The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.

The aim of the present study was to assess the effects of onion (Allium cepa) skin extract (OSE) on pancreatic lipase (PL), the key enzyme of the digestion and absorption of dietary fat in the small intestine, and to evaluate its potential for the inhibition of body-weight gain. OSE inhibited PL with an $IC_{50}$ of 53.70 mg/mL, which means as potent as 0.07635% of the activity of orlistat. At 3 and 4 hr after administration of OSE, the plasma triacylglycerol concentration was significantly lower in the OSE-treated rats than control. Body-weight gain and parametrial adipose tissue weights were significantly lower in mice fed the high-fat diet (fat comprises 31% of total calories) with 5%(w/w) OSE than in control. The results suggest that OSE may be an effective nutraceutical for the inhibition of body-weight gain.

This study was performed to investigate the effect of lysine-limited diets containing different levels of L-carnitine on body weight and lipid metabolism in obesity-induced adult rats. Eight-month-old male Sprague-Dawley rats (n = 90) were raised for one month with high fat diet (40% fat as calorie) to induce obesity. After induction of obesity, rats weighing 739.5 g were randomly blocked into three groups according to the body weight and raised for eight weeks with control diet (Co), 50% lysine-limited diet (-L), 50% lysine limitation with 0.3% pivalate diet (-L + P). Each of three groups was allotted to 0.0% L-carnitine (0.0% CT), 0.5% L-carnitine (0.5% CT) and 2.5% L-carnitine (2.5% CT) groups, respectively. The levels of AST, ALT, total protein and albumin in plasma were within the normal range. Daily food intake and calorie intake tended to be lower in 2.5% CT groups than those of other groups regardless lysine limitation or pivalate intake. And body weight gain and calorie efficiency ratio (weight gain (g) /calorie intake (100 kcal)) were significantly the lowest in 2.5% CT groups among all experimental groups regardless of lysine limitation or pivalate intake. The weights of perirenal, epididymal fat pads and brown adipose tissue in 2.5% CT groups were significantly lower than 0.0% CT groups. Plasma total lipid, triglyceride, total cholesterol concentrations in all groups were not significant by experimental compound. HDL-cholesterol concentrations in -L + P +2.5% CT group were highest in -L + P groups. Levels of hepatic total lipid, triglyceride and total cholesterol in 2.5% CT groups were tend to be lower those than in 0.0% CT groups regardless of dietary lysine limitation and pivalate intake. Fecal total lipid excretions of 2.5% CT groups were significantly lower than in 0.0% CT groups in all experimental groups. But fecal triglyceride excretions of 2.5% CT groups were significantly higher than 0.0% CT groups regardless of lysine limitation and pivalate. In conclusion, there was no difference on body weight and lipid metabolism by dietary lysine limitation and pivalate intake. And feeding of 2.5% L-carnitine was more effective than feeding of 0.5% L-carnitine and 0.0% L-carnitine in reduction of body weight, body fat and lipid metabolism.

The objective of this study was to investigate the effect of the fat reduction on the physicochemical and microbiological characteristics of fermented sausages during ripening and drying. Low fat fermented sausages were produced with different fat levels (30%, 20%, 10%, and 5%) under ripening conditions and fermented process. Samples from each treatment were taken for physicochemical and microbiological analyses on the 0, 1, 2, 3, 4, 5, 7, 10, 14, and 21st day of ripening. In proximate analysis, the fat reduction in sausages produced an increase in moisture, protein and ash contents during ripening and drying (p<0.05). The weight losses were significantly higher in high fat formulations during the first 4 days, whereas those were higher in low fat ones after 10 days of storage (p<0.05). Fat reduction was responsible for an increase in shear force values after 3 days of storage. The volatile basic nitrogen (VBN) value of the low fat samples was significantly higher (p<0.05). Low fat sausages reduced the extent of lipid oxidation. The lower fat level produced redder sausages. Total plate bacteria and Pseudomonas counts of sausages showed no significant differences. Production of low fat sausages resulted in the physicochemical and microbiological attributes equal to or better than the high fat sausages without negative effects, except only a higher VBN and weight loss.

Objective : Recently, obesity has increased at an alarming rate and is now a worldwide health problem. Natural dietary supplement, $CharmSlim^{(R)}$(C), is mixed pills, which consists of beans, black sesames, kelps, onions, adlay seeds, anchovies, pyogo mushrooms, green tea. Our study was performed to determine the weight-loss effects of natural dietary supplement, based on natural ingredients, in mice fed high-fat diet with an abundance of carbohydrates. Methods : Four groups of male ICR mice were fed different diets during 6 weeks: normal diet(NOR), high-fat (15%, w/w) diet(HF), high-fat supplemented with natural dietary supplement powdered 5%(C5) and 10%(C10) groups. We measured the changes of food intake, body weight and adipose tissues weights. Also we examined levels of lipid profiles in serum. Results : Body weight, liver weight and food efficiency ratio were significantly higher in the HF group than in NOR group. After 6 weeks of treatment, body weight, liver weight and adipose tissues weights (epididymal, perinephric, visceral and BAT) were significantly decreased in the C10 group when compared to the control HF group. The C10 group had markedly lower serum levels of total cholesterol and triglyceride when compared with HF group. Conclusion : These results demonstrate that this dietary supplement can suppress the increased lipid profiles, body weight and fat gains, thus could be considered as an effective adjunct in the treatment of obesity.

This experiment investigated whether yogurt containing fermented pepper juice (FPJY) affects cholesterol level in high fat and high cholesterol diet (HFCD) fed rat. Twenty five Sprague-Dawley male rats of 7 wk were divided into 5 groups, and fed following diets for 9 wk; CON (control diet), HFCD (HFCD), PY (HFCD supplemented with 2% of plain yogurt), LFY (HFCD supplemented with 2% of FPJY), and HFY (HFCD supplemented with 5% of FPJY). In the LFY group, hepatic total lipid level decreased significantly compared to the HFCD group (p<0.05). Serum HDL cholesterol level tended to increase and hepatic total cholesterol level decreased and were comparable to the CON group (p>0.05). In HFY group, body weight and hepatic total lipid level significantly decreased over the HFCD group (p<0.05). Serum and hepatic total cholesterol level, kidney, and body fat weights decreased, and were compared to the CON group (p>0.05). Liver weight decreased as FPJY content was increased. Results suggested FPJY would inhibit organ hypertrophy and accumulation of body fat, hepatic lipid, and cholesterol in HFCD fed rat.

The purpose of this paper it to investigate the differences in prevalence of obesity and body fat distribution on the variances of age. Height, weight, skinfold thickness and girth circumference on about 422 women residing in Cheju, Korea were surveyed. The results of analysis of the survey are as follows : 1) All the antropometric measurements except height were shown to increase with age. Weight is at its highest level between the age of 50-59. The measurement of skinfold thickness and girth circumference between the ages of 20-39 of the female subjects are significantly higher than the above 40's. However, there is no significant difference among the middle aged women. 2) Physical indices tend to increase according to age. Both BMI and RBW of women in their 50's are at their highest values, however, the index values of the women in their 60's decreased slightly (p<0.05). On the contrary, there is no significant difference in the percentage of body fat and total body fat content among the middle aged women surveyed. 3) According to this survey, 15.6% of the 422 subjects are assessed as being obese ; more specifically 4.4% of women in their 20's, 12.6% in 30's, 25.6% in 40's, 22.5% in 50's and 17.3% in 60's. 4) 39.4% among obese women proved to be upper body type women. Because the frequency of upper body type women became higher as the obese women aged, there is possibility that the pattern of fat distribution can change. 5) Weight is the most highly correlated with BMI(r=0.91), whereas weight as correlated with RBW, percentage of BF and WHR are 0.8, 0.66 and 0.44 respectfully. The conclusion of this survey is that it is better to estimate the value of total body fat and percentage of body fat than the value of BMI in the analysis of prevalence of obesity and its related factors of middle aged women.

Chitosan, hydroxycitrate and L-carnitine have been known to be antiobesity components. The purpose of this study was to evaluate the combined effects of chitosan, hydroxycitrate and L-carnitine mixture as a potential antiobesity supplement in overweight women. Pre-menopausal healthy females who were overweight (percent ideal body weight > 110) were included in this study. Forty-nine subjects randomly received a placebo (n = 25) or antiobesity-supplement (n = 24), which was a mixture of chitosan, hydroxycitrate, and L-carnitine. Before and after the eight-week experimental period, anthropometric parameters, blood components and computerized tomography were measured. At baseline, the two groups were well matched in terms of age, body mass index and lipid profile. After the eight weeks of potential antiobesity supplementation, the subjects' body fat percent had decreased significantly (p < 0.001) by 5.6% (39.1 $\pm$ 1 vs 36.9 $\pm$ 1%) while lean body mass increased (p < 0.01). Vsceral fat area at the L4 vertebra decreased significantly (p < 0.01) by 8.6% in the supplemented group and the total fat area at the L4 vertebra showed a tendency to decrease (p = 0.051) by 2.4%. Also, in the group given the antiobesity-supplement rather than the placebo, the fasting triglyceride level decreased significantly (p < 0.05) by 10.0%. In addition, serum total cholesterol levels in the antiobesity-supplement group showed a tendency to decrease (p=0.159) by 2.7% (194 $\pm$ 6 vs 189 $\pm$ 6 mg/dl). No side effects were found in either group during the intervention. In conclusion, the present study demonstrated that taking a mixture of chitosan, hydroxycitrate, and L-carnitine as a potential antiobesity supplement for eight weeks produced advantageous changes in the weight and visceral fat accumulation of overweight women without any side effects.

We investigated the effects of single and combined administrations of Lactobacillus species (L. plantarum, LP; L. gasseri, LG; L. casei, LC) on blood lipid metabolism and obesity in mice fed a high-fat diet (HFD). The mice were continuously supplemented with LP, LP/LG, or LP/LG/LC, along with HFD, for 12 weeks. The consumption of HFD led to significant increases in body weight, total cholesterol, and triglyceride levels compared to the normal control group. However, administration of LP, LP/LG, or LP/LG/LC to HFD-fed mice reduced body weight gain and showed a tendency to suppress the levels of total cholesterol, triglycerides, and LDL-cholesterol, while increasing HDL-cholesterol levels. The HFD group exhibited increased abdominal fat weight and larger adipocytes in the epididymal adipose tissue compared to the NC group. However, the administered probiotics led to a significant reduction in adipocyte size with decreasing tendency in abdominal fat weight compared with the HFD group. Additionally, the deposition of giant vesicular fat cells in the liver of the HFD group considerably decreased in the probiotic-administered group. Microbiome analysis revealed an imbalance in intestinal microbes in the HFD group, characterized by lower Bacteroidetes and higher Proteobacteria ratios. However, probiotic administration tended to restore the microbial distribution by controlling the abundance of Bacteroidetes and Proteobacteria, resulting in decreased Firmicutes/Bacteroidetes and Proteobacteria/Bacteroidetes ratios. These results suggest that single and combined administration of LP and other probiotics holds enormous potential in reducing obesity in HFD-fed mice as they regulate lipid metabolism, reduce adipocyte size, and restore the balance of intestinal microbes.

The aim of this study was to investigate the effects of herbal remedy using onion (HRO-1) supplementation on body weight change and cholesterol, triglyceride. free fatty acid, total lipid, phospholipid serum level in obesity mice. This study classified 32 of 4 weeks-old male C57BL/6 mice which have obesity caused by high fat fed into four groups of 8 mice and made the subjects medicated them HRO-1 for 6 weeks. Male C57BL/6 mice were divided into four groups; a normal group, a high-fat group, a high-fat group supplemented with HRO-1 (500 mg/kg), a high-fat group supplemented with HRO-1 (1000 mg/kg). In respect to the body weight change, there was statistically significant difference between the HRO-1 (1000 mg/kg) group compared to high-fat group (p<0.05). In the total cholesterol and LDL cholesterol level, there was statistically significant difference between the HRO-1 (1000 mg/kg) group compared to high-tat group (p<0.05). In the triglyceride and free fatty acid level, there was statistically significant difference between the normal group compared to high-fat group (p<0.05). In the total lipid and phospholipid level, there was statistically significant difference between the normal group compared to high-fat group (p<0.05). Also in the total lipid level, there was statistically significant difference between the HRO-1 group compared to high-fat group (p<0.05). The above results suggests that HRO-1 medicated is effective to prevention and treatment of obesity.
