high-fat diet. Male SD 7-wk-old rats (n=8) were fed a high fat diet [52% total dietary energy (E%) from fat, 15.4 E% protein, 32.6E% carbohydrate] with or without 3D-relax administration (1 g/kg body weight/day) for 3 weeks. Administration of 3D-relax significantly reduced the increase in body weight compared to the group fed high fat without 3D-relax. Food efficiency ratio (FER) tended to be decreased with administration of 3D-relax, but was not significant. The perirenal and epididymal fat pad weights of vats administered 3D-relax were significantly lower than those of the high fat group that did not ingest 3D-relax during the 3 weeks. The oral administration of 3D-relax significantly increased HDL-cholesterol level and lowered total cholesterol level compared to those of high fat alone group. These results suggest that 3D-relax reduced body weight and fat gains, and those effects are presumably linked to its inhibitory effects on lipogenesis.

This study was attempted to observe the possibility of body fat distribution and fasting serum insulin as potential predictive factors for obesity and energy intake. Subjects participated in this study were seventeen pairs of upper body type women and lower body type women whose age weight BMI daily energy expenditure per body weight were equally matched, Waist to hip girth ratio(WHR) was measured as a criteria of body fat distribution. Comparison of eating behavior between upper body type and lower body type women did not show any significant differences in meal size meal duration and energy intake per minute While serum free fatty acid level was lower in upper body type women percentage of body fat and fasting serum insulin triglycerde level of upper body type women were statistically higher than those of lower body type women(p<0.05) Our data may indicate the possibility that sympathetic nervous system activity was suppressed in upper body type women which needs ti be examined in future studies. In addition since the upper body type women were dieting over the period of survey with the intention of weigh loss we can conclude that upper body type women had larger variabilities than lower body type women in terms of daily energy intake level.
