Unequivocally large, but not enormous: An examination of the nutritional content of objective and subjective binge-eating episodes using ecological momentary assessment data. Int J Eat Disord 2023; 56:1991-1997. [PMID: 37345531 PMCID: PMC10592441 DOI: 10.1002/eat.24016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 06/08/2023] [Accepted: 06/09/2023] [Indexed: 06/23/2023]
Abstract
OBJECTIVE This study compared the macronutrient profiles of subjective binge-eating episodes (SBEs), objective binge-eating episodes (OBEs), and typical eating episodes. METHOD Twenty-one adults with binge eating completed ecological momentary assessment of all eating episodes for 2 weeks, including detailed monitoring of food types and portions. Binge-eating episodes (N = 237) were coded as OBEs (n = 76) or SBEs (n = 161). Calories and macronutrients were computed using manufacturer information and USDA Food and Nutrient Database for Dietary Studies. Multilevel regression models compared the eating episode types on caloric and macronutrient content. RESULTS OBEs contained an average of 121.5 (95.1) g fat, 363.7 (289.1) g carbohydrates, 65.2 (38.2) g protein, 20.9 (16.4) g fiber, and 2856.2 (1869.2) calories. SBEs contained 31.6 (30.5) g fat, 76.5 (54.0) g carbohydrates, 20.5 (21.6) g protein, 5.3 (5.9) g fiber, and 695.1 (505.9) calories. Although OBEs contained significantly more calories and grams of all macronutrients than SBEs (p < .001), the macronutrient proportions of OBEs and SBEs did not differ. The proportions of carbohydrates (p = .005) and protein (p < .001) in SBEs significantly differed from typical eating episodes. DISCUSSION Our findings offer preliminary evidence that OBEs and SBEs are more comparable in macronutrient profile than typical eating episodes. PUBLIC SIGNIFICANCE STATEMENT The present study compared the calories and grams of macronutrients in objectively large binge-eating episodes, subjectively large binge-eating episodes, and typical meals and snacks. Results suggest that objectively and subjectively large binge-eating episodes demonstrate similar profiles of macronutrients, which are different from the macronutrient profile of meals and snacks. These results may help the eating disorder field better study the impact of subjectively large binge-eating episodes.

Abstract
BACKGROUND Binge eating is a subjective loss of control while eating, which leads to the consumption of large amounts of food. It can cause significant emotional distress and is often accompanied by purging behaviors (eg, meal skipping, overexercising, or vomiting). OBJECTIVE The aim of this study was to explore the potential of mobile sensing to detect indicators of binge-eating episodes, with a view toward informing the design of future context-aware mobile interventions. METHODS This study was conducted in 2 stages. The first involved the development of the DeMMI (Detecting Mental health behaviors using Mobile Interactions) app. As part of this, we conducted a consultation session to explore whether the types of sensor data we were proposing to capture were useful and appropriate, as well as to gather feedback on some specific app features relating to self-reporting. The second stage involved conducting a 6-week period of data collection with 10 participants experiencing binge eating (logging both their mood and episodes of binge eating) and 10 comparison participants (logging only mood). An optional interview was conducted after the study, which discussed their experience using the app, and 8 participants (n=3, 38% binge eating and n=5, 63% comparisons) consented. RESULTS The findings showed unique differences in the types of sensor data that were triangulated with the individuals' episodes (with nearby Bluetooth devices, screen and app use features, mobility features, and mood scores showing relevance). Participants had a largely positive opinion about the app, its unobtrusive role, and its ease of use. Interacting with the app increased participants' awareness of and reflection on their mood and phone usage patterns. Moreover, they expressed no privacy concerns as these were alleviated by the study information sheet. CONCLUSIONS This study contributes a series of recommendations for future studies wishing to scale our approach and for the design of bespoke mobile interventions to support this population.

Abstract
The objective of this review is to provide an updated synthesis of studies in individuals with eating disorders that examined the following components of binge eating episodes (BEEs): caloric intake, episode duration, and also the association of BEE size with psychopathology. A systematic review and meta-analysis were performed following the PRISMA guidelines. Searches were conducted on PubMed, PsycINFO, Scopus, SciELO, ScienceDirect and ProQuest databases. Meta-analysis was performed using random effects models and meta-regression. Forty-three studies were included. There was a paucity of information regarding BEE in individuals with anorexia nervosa. The pooled caloric intake of participants with bulimia nervosa (BN) during BEE in laboratory studies was significantly greater in comparison to the caloric intake during BEE in clinical studies [(3070 (95%CI 2596, 3544) vs. 1789 (95%CI 1498, 2081)], respectively. In participants with binge eating disorder (BED), the pooled means were 2088 (95%CI 1819, 2358) kcal in laboratory studies and 1903 (95%CI 1622, 2184) kcal in clinical studies, with no statistically significant difference between groups. Overall, BEE had a mean duration of 37.3 min in participants with BN and 41.7 min in those with BED. We found a positive correlation between the average caloric intake and level of depression (β = 55.5; p = 0.019). BEE in individuals with BN or BED were characterized by the consumption of extremely large quantities of calories. This was mainly found in laboratory studies of individuals with BN. BEE had a mean duration of less than 1 h in individuals with BN or BED. BEE size was positively associated with depression severity. Future research should explore the relevance of binge size as a core component of binge eating in clinical samples, in males, and in pediatric populations.

Abstract
In this study, we examined a structural equation model in which attachment anxiety and avoidance were associated with binge eating and restricted eating behaviors through distinct emotion regulation difficulties of emotional reactivity and emotional cutoff among college women ( n = 744) and men ( n = 200). As predicted, attachment anxiety was associated with emotional reactivity which, in turn, was associated with binge eating. Attachment avoidance was associated with emotional cutoff which, in turn, was associated with restricted eating, both in college women and men. Two gender differences were found: the association between emotional cutoff and binge eating was statistically significant only for women, and the association between emotional reactivity and binge eating was stronger for men than for women. Clinical implications are suggested, specifically the importance of addressing attachment insecurities and distinct emotion regulation difficulties related to serving college women and men with binge eating and/or restricted eating behaviors.

Abstract
Previous studies addressing the long-term impact of acceptance of food cravings have revealed positive effects in terms of reduced craving experience. The present study investigated the short-term (direct) consequences of acceptance-based craving regulation. Hungry participants were exposed to desirable food and were either instructed to accept or suppress food cravings during exposure. Control participants did not regulate cravings and were allowed to eat from the food. Participants who accepted food cravings reported a significant increase in food craving during the course of the experiment. Participants who suppressed their cravings during exposure kept their craving levels constant. In contrast, control participants who were allowed to eat from the food, reported a significant drop in cravings. These findings suggest that although acceptance may entail an effective strategy for reducing food cravings in the long run, it may require repeated practice to overcome the immediate counterproductive effects.

Abstract
BACKGROUND Objective binge eating episodes (OBEs) refer to binge eating on an unusually large amount of food and are the core symptom in current definitions of bulimia nervosa (BN) and binge eating disorder (BED). Subjective binge eating episodes (SBEs) refer to eating on a small or moderate amount of food (that is perceived as large) and like OBEs are associated with loss of control (LOC). Reaching consensus on what is considered a large amount of food can however be problematic and it remains unclear if the size of a binge is an essential component for defining a binge eating episode. The aim of this study was to compare the eating disorder features and general psychopathology of subjects reporting OBEs with those reporting only SBEs. METHODS This is a retrospective secondary analysis of data from 70 obese participants at the recruitment phase of a multicentre trial for BED. Individuals who answered positively to the presence of binge eating and LOC over eating had their binge eating episodes further explored by interview and self-report. Two groups, those who reported current OBEs (with or without SBEs) and those who reported current SBEs only were compared for age, gender, marital status, body mass index (BMI), indicators of LOC over eating, severity of binge-eating and associated psychopathology. RESULTS The majority of participants in both the OBE and SBE groups endorsed the experience of at least four indicators of LOC. There were no significant differences between the groups. Both groups had high levels of binge-eating severity, moderate severity of associated depressive symptoms and frequent psychiatric co-morbidity. CONCLUSION Treatment seeking participants with obesity who reported SBEs alone were similar to those who reported OBEs in terms of eating disorder features and general psychopathology. These findings suggest that classificatory systems of mental illnesses should consider introducing SBEs as a feature of the diagnostic criteria for binge eating and, thus, facilitate the inclusion of participants with SBEs in treatment trials.

Abstract
OBJECTIVE Binge eating, a cardinal symptom of bulimia nervosa (BN) and binge eating disorder (BED), continues to pose challenges in terms of its definition and thus construct validity and clinical utility. This article reviews the available empirical data that support or refute the current DSM-IV-TR defined characteristics of a binge episode. METHOD A systematic literature review was conducted using Medline/PubMed electronic database on DSM-IV-TR defined binge characteristics and associated attributes. RESULTS Data support the current DSM guidelines indicating that binge episodes typically occur in less than 2 h. Size of binge episodes has variability across BN and BED diagnostic groups. Loss of control (LOC) continues to be a core feature of binge eating. Negative affect is the most widely reported antecedent. Strikingly, little is known about binge episodes among individuals with anorexia nervosa-binge/purge subtype. DISCUSSION Available empirical evidence supports the current DSM duration and LOC attributes of a binge episode in BN and BED. However, a more controversial issues is the extent to which size is important in the definition of a binge episode (e.g., subjective vs. objective episodes) across diagnostic categories and the extent to which binge size informs prognosis, treatment, and clinical outcomes. Further study of binge eating attributes in AN is needed.

Abstract
OBJECTIVE Given limited data on the diagnostic validity of binge eating disorder (BED) in adolescents, this study sought to characterize overweight adolescents according to types of overeating episodes. METHOD Ninety-six adolescents (ages 13-17 years) with recurrent binge eating (BE), loss of control with or without overeating (subclinical BE; SUB), overeating without loss of control (OE), and no overeating or loss of control episodes (CONTROL) were compared on weight/shape concerns and depressive symptoms using ANCOVA and post-hoc least squares difference tests. RESULTS BE and SUB adolescents had higher weight/shape concern scores than OEs and CONTROLs (ps < .01). BE and SUB adolescents had higher depression scores than CONTROL adolescents (ps < .05). BE adolescents had greater depression scores than OE (p < .01) but not SUB adolescents. CONCLUSION Loss of control over eating signals increased impairment independent of overeating in adolescents. Results support refining BED criteria for youth to reflect this distinction.

Abstract
Disordered eating attitudes and behaviors appear to be quite common in youth, and overweight youth have been identified as a subset of the population at particularly high risk for endorsing such symptoms. Overweight and eating disorder (ED) symptomatology independently confer significant threats to one's physical and psychosocial health, showing strong links with body weight gain and risk for ED development. When concurrent, the risk for negative health outcomes may be compounded. The purpose of this article is to review the current state of the literature as it concerns disordered eating and its correlates in overweight children and adolescents. Extant literature on the prevalence, distribution, correlates, and etiology of disordered eating attitudes and behaviors (i.e., negative attitudes toward shape and weight, unhealthy weight control behaviors, and binge eating) in overweight youth is reviewed and consolidated in order to make assessment and treatment recommendations for healthcare providers. The current literature suggests that early detection of disordered eating in overweight youth should be a priority to provide appropriate intervention, thereby helping to slow the trajectory of weight gain and prevent or reduce the long-term negative consequences associated with both conditions. Future research should focus on explicating developmental pathways, and on developing novel prevention and treatment interventions for overweight youth exhibiting disordered eating patterns.

Abstract
This study compared maladaptive core beliefs of eating-disordered groups (full and subthreshold syndrome) and healthy controls and investigated the association between eating disorder symptoms and core beliefs. Participants were compared on self-report measures of core beliefs (YSQ) and eating disorder psychopathology (BITE). Anorexia nervosa (AN; both subtypes) and bulimia nervosa (BN) patients had significantly more core beliefs than healthy controls. Binge eating disorder (BED) patients had intermediate scores between AN and BN on the one hand and healthy controls on the other hand. No correlation was found between core beliefs and frequency of binge eating. Frequency of vomiting, laxative misuse and fasting was positively associated with all domains of core beliefs. Patients with eating disorders have some core beliefs which are not directly related to eating, weight or shape. Frequency of purging and fasting behaviors is associated with more severe maladaptive core beliefs. Our data demonstrate the importance of identifying purging and fasting as significant clinical markers.

Abstract
Bulimia nervosa is a psychiatric condition that affects many adolescent and young adult women. The disorder is characterized by bingeing and purging behavior and can lead to medical complications. Thus, patients with bulimia nervosa commonly present in the primary care setting. Physical and laboratory examinations reveal markers of bulimia nervosa that are useful in making the diagnosis. Treatment is beneficial, and outcomes of early intervention are good. This article discusses the history, presentation, and tools needed for recognizing and treating bulimia nervosa in primary care.

Abstract
OBJECTIVE Research has begun to challenge the idea that a large amount of food is a diagnostically relevant distinction in classifying binge eating. This study examined the relationship between both objective and subjective (i.e., feeling out of control while eating an appropriate amount of food) binge eating frequency and factor analytically derived measures of dieting and psychopathology. METHOD Participants were 40 women who were admitted for inpatient treatment for bulimia nervosa, anorexia nervosa, binge-purge type, or eating disorder not otherwise specified with binge-purge symptoms. RESULTS Controlling for subjective binge frequency, neither the psychopathology nor the dieting factors were related to objective binge frequency. Controlling for objective binge frequency, dieting, but not psychopathology, was related to subjective binge frequency. There was no correlation between frequency of subjective and objective binge eating. DISCUSSION The results are discussed in light of research on restrained eating. Implications for diagnosis and the role of loss of control in defining binge behavior are also discussed.

Abstract
OBJECTIVE Although laboratory experiments suggest that negative affect inductions potentiate the relation between dieting and disinhibited eating, little research has tested whether this finding generalizes to binge eating in the natural environment. Thus, we assessed whether negative affect moderated the relation between dieting and binge eating in a passive-observational study. METHOD This aim was addressed with longitudinal data from a community sample of adolescents (N = 631). RESULTS For females, dieting and negative affect predicted binge eating in cross-sectional and prospective analyses, but negative affect potentiated the relation between dieting and binge eating only in the cross-sectional analyses. Similar, but attenuated results were found for males. DISCUSSION Findings converge with those from laboratory studies in suggesting that negative affect moderates the relation between dieting and binge eating, but also imply that dieting and negative affect constitute independent risk factors for binge eating. The lack of prospective effects may suggest that the interactive relations have a short time lag or are difficult to detect prospectively.

Abstract
This study was designed to examine temporally proximal and remote antecedents as well as immediate and delayed consequences of binge eating behavior. Participants included 16 undergraduate females who reported engaging in binge eating at least two times per week and experiencing a sense of lack of control during binge eating episodes on the Questionnaire of Eating and Weight Patterns. Results indicated that the most frequent proximal antecedents to binge eating were negative emotions such as feeling depressed, angry, empty, hopeless, worried, or dissatisfied. The most frequent consequences of binge eating included relief from negative feelings and thoughts and decrease in hunger or craving. The results of this study suggest that the function of binge eating can be identified through assessment of antecedents and consequences with real time recording and retrospective reports. Treatment implications are discussed.

Abstract
This article reviews and critiques the eating behavior literature comparing the binge and non-binge-eating episodes of three populations of normal-weight women: bulimics, self-identified binge eaters, and non-eating-disordered women. The specific behaviors evaluated are number of calories consumed during different types of eating episodes, frequency of binge eating, number of eating episodes, rate of food consumption, the macronutrient composition of the food ingested, and context and duration of eating. Differences in these populations' eating behavior are analyzed in terms of their theoretical contribution. It is concluded that differences in the observed behavior of these groups are consistent with restraint theory, purge opportunity, and the forbidden foods hypothesis. Conversely, results do not support carbohydrate craving theory or a deficit in the satiety mechanisms of bulimics. Suggestions for future research are presented.

Abstract
In the present article, a learning model of binge eating is presented. It has been hypothesized that, parallel to drug intake, the craving and excessive food intake of binge eaters is cue controlled. Research in support of the model is reviewed and a series of predictions about clinical and non-clinical issues is derived from the model. Amongst other things, the model predicts that binge eating might be successfully treated with cue exposure and response prevention. Practical issues are discussed and preliminary pilot studies on cue exposure for bingers are reviewed.

Abstract
This study proposed to demonstrate a classically conditioned blood sugar decrease in humans and to clarify its relevance for binge eating. Six conditioning trials were run in healthy females. The conditioned stimulus (CS) was a compound peppermint flavor/fragrance, whereas the unconditioned stimulus (UCS) consisted of 50 g of oral glucose. Control subjects received an aspartame drink as the UCS. Ad lib glucose intake, blood parameters, and subjective craving were monitored before and after conditioning. Results showed that the experimental group failed to show conditioned blood sugar and glucagon decreases or C-Peptide increases. Although an increased insulin response was found in the experimental group, the effect size did not exceed that of spontaneous fluctuations. No increases in craving for sweet substances were found. An impressive increase (mean: 78%) in glucose intake after conditioning was found in both conditions, as well as in a subsequently run third condition with plain water as the UCS. The increased glucose intake probably resulted from an initial neophobia to the laboratory setting that subsided as subjects had experienced more lab sessions. Importantly, because no conditioned hypoglycemia occurred in the present study, its relationship with subjectively experienced craving for sweet substance could not be determined.

Abstract
Studies indicate that various measures of dietary restraint show inconsistent relations to bulimic symptomatology. The present study tested the assertion that this is because the scales differ in the extent to which they reflect the success or failure of dietary efforts. This study also tested the competing hypothesis that criterion confounding of the Restraint Scale produced the inconsistent findings. Data from 117 undergraduates indicated that both the Restraint Scale and the Dutch Restrained Eating Scale were correlated with bulimic pathology, but that the magnitude to the relations were higher for the former. These results supported the dietary success failure hypothesis, however, this difference disappeared when the two disinhibited eating items from the Restraint Scale were deleted. Thus, the inconsistent findings in prior research appear to be due to the criterion confounding of the Restraint Scale. Implications for the measurement of restraint are discussed.
