Purpose : The purpose of this research is to examine the effects of circuit weight training and aerobic exercise on the bodily formation and abdominal fat area of obese female college students. Methods : The female college students whose BMI is over $25kg/m^2$ were divided into the circuit weight training group and the aerobic exercise group and circuit weight training and aerobic exercise were conducted on the respective group five times a week. Resultlts : 1. The tendency of statistically significant reduction in weight, body fat percentage, and BMI was shown in both the circuit weight training group and the aerobic exercise group but there were no significant differences between these groups. 2. The tendency of statistically significant reduction in total abdominal fat area, and subcutaneous fat area was shown in both the circuit weight training group and the aerobic exercise group but there were no significant differences between these groups. 3. Visceral fat area was reduced more in the aerobic exercise group than in the circuit weight training group Conclusion : It was confirmed that exercise alone in the state of no dietary treatment being given could cause obese people bodily formation.

The present study was designed to evaluate the usefulness of Sauropus. androgynus leaf (SAL) meal on reducing fat accumulation in broiler chickens. Eighty unsexed broiler chickens were allocated to four treatment groups with five replicates of four chickens each. SAL meal supplementation had no effect on body, leg, back, breast, wing, liver and heart weights, carcass protein, moisture and ash contents (p>0.05). Broilers fed diets supplemented with 30 g of SAL meal had lower feed intake with better feed conversion ratio (p<0.05) than did the control chickens. SAL supplementation at all levels significantly reduced fat accumulation in abdomen region, and liver (p<0.01), and in carcass (p<0.05). Higher SAL supplementation resulted in lower fat accumulation in the carcass ($r^{2}=0.94$; p<0.01), abdomen ($r^{2}=0.99$; p<0.01) and liver ($r^{2}=0.98$; p<0.01). The current study showed that a 30 g supplementation of SAL meal to the broiler diet was effective to improve feed conversion ratio without reducing body weight. SAL meal supplementation to the diet reduce fat accumulation in broiler chickens.

The present study was carried out to investigate the effect of pine oil on the body weight and lipid levels of serum in rats fed high cholesterol diet and high fat diet, Body weight, weight of various organs, and feeding efficiency ratio were measured to study the effect of pine oil on obesty at 4 weeks after an oral administration, Total cholesterol, triglyceride, total lipid, HDL-cholesterol and LDL-cholesterol were also analysed to identify the ameliorating effect of pine oil on lipid metabolism in serum of same rats, The results were summerized as follows; 1. The increase in body weight and feeding efficiency ratio induced by choleserol diet was less in pine oil treated rats, Furthermore, decrease in weight of liver, kidney, spleen, testis, and epididymis were observed in pine oil treated rats. 2, Associated with the decrease in body weight, there was a concomitant reduction in serum levels of total cholesterol, triglyceride, and total lipid in rats fed high cholesterol diet and high fat diet. respectively, after an oral administration of pine oil. 3. Serum levels of LDL-cholesterol was significantly decrease after an oral administration of pine oil in rats fed high fat diet. These results suggest that pine oil can ameliorate obesity and lipid metabolism in serum.

Various forms of fermented soybean products are well documented for their health benefits. The efficacy of anti-obesogenic effect of Doenjang, one of the most commonly used seasonings in Korean cuisine, has been reported only in animal models; thus, an evaluation of Doenjang needs to be conducted in human studies. We aimed to test the hypothesis that Doenjang supplementation reduces body weight and changes body composition in overweight adults. A total of 51 overweight adults participated in this study. A group of males with BMI ${\geq}23kg/m^2$ and waist to hip ratio (WHR) ${\geq}$ 0.90, and a group of females with BMI ${\geq}23kg/m^2$ and WHR ${\geq}$ 0.85 were randomly assigned to either a Doenjang supplement (9.9 g dry/day) group or a placebo group for a 12-week randomized, double-blind and placebo-controlled study. Anthropometric parameters, abdominal fat distribution by computerized tomography (CT) and blood components were measured before and after the intervention period. After the 12-week study, the Doenjang supplementation group had significant reductions in body weight (kg), body fat mass (kg) and body fat (%) compared to the placebo group, the supplementation of Doenjang resulted in a significant reduction in visceral fat ($cm^2$), although no changes were observed in total and subcutaneous fat are as ($cm^2$), serum lipid profiles and dietary intakes. The present study demonstrated that daily supplementation of 9.9 g dry/day of Doenjang for 12 weeks reduces body weight and visceral fat in overweight adults.

The milk product is one of the major foods which provide calcium for nutritional requirement. In addition to calcium, it supplies diverse nutrients including protein, potassium, vitamin A, vitamin $B_1$, and vitamin $B_2$. Adequate calcium intake throughout lifetime ensures optimum bone density and prevents osteoporosis in old age by reducing loss of bone mineral during growth and aging. The nutritional deficiency of calcium intake and spreading of osteoporosis in Korean population accentuated necessity of adequate calcium intake through milk consumption. Obstruction of milk consumption due to lactose intolerance should be overcome by educational programs for adequate milk consumption and low-lactose milk product developments. Consumption of milk products was reported to prevent high blood pressure in clinical studies and epidemiological investigations. As the feeding of milk increased, the body weight and fat of animal decreased in animal studies. The epidemiological investigations revealed that there was a negative correlation between the amount of milk consumption and the body fat. When calcium was provided as dietary supplement in the clinical trials, the body weight and body fat of subjects decreased. When calcium was particularly supplied as a part of milk, the body weight reduction rate was augmented. Calcium, vitamin D, and conjugated linoleic acid have been reported to exert a role in reducing cancer. The paramount importance of milk in nutrition as a source of calcium and other invaluable nutrients emphasizes consistent supply of milk products to adults as well as adolescents by dairy industry.

The effect of diet supplementation of Antheraea pernyi (A. pernyi) silk fibroin on the lipid metabolism and antioxidant defense status in high fat-fed mice was investigated. The animals were given normal control diet (NC group), high fat diet (HF group), or high fat diet supplemented with A. pernyi silk fibroin powder (HFS group) for 7 weeks. After the experimental period, the HF group showed significant increase in body weight, plasma and hepatic total cholesterol levels, and hepatic triglyceride concentration, and decreased activities of hepatic antioxidant enzymes relative to NC group. However, the HFS group exhibited marked reduction in body weight, plasma cholesterol and hepatic triglyceride levels, hepatic lipogenic enzyme activities, and lipid peroxidation rate, and higher high-density lipoprotein (HDL)-cholesterol level, fecal triglyceride content, and antioxidant enzymes activities compared with that of HF group. These findings demonstrate that dietary feeding of A. pernyi silk fibroin could improve the lipid metabolism and antioxidant defense system via regulation of hepatic antioxidant and lipogenic enzymes activities. Hence, this silk fibroin may be beneficial as a functional biomaterial for the development of therapeutic agent against high fat diet-induced hyperlipidemia and its related diseases.

Obesity is the most common nutritional disorder in the developed world and has become a global epidemic in recent years. In this study, Zanthoxylum planispinum extracts (ZPE) were evaluated on the effect on inhibition of pancreatic lipase and lipid metabolism by oral treatment for 2 months in high-fed diet obesity-induced Balb/c mice. The ZPE showed pancreatic lipase inhibitory activity with $IC_{50}$ of $0.3{\mu}g/ml$. No significant difference in feed intake was observed among the groups. The high-fat diet-treated Z. planispinum extracts groups (HFD+ZPE, 100mg/kg) significantly decreased body weight compared to the high-fat diet vehicle groups (HFD, p<0.05). The high-fat diet-treated Xenical$^{(R)}$ groups (HFD+Xenical, n=10, 30mg/kg) also showed a significant reduction of body weight compared to HFD (p<0.05). Biochemical parameters (triglyceride, total cholesterol, and high-density lipoprotein cholesterol) in HFD plus ZPE diet groups were significantly lower than those of the HFD groups (p<0.05). These results indicated that ZPE more effectively suppressed the effects of HFD on body fat gain with the inhibitory effect on pancreatic lipase.

This study was designed to evaluate the effects of high-carbohydrate (HC) or high-fat (HF) diet with hydroxycitric acid (HCA)-containing Garcinia cambogia in rats. Seventy male Sprague-Dawley rats were randomly divided into 7 groups and raised with experimental diets containing different HCA levels (0, 1.6, and 3.2%) and calorie sources (carbohydrate, fat) for 8 weeks. Energy intake was significantly reduced in rats fed a HC diet with HCA compared to the HC diet without HCA. Body weight gain was significantly reduced in HCA groups. In the diet groups, plasma total lipid and triglyceride (TG) levels of the HCA groups were significantly lower than those of the group without HCA. There were no significant differences in energy intake and plasma lipid profile in HF groups. These results suggest that HC diet with HCA was more effective in the reduction of energy intake, body weight gain, and plasma lipid contents than those of HF diet with HCA.

Obesity is a serious health concern, which has been linked to an increased risk for cardiovascular diseases and some cancers. The traditional obesity control program is expensive. Moreover, it is difficult to maintain a healthy body weight as well as reduce body fat. The long-term use of effective and tolerable medication is carefully recommended to control body weight. In addition to obesity control medications, health functional foods, related to body weight control, have become popular in the commercial market. Known mechanisms include lipolysis, appetite control, inflammation reduction, and lean body mass maintenance. Previous clinical trials have documented the efficacy of some health functional foods; however, there are limitations. Studies on the potential roles and efficacy of some health functional foods, including caffeine, green tea, protein supplement, probiotics, and arginine, were reviewed. More large-scale and randomized placebo-controlled trials should be conducted eventually.

This study examined the effects of com gluten (CG) and its hydrolysate consumptions on weight reduction in rats fed a high-fat diet. Eight-month-old male Sprague-Dawley rats (n=40) were fed a high-fat diet (40% calorie as fat) for 4 weeks. They were then randomly divided into four groups and fed the isocaloric diets with different protein sources for 8 weeks. The protein sources were casein (control group), intact CG (CG group), CG hydrolysate A (CGHA group, 30% of protein as peptides and 70% as free amino acids) and CG hydrolysate P (CGHP group, 93% of protein as peptides and 7% as free amino acids). Body weight gain, adipose tissue weights, nitrogen balance, absorptions of energy, protein and fat, lipid profiles in plasma, liver and feces and hepatic activities of camitine palmitoyl transferase (CPT), fatty acid synthase (FAS), malic enzyme (ME) and glucose-6-phosphate dehydrogenase (G6PDH) were assessed. The CGHA diet had the highest amount of BCAAs, especially leucine, and most of them existed as free amino acid forms. The CGHA group showed significant weight reduction and negative nitrogen balance. Protein absorption and apparent protein digestibility in the CGHA group were significantly lower than those in other groups. Adipose tissue weights were the lowest in the CGHA group. Activity of CPT tended to be higher in the CGHA group than in other groups and those of FAS, ME and G6PDH were significantly lower in the CGHA group than in other groups. In conclusion, the CGHA diet which had relatively high amounts of free amino acids and BCAAs, especially leucine, had a weight reduction effect by lowering adipose tissue weight and the activities of FAS, ME and G6PDH in experimental animals, but it seemed to be a negative result induced by lowering protein absorption, increasing urinary nitrogen excretion and protein catabolism.
