The study was designed to observe the effect of complete listing for 10 days on body fatness, serum leptin level and lipid profile in thirty women who were admitted to fasting Clinical Program in Kyung-Hee Oriental Medical Center. Most of the subjects had food habits of over-eating and preferred oily foods which was correlated to the increase of body weight and BMI during realimentation. Average loss of body weight was 7.98kg and waist-hip ratio was significantly decreased during fasting. Body weight showed significant positive correlation with body fat(r=0.8182), lean body mass(r=0.7797) and total body water(r=0.7563). Body fat was gradually reduced after 9 days fasting, but lean body mass was not diminished any more after 7 days luring. Serum leptin level was significantly decreased after luring and re-feeding. The leptin showed significant positive correlation with body weight(r=0.9324), body mass index(r=0.8279) and body fat(r=0.8376). The levels of serum total cholesterol and LDL-C were significantly increased but HDL-C level was significantly decreased after fasting which increased could be harmful for persons with hypercholesterolemia. VLDL-C and triglyceride levels were not significantly decreased after fasting. Serum total free fatty acid level was significantly increased after fasting. These data suggest that the best way of maintaining the reduced body weight was to carry out the modification of food habits and behavior in daily lift. It could not be recommended to repeat often complete luting for reduction of body weight. (Korean J Nutrition 33(1) : 42-48, 2000)

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.

The research was designed to study the effect of different fat sources and levels on Body lipid metabolizm and immune responses in Sprague-Dawely strain male rats. These effect of different fat sources compared with sesame Oil, Perilla oil and Beet tallow. Fat sources were divided into 3 groups respectively 7%, 15%, 30% fat level on diet weight basis. The experimental period was 54days. 1) The body weight gain was significantly low in NF group. In Sesame oil group and perilla oil group, low fat level groups were higher than medium, high fat level groups. But in Beef tallow group, high fat level groups were higher than low and Medium groups. 2) The weight of liver, kidney and epididymal fat ped tend to increse with increasing body weight. 3) The contents of triglyceride and total lipid in serum were significantly different with dietary fat sources and Perilla oil group was the lowest. 4) The contents of triglyceride and total lipid in liver were significantly different with dietary fat levels and high fat level group was higher than low fat level group. 5) Perilla oil group, compared with Beef tallow group, showed the higher excretion of cholesterol through feces and the higher deposit of cholesterol in liver. Therefore serum cholesterol level of Perilla oil group was lower than that of Beef tallow group. But eventhough Sesame oil is vegetable oil, Sesame oil did not showed an effect like Perllia oil on serum cholesterol level. 6) Weight of thymus decreased with fat levels particularly in vegetale oil. And it had on effect on mitogen response, mitogen response decreased with fat level in vegetable oil. But in Beef tallow, there was no difference in fat level.

The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), ％ body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and ％ body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; ％energy from snack decreased from 22％ to 14％, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3％ of the subjects continued to lose weight after completion of the program, while only 7.8％ gained weight. And 78.4％ of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.

The study was attempted to observe effects of voluntary exercise on energy expenditure and on storage of excessive energy into body fat in adult mice. Mice, body weight 25-30g, were divided into two groups, exercise and sedentary group. Voluntary exercize by running wheel was allowed for former group but not for the mice of the latter group which were restricted by limiting space allowance 13.5$\times$11.5$\times$15.0cm per mouse. During a period of 4 weeks of feeding trial, they were fed ad libitum starch-casein based diet added with $^3\textrm{H}$-glucose (D-[1-$^3\textrm{H}$(N)]-glucose) at a level of 20 nCi per g of diet. Measurements were made to study hematology, lipase activity in epididymal adipose tissue, total contents of body waste and fat, and radiactivity of $^3\textrm{H}$-glucose incoporated into body fat. Dietary intake, body weight gain and amount of voluntary physical activities were also measured. The results obtained ard summarized as follows; 1) Amount of metabolizable energy intake, body weight gain and body fat were not statistically different between the two group. However, mice of the exercise group tended to show lower body weight gain body fat contants, but higher energy expenditure than those of the sedentary group. 2) Radioactivity of $^3\textrm{H}$-glucose incoporated into body fat appeared lower for exercise group expressd on a whole body fat basis. The activity was, however, higher for exercise group when expressed based on per g of fat compared to that of sedentary group. 3) Exercise group showed also higher activity of lipase in epididymal adipose tissue than the other group. 4) Mice whose physical activities were restricted appeared to have lower levels of hemoglobin and hematocrit values than of the exercise group. These results seem to support the theory that turn-over rate of body fat is activated by exercise and to suggest that consumed energy is to be converted primarily into body fat before its use as energy source by oxidation even during a period of continuous energy expenditure by exercise.

This experimental study was designed to investigate the effects of Seunggijoui-tang on the weight of obese rats induced by high fat diet. A series of experiments have been conducted in order to measure the effects of above the body weight, serum and fat cell. The measurements have been performed on; (1) the increasing amount of body weight; (2) the quantity of total cholesterol, triglyceride, free fatty acid, total lipid, phospholipid, HDL-cholesterol and LDL-cholesterol in serum; (3) the size of the epididymal fat cell and the fat drops area in hepatic lobule. In the SG I (Group fed high fat diet and administered 42.5mg/100g extract of Seunggijoui-tang during 8 weeks), the weight decreased significantly throughout the whole research period. In the SG I & SG II (Group fed high fat diet and administered 85mg/100g extract of Seunggijoui-tang during 8 weeks), the serum total cholesterol, triglyceride, total lipid, phospholipid, LDL-cholesterol decreased significantly in comparison with control group. In the SG I, the serum free fatty acid decreased significantly in comparison with control group. In the SG I & SG II, the serum HDL-cholesterol decreased in comparison with control group, but this result showed no efficacy. In the SG I, the epididymal fat cell decreased significantly in comparison with control group. In the SG II, the fat drops area in hepatic lobule of rats decreased significantly in comparison with control group. Based on the above result, it is assumed that the clinical application of Seunggijoui-tang can help the treatment of obesity.

The purpose of this study was to determine changes in body composition and blood lipids and to analyze the effects of Danhak exercise for 3 months in older women. For this study, 35 female subjects 60 to 70 years of age were recruited and administered 90 min of Danhak exercise, five times per week for three months by a professional coach. The results of this study were as follows: At baseline, the mean BMI(body mass index) and body fat(%) were 23.9 kg/$(m)^2$ and 32.4$\pm$4.9(%), respectively. The mean WHR(waist-hip ratio) was 0.91$\pm$0.04 and all subjects were determined to be abdominally obese. A significantly lower body fat was observed after 3 months of Danhak exercise(p<0.05). However, there were no significant differences in BMI, WHR or body weight before and after exercise. Danhak exercise also resulted in a decrease in total cholesterol and an increase in HDL(high density lipoprotein, and these differences were significant. Taken together, the results of this study indicate that the effects of Danhak exercise were similar to those of aerobic exercise with respect to improve body fat(%) and blood lipid profiles, which suggests that Danhak is a profitable exercise for individuals aged 60 and over.

To investigate the effects of exercise-training on serum lipids, fat distribution and several parameters of body fatness(percent body fat, skinfolds thickness, body circumference) were assessed in 24 healthy male subjects submitted to an 8-wk high intensive exercise-training. Blood sample was taken twice, per and post exercise-training, Exercise-training took place 5 days a week and daily energy intake and expenditure were observed. The results obtained are summarized as follows: 1) Through exercise-training body weight (changes : 1.1$\pm$1.1kg ; p=0.000) and percent body fat (changes : 2.4$\pm$1.3% ; p=0.000) decreased significantly . 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$1.7mm and 0.2$\pm$1.9mm. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) Total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly changed by exercise-training while only triglyceride decreased (changes : 20.7$\pm$44.8mg/dl ; p<0.05). Changes in body weight were grately related to changes in total cholesterol. Changes in deep abdominal adipose tissue were related to changes in triglyceride.

Twenty eight non-lactating and non-pregnant adult Serra da Estrela ewes, ranging in body condition score (BCS) from 1 to 4 were used to study the relationships between BCS, live weight (LW), body composition and fat partition. Ewes were slaughtered and their kidney knob and channel fat (KKCF), sternal fat (STF) and omental plus mesenteric fat (OMF) were separated and weighed. Left sides of carcasses as well as the respective lumbar joints were then dissected into muscle, bone and subcutaneous (SCF) and intermuscular fat (IMF). The relationship between LW and BCS was studied using data from 1,396 observations on 63 ewes from the same flock and it was found to be linear. Regression analysis was also used to describe the relationships among BCS and/or LW and weights (kg) and percentages in empty body weight (EBW) of dissected tissues. The prediction of weights and percentages in EBW of total fat (TF) and of all fat depots afforded by BCS was better than that provided by LW. Only the weight of muscle and the percentage of bone in the EBW were more efficiently predicted by LW than by BCS. IMF represented the largest fat depot with a BCS of 1 and 2, whereas SCF was the most important site of fat deposition with a BCS of 3 and 4. Allometric coefficients for each fat depot in TF suggest that the fat deposition order in ewes from this breed is: IMF, OMF, SCF and KKCF. Results demonstrate that BCS is a better predictor than LW of body reserves in this breed and that LJ is a suitable anatomical region to evaluate BCS.
