  • 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.

  • This study was carried out to investigate perceptions of body image, body satisfaction, and dietary habits of beauty art major and non-major college students in Gyeonggi province. A total of 312 self-administered questionnaires (beauty art majors=145; non-majors=167) were analyzed. The means for height, weight, and BMI were 161.7 cm, 51.4 kg and 19.7, respectively. There were more majors who were underweight according to BMI classification than non-majors. Sixty-six percent of the subjects had previous weight control experience, and there was no significant difference between the majors and non-majors. The mean score for current body image was 4.61 out of a possible 9 points in the majors, which was significantly lower than 4.95 in the non-majors, and their perception of an ideal body image was thinner than their current body image. Those with more weight control experience had currently heavier perceptions of their body. The mean score for body satisfaction was 2.60 out of a possible 5 points, which was lower than the mean score for their attitudes toward the importance of their bodies. The mean score for dietary habits was 2.80 out of a possible 5 points, and there was no significant difference with dietary habits according to weight control experience or BMI classification. In both the majors and non-majors, there was a significant positive correlation between BMI and perception of current body image (p<0.001, p<0.001), and a negative correlation between BMI and body satisfaction (p<0.01, p<0.001). In the major students, there were significant positive correlations between dietary habits and body satisfaction (p<0.01), and attitudes toward the body importance (p<0.05); therefore, the greater their body satisfaction and body importance, the higher their scores for dietary habits.

  • Objectives: This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both χ2 and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weight-control. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weight-control foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning 'slightly satisfied' and 'slightly dissatisfied', respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.

  • Objectives The purpose of this study is to find out the effect of KyungOcGogamibang(KOGE) on the growth of rats. Methods First of all, we divided male Sprague-Dawley rats into 4 groups(KOGE1, KOGE2, KOGE3 and control group). Then KOGE1, KOGE2 and KOGE3 groups were administered with KOGE water extracts once a day at a dosage of 250, 500, 1,000mg/kg respectively for 3 weeks. The control group was administered with normal saline in the same manner. We measured the rat's body weight, amount of body weight increased, length of femur, serum GH, serum IGF-Ⅰ, serum TSH and serum testosterone after each week of administration. Results 1. There were significant changes of the rat's body weight, the length of the femur, the level of GH, IGF-Ⅰand TSH in KOGE1 groups. 2. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE2 groups. 3. There were significant changes of the rat's body weight, the length of the femur, the level of IGF-Ⅰand TSH in KOGE3 groups. Conclusions According to the results above, rat in KOGE group have been increased their body weight, length of femur, serum GH, serum IGF-1 compared to the control group. This study shows that groups of KOGE have an effect on promoting the growth, thus it is expected to treat growth problems for children.

  • Purpose: Ketogenic diets (KDs) have anti-obesity effects that may be related to glucose control and the gut microbiota. This paper hypothesizes that KD reduces body weight and changes the insulin sensitivity and gut microbiota composition in a mouse model of diet-induced obesity. Methods: In this study, C57BL/6 male mice were assigned randomly to 3 groups. The assigned diets were provided to the control and high-fat (HF) diet groups for 14 weeks. The KD group was given a HF diet for 8 weeks to induce obesity, followed by feeding the KD for the next 6 weeks. Results: After the treatment period, the KD group exhibited a 35.82% decrease in body weight gain compared to the HF group. In addition, the KD group demonstrated enhanced glucose control, as shown by the lower levels of serum fasting glucose, serum fasting insulin, and the homeostatic model assessment of insulin resistance, compared to the HF group. An analysis of the gut microbiota using 16S ribosomal RNA sequencing revealed a significant decrease in the proportion of Firmicutes when the KD was administered. In addition, feeding the KD reduced the overall alpha-diversity measures and caused a notable separation of microbial composition compared to the HF diet group. The KD also led to a decrease in the relative abundance of specific species, such as Acetatifactor_muris, Ligilactobacillus_apodemi, and Muribaculum_intestinale, compared with the HF group. These species were positively correlated with the body weight, whereas the abundant species in the KD group (Kineothrix_alysoides and Saccharofermentans_acetigenes) showed a negative correlation with body weight. Conclusion: The current study presents supporting evidence that KD reduced the body weight and altered the insulin sensitivity and gut microbiota composition in a mouse model of diet-induced obesity.

  • The purpose of this study was to investigate the effects of wax gourd on body weight, body fat, triglyceride, leptin and fat cell size in rats fed medium fat Male Sprague Dawley rats were fed with experimental diet containing total dietary fat at 20% of calorie with wax gourd (WG) for 4 weeks. Forty rats were divided into 4 groups including control, 5, 10, and 15% (w/w) WG supplement The results showed that weight gain was significantly higher in 5% WG than that in control (p<0.05), but was not different among the WG supplement groups. Total fat weight was significantly decreased in both 10 and 15% WG supplement groups than that of control. The levels of triglycerides and free fatty acids in the plasma were significantly decreased, particularly in 15% WG supplement group (p<0.05). The levels of leptin was not significantly different among the experimental groups. Fat cell size was significantly decreased in WG supplement groups compared to that of control group (p<0.05). Correlation among the parameters demonstrated that weight gain correlated positively with total fat weight, the levels of leptin and triglycerides. Taken these results together, 15% WG supplement diet substantially reduces total fat weight, triglycerides and free fatty acids levels and fat cell size in the rat fed midium fat.

  • In middle-aged men, abdominal obesity has been an important risk factor of coronary artery disease (CAD) as well as a predictor of hypertension, dyslipidemia, insulin resistance and glucose intolerance. Particularly, risks from abdominal obesity increase when adipose tissue accumulates in visceral compartment. Many studies showed that weight reduction by caloric restriction improves abdominal obesity and reduces lots of cardiovascular risk factors. Testosterone treatment also results in a significant decrease in visceral fat area and normalizes endocrine metabolism. However there is no study that compare the effect of caloric restriction with that of testosterone treatment. The purpose of this study is to investigate the effect of caloric restriction and that of testosterone treatment on body fat distribution, serum lipids and glucose metabolism in male patients with CAD. Forty five middle-aged overweight-obese men with CAD participated in 12 weeks' program. They were matched with age, body weight, body mass index (BMI) and divided into three groups : control group (n = 15) , caloric restriction group (-300 kcal/day, n = 15) and testosterone treatment group (testosterone undecanoate tablets, n = 15) . After 12 weeks, control group did not have any changes in anthropometries, lipid profile, body fat distribution, glucose metabolism and hormonal status. Expectedly, caloric restriction group showed decreases in body weight, BMI, waist to hip ratio, % body fat. Ten percentage of total cholesterol and 23% of triglyceride in serum were also decreased. In body fat distribution, total fat areas at both L1 and L4 levels were significantly reduced in this group without reduction in muscle of thigh and calf. However, testosterone treatment group did not have any significant changes in body weight, % body fat, serum lipid profile and abdominal fat distribution. In conclusion, weight reduction by caloric restriction is more beneficial in body fat distribution and serum lipid level than testosterone treatment in overweight male patients with CAD. This result suggests that modest weight reduction is possible to help decrease risk factors of CAD.

  • Obesity rates are increasing worldwide, associated with excess acute and chronic disease risk. In most countries, obesity rates among women exceed rates in men, particularly during the post menopausal years. Many factors affect body weight and appetite, including age, metabolic rate, physical activity level, stress, cultural factors, socioeconomic status, health status and health literacy, diet composition, attitudes, and beliefs. Gender affects appetite and body weight indirectly by altering factors contributing to food choice. However, there is emerging evidence that gender affects appetite and body weight directly, altering the physiological control systems regulating appetite. The follicular menstrual cycle phase (estrogen-rich) is associated with relative suppression of appetite. Lower estrogen levels are associated with increased food intake, body weight gain, and altered body fat distribution in humans and animals. This paper reviews the linkages between estrogen and appetite regulation. While relationships among appetite, body weight, and gender-linked hormones are complex, research elucidating these interrelationships could lead to development of gender-specific treatment approaches for obesity and appetite dysregulation.

  • Objectives: This study was conducted to investigate the experience and perception among adult women regarding weight control and the consumption of weight-control foods or health functional foods based on their body mass index (BMI). Methods: The subjects were 634 adult women from the Chungcheong province, Korea, and data were collected through a self-administered questionnaire from July 2021 through September 2021. The subjects were divided into four groups based on their BMI status: underweight (< 18.5 kg/m2, 7.6%), normal weight (18.5 ~ 22.9 kg/m2, 53.3%), overweight (23 ~ 24.9 kg/m2, 19.7%), and obese (≥ 25 kg/m2, 19.4%). Results: Over the past 3 years, almost two-thirds (68.6%) of the adult women had tried weight control measures, despite the fact that a significant proportion of them were normal or underweight. More importantly, 57.6% of subjects reported the consumption of weight-control foods, with a lower proportion in the underweight (35.4%) group compared to the normal (56.2%), overweight (62.4%), and obese (65.0%) groups. The food items used for weight control were mostly salads, chicken breasts, low fat (soy) milk, slimming tea, protein shakes, low-calorie cereals, and energy/protein bars among others. In addition, one-third (31.1%) of the subjects reported the use of health functional foods containing ingredients for fat reduction. A significantly higher proportion of these was from the overweight (36.0%) and obese (38.2%) groups compared to the underweight (20.8%) and normal weight (28.1%) groups. Products containing Garcinia cambogia extract, green tea, or Cissus extract, were popular among users. Subjects who were obese had a poorer perception of their health and body. Most subjects felt the need for correct information regarding weight control, but this number was significantly more in the higher BMI groups. Conclusions: Our results suggest that the use of weight-control foods or health functional foods is popular among adult women, especially those who are obese. Thus, nutrition education courses covering facts about weight control and practice need to be developed and provided based on the BMI status of subjects.
