Objective: To investigate the relationship between obesity/overweight and binge eating episodes (BEEs) in a large nonclinical population. Research Methods and Procedures: Consumers at shopping centers in five Brazilian cities (N = 2858) who participated in an overweight prevention program were interviewed and had weight and height measured to calculate BMI. Results: Prevalence of overweight (BMI = 25 to 29.9 kg/m2) was 46.6% for men and 36.6% for women. Obesity (BMI ≥ 30 kg/m2) was about two‐thirds of the prevalence of overweight. BEEs (subjects who binged one or more times per week over the last 3 months) in normal‐weight individuals was 1.4% for men and 3.9% for women, whereas in overweight/obese, these prevalences were 6.5% and 5.5%, respectively (p < 0.01). After adjustment for age, socioeconomic variables, and childhood obesity, those who reported BEEs had an odds ratio of being overweight/obese of 3.31 (95% confidence interval: 1.11 to 9.85) for men and 1.73 (95% confidence interval: 1.05 to 2.84) for women. Discussion: These findings indicate a strong association between episodes of binge eating and overweight/obesity, mainly among men. 相似文献

Objective: The objective was to test the hypothesis that, in women, the association between obesity and impairment in psychosocial functioning is mediated by levels of weight and shape concerns and/or binge‐eating frequency. Research Methods and Procedures: Self‐report measures of eating disorder psychopathology, mental health functioning, subjective quality of life in the psychological and social domains, and days “out‐of‐role” associated with any (physical or mental) health problem, were completed by a community sample of women classified as obese (BMI ≥30 kg/m2, n = 639) or non‐obese (BMI <30 kg/m2, n = 4253). For each of the dependent measures, regression models were used to test the hypothesis of mediation by comparing the strength of the relationship between independent and dependent variables with and without inclusion of the putative mediator in the regression model. Results: On each measure, the conditions for perfect mediation were satisfied when weight or shape concerns acted as the putative mediator, indicating that there was no association between obesity and functional impairment after controlling for weight or shape concerns. In contrast, associations between obesity and impairment in psychosocial functioning remained highly significant when binge‐eating frequency was the putative mediator. Discussion: The findings suggest that in women, weight and shape concerns are an important mediator of the relationship between obesity and impairment in psychosocial functioning, whereas binge eating may not be of primary importance. A greater focus on body acceptance in obesity treatment may be indicated. 相似文献

Objective: To assess whether parental overweight status and disinhibited overeating are predictive of daughters’ accelerated weight gain and disinhibited overeating. Research Methods and Procedures: Participants were part of a longitudinal study of girls (N = 197) and their parents. Measured height and weight were used to calculate BMI [weight (kilograms)/height (meters)2]. Parents’ disinhibited eating behavior was assessed using the Eating Inventory. Girls’ disinhibited eating was assessed using a behavioral protocol to measure eating in the absence of hunger. Girls were classified based on parental overweight at study entry into four groups: neither, mother only, father only, or both parents overweight. Results: Girls with both parents overweight had the most rapid increases in BMI from 5 to 13 years of age; BMI increased most slowly among the neither parent overweight group, with intermediate increases in BMI among mother only and father only overweight groups. Daughters with both parents overweight at study entry were eight times more likely to be overweight at age 13, controlling for daughters’ weight at age 5. Girls with both parents overweight had higher levels of disinhibited eating across all ages than all other groups. Although girls in all parental weight status groups showed increases in disinhibited eating over time, girls with both parents overweight had larger increases in disinhibited eating over time compared with all other groups. Discussion: Girls growing up in families differing in parental overweight had divergent developmental trajectories for BMI and disinhibited overeating. Findings reveal the need to focus prevention efforts on overweight parents of young children. 相似文献

Objective: The aim was to investigate the association between breakfast consumption and long‐term weight gain in an adult male population. Research Methods and Procedures: We evaluated prospective data on 20,064 U.S men, 46 to 81 years of age, who participated in the Health Professionals Follow‐up Study. Data on body weight, dietary factors, and lifestyle variables were obtained by validated questionnaires. We examined weight gain during 10 years of follow‐up. Results: Overall, 5857 men had a weight gain of 5 kg or greater during 10 years of follow‐up. Breakfast consumption was inversely associated with the risk of 5‐kg weight gain after adjustment for age [hazard ratio (HR) = 0.77 (95% confidence interval [CI], 0.72 to 0.82)], and this association was independent of lifestyle and BMI at baseline [HR = 0.87 (95% CI, 0.82 to 0.93)]. Fiber and nutrient intakes partially explained the association between breakfast consumption and weight gain. The inverse association between breakfast consumption and weight gain was more pronounced in men with a baseline BMI of 25 kg/m2 or lower [multivariate HR = 0.78 (95% CI, 0.70 to 0.87)] than in men who were overweight at baseline [HR = 0.92 (95% CI, 0.85 to 1.00)]. Furthermore, we observed that an increasing number of eating occasions in addition to three standard meals was associated with a higher risk of 5‐kg weight gain [HR = 1.15 (95% CI, 1.06 to 1.25, for ≥2 vs. 0 additional eating occasions)]. Discussion: These findings suggest that the consumption of breakfast may modestly contribute to the prevention of weight gain as compared with skipping breakfast in middle‐aged and older men. 相似文献

Objective: To examine the relationship among attempts to lose weight, restraint, and eating behavior in outpatients with binge eating disorder (BED). Research Methods and Procedures: Participants were 93 consecutive outpatients evaluated for a clinical trial who met Diagnostic and Statistical Manual, Fourth edition criteria for BED. The Eating Disorder Examination Interview was administered to assess attempts at weight loss, restraint, different forms of overeating, and the attitudinal psychopathology of eating disorders (i.e., concerns regarding eating, shape, and weight). In addition, the Three‐Factor Eating Questionnaire was used to assess cognitive restraint, hunger, and disinhibition. Psychometrically established measures were given to assess body dissatisfaction, depression, and self‐esteem. Results: The majority of participants (75.3%; N = 70) reported attempting to lose weight, but only 37.6% (N = 35) reported dietary restraint on at least half the days of the month. Dietary restraint and cognitive restraint were not associated with any form of binge eating or overeating. Dietary restraint and cognitive restraint were positively correlated with weight concern, shape concern, and body dissatisfaction, and negatively correlated with body mass index. To further examine the interplay between attempting to lose weight and restraint, three study groups were created: unrestrained nonattempters (21.5%, N = 20), unrestrained attempters (40.9%; N = 38), and restrained attempters (34.4%; N = 32). The three groups did not differ significantly on binge eating or other eating behaviors; however, significant differences were observed for weight concern, shape concern, and body dissatisfaction. Discussion: Attempts to lose weight and restraint are not synonymous for patients with BED. Although 75.3% of BED patients reported that they were attempting to lose weight, only 37.6% reported dietary restraint on at least half the days of the previous month. While restraint was negatively associated with body mass index, it was not related to binge eating or overeating. Our findings raise questions about prevailing models that posit restraint as a predominant factor in the maintenance of binge eating in BED. 相似文献

Overeating is a major contributing factor to obesity and related health complications. For women, in particular, negative emotions such as stress strongly influence eating behavior and bingeing episodes. Modeling this type of binge eating in rodents presents challenges: firstly, stress‐induced anorexia is commonly observed in rodents therefore a mild stressor is required in order to observe an orexigenic effect. Second, many studies report using calorie restriction to observe the required behavior; yet this does not necessarily reflect the human condition. Thus, the aim of this study was to develop a model of emotional stress‐induced bingeing independent of caloric restriction. Female and male C57BL/6J mice were divided into ad libitum (n = 20 per sex) and food‐restricted (n = 20 per sex) groups which were both further split into a control group and a group exposed to frustration stress (n = 10 per group). All mice were provided intermittent access to a highly palatable food in 2 cycles. At the end of each cycle the stress group was subjected to a 15‐minute frustration episode where highly palatable food was within the home cage but inaccessible. Both groups were then given free access for 15 minutes. Frustrated female mice from the ad libitum displayed binge‐like behavior compared with controls (P = .0001). Notably, this behavior was absent in males. Ovariectomy had no impact on binge‐like behavior. Collectively, these data validate a novel model of emotional stress‐induced binge eating specific to female mice which does not require caloric restriction and is not driven by ovarian hormones. 相似文献

Objective: For binge eating disorder (BED) to be accepted as a distinct diagnostic category in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition, it must be demonstrated that the criteria identify a diagnostic entity that is distinct from bulimia nervosa and obesity. This study examined the difference in total energy intake per day, patterns of energy intake throughout the day, and nutrient content of foods consumed in obese individuals who met the criteria for BED (on binge and non‐binge days) and those who did not. Research Methods and Procedures: Twenty women, 12 who met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for BED and 8 matched obese controls, participated in the study. All participants underwent six random 24‐hour dietary recall telephone interviews conducted by experienced interviewers using the Nutrition Data Software System. Results: The BED group ingested significantly more kilocalories on days when they had binge eating episodes than the obese control group on average. The BED group ate significantly more in the evening on binge days than their control group counterparts. There is some indication in the data that those with BED may be restricting caloric intake. Finally, data indicated that the BED group ate significantly more protein, carbohydrate, and fat on binge days than on non‐binge days. However, the proportion of kilocalories from each nutrient shifted on BED binge days compared with non‐binge days to favor consumption of fat over carbohydrates. Discussion: More research needs to be done to determine if these findings are reproducible. Then, the neurobiological underpinnings of these differences in nutrient intake patterns and nutrient selection can be studied to help to determine the biological basis of the disorder. 相似文献

Objective: To investigate the relationships between alexithymia and emotional eating in obese women with or without Binge Eating Disorder (BED). Research Methods and Procedures: One hundred sixty‐nine obese women completed self‐report questionnaires, including the Beck Depression Inventory, the State Trait Anxiety Inventory, the Stress Perceived Scale, the Dutch Eating Behaviour Questionnaire, and the Toronto Alexithymia Scale. The presence of BED, screened using the Questionnaire of Eating and Weight Patterns, was confirmed by interview. Results: Forty obese women were identified as having BED. BED subjects and non‐BED subjects were comparable in age, body mass index, educational level, and socioeconomic class. According to the Dutch Eating Behaviour Questionnaire, BED subjects exhibited higher depression, anxiety, perceived stress, alexithymia scores, and emotional and external eating scores than non‐BED subjects. Emotional eating and perceived stress emerged as significant predictors of BED. The relationships between alexithymia and emotional eating in obese subjects differed between the two groups according to the presence of BED. Alexithymia was the predictor of emotional eating in BED subjects, whereas perceived stress and depression were the predictors in non‐BED subjects. Discussion: This study pointed out different relationships among mood, alexithymia, and emotional eating in obese subjects with or without BED. Alexithymia was linked to emotional eating in BED. These data suggest the involvement of alexithymia in eating disorders among obese women. 相似文献

Binge eating disorder (BED) and night eating syndrome (NES) are putative eating disorders frequently seen in obese individuals. Data suggest that BED fulfills criteria for a mental disorder. Criteria for NES are evolving but at present do not require distress or functional impairment. It remains unclear whether BED and NES, as they are currently defined, are optimally useful for characterizing distinct patient subgroups. We propose that a distinction be made between “eating disorders” and “non‐normative” eating patterns without associated distress or impairment. Although non‐normative eating patterns may not be considered mental disorders, they may be very important in terms of their impact on body weight and health. More precise behavioral and metabolic characterization of subgroups with eating disorders and non‐normative eating behaviors has important implications for understanding the etiology, pathophysiology, and treatment of obesity. Ultimately, better understanding of the many pathways to increased energy intake may lead to targeted strategies for prevention of overweight and obesity in at‐risk individuals and populations. 相似文献

FOSTER, GARY D, DAVID B SARWER, THOMAS A WADDEN. Psychological effects of weight cycling in obese persons: A review and research agenda. This review summarizes studies on the psychological effects of weight cycling (i.e., weight loss and regain) in obese persons and proposes an agenda for future research on this topic. Among general psychological constructs, the current literature suggests that weight cycling is not associated with depression, other psychopathology, or depressogenic cognitive styles. Weight cycling is associated with decreased perceptions of health and well-being, although the clinical significance of this relationship is uncertain. Among weight- and eating-related constructs, weight cycling does not appear to be related to restraint, hunger, or personality traits associated with eating disorders. Weight cycling, however, does appear to be associated with clinically significant reductions in eating self-efficacy and weak but consistent increases in binge eating severity. Definitive conclusions about the presence or absence of the psychological consequences of weight cycling are premature, given the small number of studies, as well as a variety of methodological and interpretive concerns. A new generation of research is necessary to determine the extent and nature of the psychological sequelae of weight cycling. 相似文献

Objective: To examine the relationship between shame and the behavioral and attitudinal features of eating disorders in men and women diagnosed with binge‐eating disorder (BED). Research Methods and Procedures: Participants were 188 consecutively evaluated adults (38 men and 150 women) who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for BED. Participants were interviewed and completed a battery of measures assessing shame, behavioral and attitudinal features of eating disorders, and general psychological functioning. Results: Shame did not differ significantly by gender and was not associated with BMI or binge‐eating frequency. Shame was significantly associated with the attitudinal features of eating disorders, even after controlling for levels of depression and self‐esteem. When considered separately by gender and controlling for depression and self‐esteem, shame was associated with body dissatisfaction in men and with weight concern in women. Discussion: Men and women with BED, who presented for treatment, reported similar levels of shame. Overall, while shame was related to attitudinal features, the specific associations differed by gender. For men, shame was related to how dissatisfied they felt with their bodies, whereas for women, shame was associated with concerns about weight. Interestingly, shame was not related to BMI or binge‐eating frequency in men or women. These results provide preliminary support for self‐conscious emotions playing different roles in men and women with BED. 相似文献

Objective: To compare different methods for assessing the features of eating disorders in patients with binge eating disorder (BED). Research Methods and Procedures: A total of 47 participants with BED were administered the Eating Disorder Examination (EDE) Interview and completed the EDE‐Questionnaire (EDE‐Q) at baseline. A total of 37 participants prospectively self‐monitored their eating behaviors daily for 4 weeks and then completed another EDE‐Q. Results: At baseline, the EDE and the EDE‐Q were significantly correlated on frequencies of objective bulimic episodes (binge eating), overeating episodes, and on the dietary restraint, eating concern, weight concern, and shape concern subscales. Mean differences in the EDE and EDE‐Q frequencies of objective bulimic episodes and overeating were not significant but scores on the four subscales differed significantly, with the EDE‐Q yielding higher scores. At the 4‐week point, the EDE‐Q retrospective 28‐day assessment was significantly correlated with the prospective daily self‐monitoring records for frequency of objective bulimic episodes and the mean difference between the methods was not significant. The EDE‐Q and self‐monitoring findings for subjective bulimic episodes and objective overeating differed significantly. Discussion: In patients with BED, the three assessment methods showed some areas of acceptable convergence. 相似文献

Objective: To examine rates of self‐reported childhood maltreatment in extremely obese bariatric surgery candidates and to explore associations with sex, eating disorder features, and psychological functioning. Research Methods and Procedures: Three hundred forty (58 men and 282 women) extremely obese consecutive candidates for gastric bypass surgery completed a questionnaire battery. The Childhood Trauma Questionnaire was given to assess childhood maltreatment. Results: Overall, 69% of patients self‐reported childhood maltreatment: 46% reported emotional abuse, 29% reported physical abuse, 32% reported sexual abuse, 49% reported emotional neglect, and 32% reported physical neglect. Except for higher rates of emotional abuse reported by women, different forms of maltreatment did not differ significantly by sex. Different forms of maltreatment were generally not associated with binge eating, current BMI, or eating disorder features. At the Bonferonni‐corrected significance level, emotional abuse was associated with higher eating concerns and body dissatisfaction, and emotional neglect was associated with higher eating concerns. In terms of psychological functioning, at the Bonferonni‐corrected level, emotional abuse and emotional neglect were associated with higher depression and lower self‐esteem, and physical abuse was associated with higher depression. Discussion: Extremely obese bariatric surgery candidates reported rates of maltreatment comparable with those reported by clinical groups and roughly two to three times higher than normative community samples. Reported experiences of maltreatment differed little by sex and were generally not significantly associated with current BMI, binge eating, or eating disorder features. In contrast, maltreatment—notably emotional abuse and neglect—were significantly associated with higher depression and lower self‐esteem. 相似文献

Objective: Many overweight adolescents display elevated risk for the development of eating disorders, as seen in higher rates of weight/shape concerns and disordered eating behaviors, but the extent of impairment in this subset of high‐risk adolescents has not been explored. Research Methods and Procedures: Eighty‐one overweight adolescents (63% girls) presenting for an Internet‐based weight loss program were assessed at baseline using the Eating Disorder Examination Questionnaire, the Depression, Anxiety, and Stress Scale, and the Pediatric Quality of Life questionnaire. Adolescents who earned elevated scores on both the Weight Concern and Shape Concern subscales of the Eating Disorder Examination Questionnaire were considered at high risk for the development of eating disorders (56.8%). Results: Comparisons of high‐ and normal‐risk groups revealed that high‐risk adolescents reported higher levels of depression [F(3,76) = 5.75, p = 0.019], anxiety [F(3,76) = 5.67, p = 0.020], and stress [F(3,75) = 8.50, p = 0.005], and greater impairments in physical health [F(3,77) = 10.7, p = 0.002], emotional functioning [F(3,77) = 5.3, p = 0.024], and social functioning [F(3,77) = 10.0, p = 0.002]. There were no differences in school functioning [F(3,77) = 1.5, p = 0.219]. Among the high‐risk adolescents, over half (52.2%) reported binge eating at least once in the past month. Discussion: Results suggest that overweight adolescents at high risk for the development of eating disorders also experience elevated levels of negative affect, impairment in health‐related quality of life, and eating disturbances, although prospective data are needed to determine the directionality between eating disorder pathology and general psychopathology. Further research is warranted to evaluate whether behavioral weight loss interventions should be enhanced for this high‐risk subset. 相似文献

Objective: There is a controversial discussion in the literature as to whether individuals with subthreshold binge eating disorder (subBED) differ clinically significantly from individuals with full‐syndrome binge eating disorder (BED). This study was designed to compare eating‐related and general psychopathology at baseline and in response to a multimodal treatment program in obese people with subBED compared with BED. Research Methods and Procedures: A total of 96 obese participants (BMI ≥ 30 kg/m2) were assessed for eating‐related and general psychopathology at baseline. Thirty‐nine participants meeting criteria for BED and 19 participants meeting criteria for subBED attended a 15‐session outpatient group therapy including cognitive behavioral therapy extended by interpersonal therapy, nutritional counseling, and a supervised walking exercise. Participants with eating disorders were reassessed at the end of treatment and at 3‐month follow‐up. The obese control group without an eating disorder (n = 38) was assessed once. This was not a randomized controlled trial. Results: Intent‐to‐treat analyses revealed no differences between subBED and full‐syndrome BED participants with regard to eating‐related and general psychopathology at baseline and with regard to treatment outcome. All participants experienced substantial improvements, and the results remained stable during follow‐up (except for dietary restraint). At follow‐up, participants with subBED and BED remained different from non‐eating disorder controls in eating‐related but not general psychopathology. Discussion: The findings indicate that our multimodal treatment program is equally effective in obese subBED and BED participants, suggesting that a differentiation currently seems not to be of clinical significance. 相似文献

Objectives: To determine whether maternal attitude towards the family regularly eating together and maternal report of how often the family eat together are associated with adolescent offspring overweight. Research Methods and Procedures: A cross‐sectional mother‐child‐linked analysis was carried out using 14‐year follow‐up data from a population‐based prospective birth cohort of 3795 children (52% males) who were participants in the Mater‐University study of pregnancy, Brisbane, Australia. Maternal reports on family eating pattern reported at age 14 were used. Results: The prevalence of overweight at age 14 was 24.1% (95% confidence interval (CI), 22.3, 26.1) for males and 27.1% (CI, 25.1, 29.2) for females. The majority of mothers (78%) reported that the family ate together at least once a day, but only 43% reported that they felt that family eating together was important. The offspring of women who felt that the family eating together was not important had increased odds of being overweight at age 14 (odds ratio, 1.27; 95% CI, 1.05, 1.53) in age‐ and sex‐adjusted models. Adjustment for potential confounding factors had no substantive effect on the association. There was no association between maternal reports of how often the family actually did eat together and overweight at age 14 in the offspring. Discussion: These findings suggest that maternal attitude towards family eating patterns, but not maternal report of how often the family do eat together, are associated with childhood overweight status. Maternal attitude towards family eating (as opposed to a report of actual frequency at one time‐point) may reflect broader maternal influences (beyond family eating pattern) on their child's diet and eating patterns over a long time course. 相似文献

Objective: To examine the occurrence of binge eating and its impact on weight loss outcomes among obese participants in the Trevose Behavior Modification Program, a lay‐administered, lay‐directed self‐help weight loss program offering continuing care. Research Methods and Procedures: Participants completed questionnaires, and weight loss data were recorded prospectively. Results: Although objective bulimic episodes were reported by 41% of the sample, objective bulimic episodes were not associated with worse weight loss outcomes. Mean weight loss after 12 months was 18.2 kg (18.8% of initial body weight) for the treatment completers and 10.3 kg (10.5% of initial body weight) for the full sample (using intent‐to‐treat analyses, with baseline scores carried forward). Discussion: Substantial long‐term weight loss, resulting from a continuing care treatment program, occurred in individuals both with and without frequent binge eating. 相似文献

Objective: To examine binge-eating disorder (BED) and its association with obesity, weight patterns, and psychopathology in a Brazilian sample of female participants of a weight-loss program in São Paulo, Brazil. Research Methods and Procedures: Two hundred and seventeen overweight (body mass index ≥ 25 kg/m2) women, ages 15 to 59 years, enrolled in the Weight Watchers Program were recruited for the study at a program branch meeting after completing the Questionnaire on Eating and Weight Patterns–Revised, Beck Depression Inventory, and the Toronto Alexithymia Scale-20. Participants were categorized into four groups: those who met questionnaire criteria for BED, those who met questionnaire criteria for bulimia nervosa (BN), those that reported binge eating but did not meet all the criteria for any eating disorder (BE), and those with no eating disorder symptoms (No ED). Groups were compared on measures of weight, depressive symptoms, and alexithymia. Results: Binge eating was frequently reported by women in this study (BED, 16.1%; BN, 4.6%; BE, 22.6%). BED women had significantly higher body mass index, greater highest weight ever, and more frequent weight cycling than the No ED group. BED women also reported more depressive symptoms than BE and No ED women, and were more alexithymic than the No ED group. BE women presented more frequent weigh cycling and were also more depressed and alexithymic than the No ED group. Discussion: BED is not uncommon in overweight Brazilian women, and similar to North American and European samples, it is associated with overweight and higher levels of psychopathology in this population. 相似文献

[Purpose]
We obtained basic data on a proper weight loss training program by considering the relationship between body mass index (BMI), the perception of appearance, and eating attitudes of Korean female university students.[Methods]
The survey and anthropometry for the perception of appearance and eating attitudes were conducted targeting 657 female university students located in Seoul, Busan, Ulsan, Daejeon, Chungcheongnam-do, and Gangwon-do South Korea who were not specializing in physical education.[Results]
The underweight group accounted for 21.16% of the population, the normal weight group comprised 69.71%, the overweight group was 6.09%, and the obese group accounted for 3.04%. The satisfaction rate of appearance was 56.16%, the dissatisfaction rate was 43.84%, and normal-weight students who were dissatisfied with their own appearance comprised 48.5%. The More obese students were more dissatisfied with their appearance. As a result of investigating eating attitudes, 37.75% of all subjects had a risk for an eating disorder, and 38.6% were normal weight but showed a risk for an eating disorder. More obese (BMI) subjects were at higher risk for an eating disorder.[Conclusion]
The BMIs of the Korean female university students were lower than those of European and American Caucasian women students, but the dissatisfaction of Korean female university students with their appearances was greater than that of European and American students, indicating that more Korean female university students were suffering from an eating disorder. It is predicted that the incidence of eating disorders, such as anorexia and bulimia, will rise in Korean women if there is no accurate understanding and measure to identify the high risk group for an eating disorder. 相似文献20.
Objective: Food intake is known to be affected by macronutrient composition of the diet, and protein manipulation has been reported to alter food intake, but the effect of individual amino acids on eating behavior has not been fully studied. This study investigated the effect of diet supplementation with three individual amino acids on meal pattern in male rats. Research Methods and Procedures: Thirty‐two Sprague‐Dawley rats were randomly divided into four equal groups and fed control diet or histidine (5%)‐, leucine (5%)‐, or tyrosine (5%)‐supplemented diet for 2 weeks and were monitored for their meal pattern. Results: Total food intake and feeding rate of the different groups were not affected, although other components of meal pattern were altered. Histidine supplementation reduced diurnal meal size by 42% (p < 0.05), whereas that of leucine increased nocturnal meal size by ～35% (p < 0.05). Tyrosine supplementation increased food intake of the nocturnal period and decreased that of the diurnal period. Both histidine and tyrosine supplementation elevated fasting plasma insulin levels and suppressed fasting glucose significantly. Discussion: Individual amino acids were found to alter meal pattern differently. Further investigations are required to dissect the involvement of central and peripheral factors in these alterations. 相似文献
