Abstract
Objective Food Addiction (FA) and other well-known risk behavior as substance misuse tend to co-occur and may share similar risk and protective factors. The aim of this study was to assess the association between the diagnosis/severity of FA and psychosocial domains typically related to risk behavior syndrome in a large, nationally representative community sample of Generation Z underage Italian students. Method The sample consisted of 8,755 students (3,623 from middle schools, 5,132 from high schools). A short version of the Yale Food Addiction Scale 2.0 was administered to evaluate FA. Risk and protective factors related to demographic, personality, behavior, and family variables were examined. Stepwise multivariate logistic and linear regressions were conducted. Results The prevalence of FA was 30.8%. Female gender, social anxiety and depression symptoms, social withdrawal risk, Internet gaming disorder, social media addiction, current substance use, social challenge engagement and experienced doxing boosted the chance of FA diagnosis, whereas eating fruit and vegetables, playing competitive sports and an average sleep duration of 7-8 h per night reduced these odds. FA severity was significantly and positively associated with trait impulsiveness, social anxiety and depressive symptoms, risk of social withdrawal, recent substance use, social media, and gaming addiction, doxing suffered and risky social challenges participation. Negative associations between the severity of FA and fruit and vegetable diet habits were found. Conclusion Our findings confirm that FA is widespread among Italian adolescents. The associations between the diagnosis and severity of FA and psychosocial risk factors for health, including, addictive and deviant behaviors related to digital misuse, suggest its belonging to the risk behavior constellation. Health promotion schemes based on a multicomponent strategy of intervention should consider the inclusion of FA and its psychosocial correlates.

Abstract
Binge eating demonstrates an evening diurnal shift among individuals with eating disorders. Disruptions to diurnal appetitive rhythms may be somewhat chronic and set the stage for additional disruptions to prompt binge eating. Despite known diurnal shifts in binge eating and related constructs (e.g., mood) and detailed characterizations of binge-eating episodes, no findings to date describe the naturalistic diurnal timing and composition of energy and nutrient intake on days with and without loss of control eating. We aimed to characterize eating behaviors (i.e., meal timing, energy intake, and macronutrient composition) across seven days in individuals with binge-spectrum eating disorders, assessing differences between eating episodes and days with and without loss of control eating. Undergraduate students (N = 51; 76.5% female) who endorsed past 28-day loss of control eating completed a 7-day naturalistic ecological momentary assessment protocol. Participants completed daily food diaries and reported instances of loss of control eating across the 7-day period. Results indicated that episodes of loss of control were more likely to occur later in the day, but overall meal timing did not differ across days with and without loss of control. Similarly, greater caloric consumption was more likely for episodes with loss of control, but overall caloric consumption did not differ between days with and without loss of control. Analysis of nutritional content demonstrated differences between both episodes and days with and without loss of control for carbohydrates and total fats, but not for protein. Findings provide support for the hypothesized role disruptions in diurnal appetitive rhythms play in maintaining binge eating via consistent irregularities, underscoring the importance of examining treatment adjuncts that intervene on the regulation of meal timing to enhance eating disorder treatment outcomes.

J Eat Disord 2021; 9:120. [PMID: 34583783 PMCID: PMC8479974 DOI: 10.1186/s40337-021-00475-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 09/10/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Studies on food cue reactivity have documented that altered responses to high-calorie food are associated with bulimic symptomatology, however, alterations in sexual motivations and behaviors are also associated clinical features in this population, which justify their inclusion as a research target. Here, we study responses to erotic cues-alongside food, neutral and aversive cues-to gain an understanding of specificity to food versus a generalized sensitivity to primary reinforcers. METHODS We recorded peripheral psychophysiological indices -the startle reflex, zygomaticus, and corrugator responses-and self-reported emotional responses (valence, arousal, and dominance) in 75 women completing the Bulimia Test-Revised (BULIT-R). Multiple regression analysis tested whether BULIT-R symptoms were predicted by self-reported and psychophysiological responses to food versus neutral and erotic versus neutral images. RESULTS The results showed that individuals with higher bulimic symptoms were characterized by potentiated eye blink startle response during binge food (vs. neutral images) and more positive valence ratings during erotic (vs. neutral) cues. CONCLUSIONS The results highlight the negative emotional reactivity of individuals with elevated bulimic symptoms toward food cues, which could be related to the risk of progression to full bulimia nervosa and thereby addressed in prevention efforts. Results also point to the potential role of reactivity to erotic content, at least on a subjective level. Theoretical models of eating disorders should widen their conceptual scope to consider reactivity to a broader spectrum of primary reinforcers, which would have implications for cue exposure-based treatments. We examined appetitive and aversive cue responses in college women to investigate how bulimic symptoms relate to primary reinforcers such as food and erotic images. We recorded peripheral psychophysiological indices (the startle reflex, zygomaticus, and corrugator responses) and self-reported emotional responses (valence, arousal, and dominance) in 75 college women that were presented with the Spanish version of the Bulimia Test-Revised. The results showed that bulimic symptoms increase both psychophysiological defensiveness toward food cues and subjective pleasure toward erotic cues. The findings suggest a generalized sensitivity to primary reinforcers in the presence of bulimic symptoms, and emphasize the relevance of adopting a wider framework in research and treatment on bulimia nervosa.

The FODRAT study (FOod addiction, DRugs, Alcohol and Tobacco): first data on food addiction prevalence among patients with addiction to drugs, tobacco and alcohol. Eat Weight Disord 2021; 26:449-455. [PMID: 32072572 DOI: 10.1007/s40519-020-00865-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 02/01/2020] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVES The main focus of this study was to evaluate the prevalence of food addiction (FA) in a population of 575 subjects, all affected by drugs, alcohol and/or tobacco addiction. METHODS Patients were enrolled in Addiction Service Centers and 25 items YFAS questionnaire was administered. Prevalence of FA was studied among patients who already have an addiction and then this prevalence was compared between groups of abusers (by type of substance), comparing mono abusers with polyabusers, as well as regressions by age, BMI, sex, through multiple regression analysis. RESULTS Prevalence of FA in the sample is 20.17%. Risk of FA increases with the number of substances used (polyabuse). Results show a positive correlation, in addicted people, between BMI values and FA, with significant values (OR 1.08; 95% CI 1.04-1.13; p = 0.006). Age is inversely correlated with FA (OR 0.97; 95% CI 0.95-0.99; p = 0.01). Female sex is positively associated (OR 2.60; 95% CI 1.59-4.27, p = 0.000). No significant association appears with any substance, even if the highest prevalence is recorded among cannabis users (31.03%), and heroin (21.07%), followed by cocaine (18.53%), alcohol (14.49%) and tobacco (11.61%). A comparison between the FA prevalence in our study and that from another study in the Italian general population (11%) shows a significant difference (p < 0.001). CONCLUSIONS Prevalence of FA among addicted people is greater than in the general population. Risk of FA increases with the increase in number of used substances (polyabuse). Age is inversely correlated with FA. There is a positive and significant correlation between BMI and FA among substance/tobacco abusers. LEVEL OF EVIDENCE Level V, observational cross-sectional descriptive study.

Abstract
The effectiveness of biofeedback and neurofeedback has been investigated in a range of psychiatric disorders. However, to date, there are few studies on the clinical usefulness of feedback-based techniques for eating disorders (EDs) and EDs-related symptoms (e.g., food craving). A systematic search of PubMed, Scopus and PsychINFO identified 162 articles. Among these, thirteen studies exploring the therapeutic use of biofeedback and neurofeedback in EDs or EDs-related symptoms were included. Biofeedback and neurofeedback were implemented respectively in five and eight of all reviewed articles. No studies incorporated different feedback modalities or both biofeedback and neurofeedback. The considered studies provide preliminary data of the usefulness of feedback-based techniques in the treatment of several dysfunctional eating behaviors (e.g., food craving, rumination). Although no significant effect has been reported for other important EDs-related symptoms (i.e., body image disturbance), feedback-based techniques are also associated with significant modifications of both sympathetic reaction to food-related stimuli and brain activity in several regions of the reward system (e.g., insula). Taken together the results of the present review suggest that feedback-based treatments may be useful in the treatment of several dysfunctional eating behaviors operating both on top-down and bottom-up individual coping strategies. Methodological and clinical issues are also discussed.

Abstract
OBJECTIVE The eating behavior of individuals with eating disorders has been examined in laboratory settings over the last 30 years. In this focused review, we build on prior research and highlight several feeding laboratory paradigms that have successfully demonstrated quantifiable and observable behavioral disturbances, and thereby add rigor and reproducibility to the examination of disturbances of eating behavior. This review describes the measures commonly obtained via these laboratory techniques. Supporting Information Appendices with detailed information about implementation are provided to allow for the reproducible execution of these techniques across labs. METHODS/RESULTS Literature documenting the existence of objective abnormalities in eating behavior among individuals with eating disorders or in comparison to healthy controls (n > 40) is briefly summarized. These protocols, conducted across at least 17 independent labs, are sensitive and reproducible, can be used to assess subjective and physiological parameters associated with eating, and elucidate the impact of treatment. Laboratory studies from patients with eating disorders compared with healthy controls reproducibly demonstrate both that patients with Anorexia Nervosa ingest fewer calories and that individuals with Bulimia Nervosa and Binge-Eating Disorder ingest more calories when asked to binge-eat. DISCUSSION Feeding laboratory studies have the potential for quantifying the characteristic behavioral psychopathology of patients with eating disorders, and may provide a useful tool to explore the potential utility of new treatments for individuals with Anorexia Nervosa, Bulimia Nervosa, and Binge-Eating Disorder.

A Protocol for a Quasi-Experimental, Cross-Sectional Design to Investigate Taste Aversion or Increased Hedonic Valence of Food in Eating Disorders. Front Psychol 2018; 9:264. [PMID: 29593595 PMCID: PMC5859071 DOI: 10.3389/fpsyg.2018.00264] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2017] [Accepted: 02/19/2018] [Indexed: 11/13/2022] Open
Abstract
Background: Despite on-going efforts to better understand dysregulated eating, the olfactory-gustatory deficits and food preferences in eating disorders (ED), and the mechanisms underlying the perception of and responses to food properties in anorexia nervosa (AN) and bulimia nervosa (BN) remain largely unknown; both during the course of the illness and compared to healthy populations. It is, therefore, necessary to systematically investigate the gustatory perception and hedonics of taste in patients with AN and BN. To this end, we will examine whether aversions to the taste of high-calorie food is related to the suppression of energy intake in restricting-type AN, and whether an increased hedonic valence of sweet, caloric-dense foods may be part of the mechanisms triggering binge-eating episodes in BN. In addition, the role of cognitions influencing these mechanisms will be examined. Method: In study 1, four mixtures of sweet-fat stimuli will be presented in a sensory two-alternative forced-choice test involving signal detection analysis. In study 2, a full-scale taste reactivity test will be carried out, including psychophysiological and behavioral measures to assess subtle and covert hedonic changes. We will compare the responses of currently-ill AN and BN patients to those who have recovered from AN and BN, and also to those of healthy normal-weight and underweight individuals without any eating disorder pathology. Discussion: If taste response profiles are differentially linked to ED types, then future studies should investigate whether taste responsiveness represents a useful diagnostic measure in the prevention, assessment and treatment of EDs. The expected results on cognitive mechanisms in the top-down processes of food hedonics will complement current models and contribute to the refinement of interventions to change cognitive aspects of taste aversions, to establish functional food preferences and to better manage food cravings associated with binge-eating episodes. No trial registration was required for this protocol, which was approved by the Swiss ethics committee (CER-VD, n° 2016-02150) and the Ethics Review Panel of the University of Luxembourg.

Abstract
BACKGROUND Health-related quality of life (HRQoL) in psoriasis patients could be negatively affected by medical (e.g., obesity) and psychological (e.g., depression, anxiety, and alexithymia) conditions the presence of which suggests difficulties in understanding and regulating inner states and emotions. Thus, the aim of this study was to investigate HRQoL and its association with obesity and difficulties in understanding and regulating inner states and emotions in patients with psoriasis. A second objective was to examine whether the presence of difficulties in understanding and regulating inner states and emotions may mediate the association between psoriasis and poor HRQoL. METHOD One hundred adult outpatients and 97 healthy controls were administered a checklist assessing major socio-demographic variables, and measures of HRQoL, difficulties in emotion regulation, alexithymia, anxiety, depression, and food craving. RESULTS Psoriasis patients (compared to controls) reported more frequently obesity, alexithymia, anxiety, depression and food craving, and reported lower scores on the mental and physical components of HRQoL. A mediation model, with mental health as the dependent variable, indicated significant direct and indirect (through BMI, difficulties in emotion regulation, anxiety, depression, and food craving) effects of psoriasis on the quality of life, so that psoriasis was associated with worse mental health. A second mediation model with physical health as dependent variable indicated only a significant indirect effect (through BMI and depression) of psoriasis on the quality of life. CONCLUSIONS Psoriasis is characterized by poor HRQoL and the presence of difficulties in understanding and regulating inner states and emotions. In patients with psoriasis the possible influence of food craving on abnormal eating habits should be carefully assessed.

Abstract
In the USA, binge eating disorder (BED) is the most common eating disorder, with a lifetime prevalence of ~3.5 % in adult women, 2.0 % in adult men, and 1.6 % in adolescents. BED is characterized by frequent episodes of binge eating that are accompanied by a sense of loss of control over eating and result in marked psychological distress. BED is highly co-morbid with obesity and with depression and other psychiatric conditions, and it is associated with substantial role impairment. Currently, there are no US FDA-approved pharmacological treatments for BED. Animal and human studies implicate underlying dysregulation in dopamine, opioid, acetylcholine, and serotonin neurocircuitry within brain reward regions in the pathogenesis and maintenance of BED. To date, the efficacy of various agents that target these and other neurotransmitter systems involved in motivated feeding behavior, mood regulation, and impulse control have been investigated in the treatment of BED. Several antidepressant and anticonvulsant agents have demonstrated efficacy in reducing binge eating frequency, but only in limited cases have these effects resulted in patients achieving abstinence, which is the primary goal of treatment; they also range from less (fluvoxamine) to more (topiramate) effective in achieving weight loss that is both clinically meaningful and significantly greater than placebo. Collectively, the literature on pharmacological treatment approaches to BED is limited in that very few agents have been studied in multiple, confirmatory trials with adequate follow up, and almost none have been evaluated in large patient samples that are diverse with respect to age, sex, and ethnicity. In addition, prior trials have not adequately addressed, through study design, the high placebo response commonly observed in this patient population. Several novel agents are in various phases of testing, and recent animal studies focusing on glutamate-signaling circuits linking the amygdala to the lateral hypothalamus offer new avenues for exploration and potential therapeutic development. Studies of newly FDA-approved medications for long-term obesity treatment and further explorations of dietary supplements and neutraceuticals with appetite- and mood-altering properties may also be worthwhile.

Abstract
Eating disorders are complex and serious psychiatric illnesses whose etiology includes psychological, biological, and social factors. Treatment of eating disorders is challenging as there are few evidence-based treatments and limited understanding of the mechanisms that result in sustained recovery. In the last 20 years, we have begun to identify neural pathways that are altered in eating disorders. Consideration of how these pathways may contribute to an eating disorder can provide an understanding of expected responses to treatments. Eating disorder behaviors include restrictive eating, compulsive overeating, and purging behaviors after eating. Eating disorders are associated with changes in many neural systems. In this targeted review, we focus on three cognitive processes associated with neurocircuitry differences in subjects with eating disorders such as reward, decision-making, and social behavior. We briefly examine how each of these systems function in healthy people, using Neurosynth meta-analysis to identify key regions commonly implicated in these circuits. We review the evidence for disruptions of these regions and systems in eating disorders. Finally, we describe psychiatric and psychological treatments that are likely to function by impacting these regions.

Hambly C, Speakman JR. Mice that gorged during dietary restriction increased foraging related behaviors and differed in their macronutrient preference when released from restriction. PeerJ 2015; 3:e1091. [PMID: 26157640 PMCID: PMC4493644 DOI: 10.7717/peerj.1091] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2015] [Accepted: 06/17/2015] [Indexed: 01/09/2023] Open
Abstract
Caloric restriction (CR) can trigger gorging behavior. We examined macronutrient choice and behavior in mice that gorged during restriction compared to restricted non-gorgers and controls. Fifty MF1 male mice were restricted to 75% of ad-libitum food intake (FI), while ten controls were fed ad-lib. Body mass (BM) and FI were measured two and 24-h after food inclusion over 14-days. ‘Gorging’ mice were defined as those which ate over 25% of their daily FI in 2-h. The top 11 gorgers and the lowest 9 gorgers, along with 10 controls, had their behavior analysed during restriction, and were then provided with an unrestricted food choice, consisting of three diets that were high in fat, protein or carbohydrate. During restriction gorgers ate on average 51% of their daily FI in the 2-h following food introduction while the non-gorgers ate only 16%. Gorgers lost significantly more BM than non-gorgers possibly due to an increased physical activity linked to anticipation of daily food provision. Controls and non-gorgers spent most of their time sleeping. After restriction, both gorgers and non-gorgers were hyperphagic until their lost weight was regained. All 3 groups favoured high fat food. Gorgers and non-gorgers had a significantly greater high carbohydrate diet intake than controls, and gorgers also had a significantly greater high protein diet intake than non-gorgers and controls. On unrestricted food, they did not continue to gorge, although they still had a significantly greater 2-h FI than the other groups. Elevated protein intake may play an important role in the recovery of the lost lean tissue of gorgers after restriction.

Abstract
PURPOSE The aim of the present study was to investigate dimensionality and psychometric properties of the Italian Food Cravings Questionnaire-Trait-reduced (FCQ-T-r) in a sample of obese and overweight patients seeking weight loss treatment. METHODS Participants were 504 (416 women and 88 men) overweight and obese patients (BMI ≥ 25 kg/m(2)), and 289 (215 women and 74 men) Italian adults not currently seeking weight loss treatment. All participants were administered the Food Cravings Questionnaire-Trait (FCQ-T) and the Binge Eating Scale. RESULTS The fifteen items included in the FCQ-T-r explained 93% of the variance of the 39-item FCQ-T total score (R(2) = 0.93). A principal axis factoring analysis indicated a one-factor solution, explaining 55.6% of the variance of the data. The FCQ-T-r had high internal consistency and was also able to differentiate between individuals with various severities of binge eating behavior. CONCLUSIONS The FCQ-T-r may be considered a useful instrument for measuring trait food craving, when time constraints impede the use of the 39-item FCQ-T.

Abstract
This case-control study examined gender differences in food craving among a sample of overweight and obese patients attending low energy diet therapy. To disentangle the specific role of gender from the role of confounders, we paired groups for BMI, age and severity of binge eating as assed by the Binge Eating Scale (BES). The participants were 73 pairs of patients who were attending low energy diet therapy. All the participants were administered the State and Trait Food Cravings Questionnaire, trait version (FCQ-T) and the BES. Female patients had higher mean scores on six out of nine dimensions of the FCQ-T. When controlling for the effect of other variables, obese and overweight female patients were 1.1 times more likely to report higher anticipation of relief of negative states and feelings from eating than their male pairs. Obese and overweight female patients experience more cravings for food than their male pairs despite comparable severity of binge eating and obesity suggesting the need for tailored interventions.

Abstract
OBJECTIVE Chromium treatment has been shown to improve mood, appetite, and glucose regulation in various psychiatric and medical patient populations. The authors propose that chromium may be useful in the treatment of binge eating disorder (BED). METHOD Twenty-four overweight adults with BED were enrolled in a 6-month double-blind placebo-controlled trial and randomly assigned to receive either 1000mcg chromium/day ("high dose"; n=8) or 600mcg chromium/day ("moderate dose"; n=9) as chromium picolinate or placebo (n=7). Mixed linear regression models were used to estimate mean change in binge frequency and related psychopathology, weight, symptoms of depression, and fasting glucose. RESULTS Fasting glucose was significantly reduced in both chromium groups compared to the placebo group; similarly, numerically, but not significantly, greater reductions in binge frequency, weight, and symptoms of depression were observed in those treated with chromium versus placebo, although statistical power was limited in this pilot trial. For fasting glucose, the findings suggest a dose response with larger effects in the high dose compared to moderate dose group. CONCLUSION These initial findings support further larger trials to determine chromium's efficacy in maintaining normal glucose regulation, reducing binge eating and related psychopathology, promoting modest weight loss, and reducing symptoms of depression in individuals with BED. Studies designed to link the clinical effects of chromium with changes in underlying insulin, serotonin, and dopamine pathways may be especially informative. If efficacious, chromium supplementation may provide a useful, low-cost alternative to or augmentation strategy for selective serotonin reuptake inhibitors, which have partial efficacy in BED.

Abstract
BACKGROUND Antipsychotic-induced weight gain is a problematic side effect. The mechanism is still not fully understood. Carbohydrate (and possibly other food) cravings have been suggested in literature, but not been systematically investigated. OBJECTIVES To investigate the hypothesis that food cravings, especially for carbohydrate, are responsible for olanzapine-induced weight gain. METHOD A case control design was used to measure general and specific food cravings using Food Craving Inventory (White et al., 2002) in three groups: patients with a diagnosis of schizophrenia taking olanzapine (Number = 20) or typical antipsychotics (Number = 20) and in a healthy control group (Number = 20). RESULTS No statistically significant differences were found between the three groups in the craving scores. There was a trend in the typical group to show more cravings than other groups. CONCLUSION Our study failed to prove the hypothesis that carbohydrate craving is responsible for olanzapine-induced weight gain. This conclusion is limited by the small number of the subjects included.

Abstract
This study examined how deprivation of chocolate affects state-level chocolate cravings, mood, and chocolate consumption in high and low trait-level chocolate-cravers. After identifying high and low chocolate cravers (N=58), half of the participants were instructed not to eat any chocolate for 2weeks. This created four experimental groups: deprived high-cravers (n=14), deprived low-cravers (n=14), non-deprived high-cravers (n=15), and non-deprived low-cravers (n=15). Following 2-week deprivation, state-level food cravings, mood, and chocolate intake were measured in a laboratory setting and compared across groups. Analyses revealed that anxiety increased over time for high-cravers (both deprived and non-deprived); state-level chocolate- and food-craving increased over time for both deprived groups and non-deprived high-cravers; non-deprived high-cravers ate the most chocolate; and, high-cravers were more joyful and guilty than low-cravers after eating chocolate in the laboratory. Theoretically, these results suggest that chocolate consumption may be better explained by trait-level of chocolate craving than by deprivation and highlighted significant differences in mood, state-level cravings, and chocolate intake between cravers and non-cravers following deprivation.

Abstract
BACKGROUND Craving or the "urge to consume" is a characteristic of bulimic eating disorders and addictions. Dysfunction of the dorsolateral prefrontal cortex (DLPFC) is associated with craving. We investigated whether stimulation of the DLPFC reduces food craving in people with a bulimic-type eating disorder. METHODS Thirty-eight people with bulimic-type eating disorders were randomly allocated to receive one session of real or sham high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left DLPFC in a double-blind procedure. Outcome measures included self-reported food craving immediately after the stimulation session and frequency of bingeing over a 24-hour follow-up period. RESULTS Compared with sham control, real rTMS was associated with decreased self-reported urge to eat and fewer binge-eating episodes over the 24 hours following stimulation. CONCLUSIONS High-frequency rTMS of the left DLPFC lowers cue-induced food cravings in people with a bulimic eating disorder and may reduce binge eating. These results provide a rationale for exploring rTMS as a treatment for bulimic eating disorders.

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
RATIONALE The long-rejected construct of food addiction is undergoing re-examination. OBJECTIVES To evaluate whether a novel carbohydrate food shows abuse potential for rigorously defined carbohydrate cravers, as evidenced by selective self-administration and mood enhancement during double-blind discrimination testing. MATERIALS AND METHODS Discrete trials choice testing was performed with 61 overweight (BMI m = 27.64, SD = 2.59) women (ages 18-45; 19.70% African American) whose diet records showed >4 weekly afternoon/evening emotional-eating episodes confined to snacks with carbohydrate to protein ratio of >6:1. After being induced into a sad mood, participants were exposed, double-blind and in counterbalanced order, to taste-matched carbohydrate and protein beverages. They were asked to choose and self-administer the drink that made them feel better. RESULTS Women overwhelmingly chose the carbohydrate beverage, even though blinded. Mixed-effects regression modeling, controlling for beverage order, revealed greater liking and greater reduction in dysphoria after administration of the carbohydrate beverage compared to the protein beverage but no differential effect on vigor. CONCLUSION For women who crave them, carbohydrates appear to display abuse potential, plausibly contributing to overconsumption and overweight.

Abstract
This is the first study to evaluate the psychometric properties of the Food Craving Questionnaire-Trait (FCQ-T), and Food Craving Questionnaire-State (FCQ-S) measures using a clinically heterogeneous sample of eating disorder patients (N = 177) recruited from seven different outpatient eating disorder treatment centers in Spain. Confirmatory factor analyses (CFAs) corroborated the factor structures of the FCQ-T and FCQ-S. The measures' scores and their factor-derived scale-scores yielded internal consistency reliability indexes that ranged from adequate to excellent. The measures were predictive of eating disorder symptoms. As expected, the FCQ-T was more strongly associated with eating disorder psychopathology than the FCQ-S. The results replicated the psychometric properties of the FCQ-T and FCQ-S in eating disorder populations and could become useful tools in clinical and research settings.

Abstract
The authors investigated the role of food incentive properties and homeostatic state on the motivational, anticipatory, and consummatory aspects of feeding. Behavioral tests were carried out on food-sated and food-restricted rats that were presented with 2 kinds of food differing in their palatability level. Both food-sated and food-restricted rats consumed large quantities and were highly motivated when presented with very palatable food. In contrast, only food-restricted rats developed anticipatory responses, regardless of the kind of food presented. These data suggest that food incentive properties play a key role in the control of consummatory and motivational components of feeding but seem less involved in the regulation of anticipatory behavior.

Abstract
OBJECTIVE To investigate energy expenditure and glucose metabolism after a standard oral glucose load (75 g) in 8 normal weight bulimic women and 8 normal weight control women and to evaluate the relative endocrine implication. DESIGN Serum glucose and insulin were measured both in basal conditions and after the glucose load; a basal endocrine assessment and body composition was evaluated and glucose induced thermogenesis (GIT) was calculated during 300 min following the glucose load. RESULTS Serum glucose levels were significantly lower in bulimics both in fasting and in post-prandial state. Insulin levels were similar in bulimic and control women before and after the glucose load. FSH, leptin and free urinary cortisol (FUC) were all within the normal ranges, but significantly lower in bulimic patients compared with controls (p < 0.001). Fat mass (FM) and Fat-free mass (FFM) were reduced in bulimic patients, even if they normalized after correction per body weight. Resting energy expenditure (REE) was similar in the two groups even after FFM normalization, while GIT was lower in bulimic patients and it was strongly related to free urinary chortisol. Glucose oxidation was higher in fasting state and post glucose load, while lipid oxidation was strongly reduced. CONCLUSION An energy preservation mechanism seems to be the key element for normal-weight bulimic patients' metabolism, consisting in leptin levels and GIT reduction, and lipid oxidation inhibition.

Development and validation of the food-craving inventory. Obesity Research, 10 (107-114)] in a group of obese patients with binge eating disorder (BED). METHOD Participants were 122 obese patients seeking treatment for BED who completed the FCI. Data from the original 28-item FCI were examined. The current study sample was then compared to a community sample of obese patients. RESULTS Confirmatory factor analysis confirmed the 4-factor structure of the FCI. An improved model was found following the deletion of 3 items, yielding a 25-item questionnaire. Secondary analyses indicated differences in patterns of food cravings between BED patients and an obese comparison group. DISCUSSION The current study confirmed the psychometric properties of the FCI for use with a group of treatment-seeking obese patients with BED. Collectively, the results imply that obese patients with BED may crave sweets to a heightened degree relative to other food classes.

Abstract
OBJECTIVE The current study tested the hypothesis that supplemental dietary protein would reduce binge eating frequency and test meal intake in women with bulimia nervosa (BN) or binge eating disorder (BED). METHOD Eighteen women with BN or BED ingested high-carbohydrate or high-protein supplements (280 kcal) three times daily over two 2-week periods. On the morning after each period, participants were given a high-protein or high-carbohydrate supplement (420 kcal) 3 hr before an ad libitum meal. RESULTS Binge eating episodes occurred less frequently during protein supplementation (1.12 episodes per week) than during carbohydrate supplementation (2.94 episodes per week) or baseline (3.01 episodes per week). Participants reported less hunger and greater fullness, and consumed less food at test meals, after protein than after carbohydrate (673 vs. 856 kcal). DISCUSSION Adding protein to the diets of women with BN and BED reduced food intake and binge eating over a 2-week period. These findings may have implications for the longer-term treatment of these disorders.

Abstract
OBJECTIVE Two experiments adopted a working memory approach to evaluate the effectiveness of visuospatial tasks as a technique for reducing food cravings. METHOD Dieting and non-dieting women were asked to form images of both food-related and nonfood items, induced by either pictures (Experiment 1) or verbal cues (Experiment 2). They were required to concurrently perform one of three tasks that load on the visuospatial sketch pad of working memory: saccadic eye movements, dynamic visual noise, or spatial tapping. RESULTS In support of the working memory model of limited visuospatial capacity, concurrent visuospatial activity reduced the vividness of food-related images which, in turn, reduced the intensity of the associated craving. The same pattern of results was observed across dieters and non-dieters and for all stimulus types. DISCUSSION Visuospatial tasks may provide a useful technique for the treatment of food craving episodes in both nonclinical and clinical populations.

Abstract
OBJECTIVE Dieting and stress are etiological factors in eating disorders, and dieting strongly predicts stress-induced overeating in the nonclinical population. We developed an animal model of binge eating in sated rats that is evoked by stress, but only in rats with a history of caloric restriction and only if highly palatable food (HPF) is available after stress. This study investigated the effect of known binge triggers, a taste of HPF and of hunger, on this type of binge eating. METHOD Female rats were cycled through the R/S protocol but this time were given just a taste of HPF with ad lib regular chow. After another R/S cycle, rats were stressed during restriction (while hungry) and were given HPF and chow. RESULTS Although binge eating did not occur if only chow was available after stress, just a taste of HPF sufficed to increase chow intake to more than 160% (p < 0.001) of rats with a history of restriction only, stress-only, or neither. Hunger increased the proportion of chow consumed by both restricted groups, but stress magnified this hunger-induced overeating by increasing HPF intake to 137% of restriction-only rats (p < 0.001). DISCUSSION These effects suggest that binge eating in this model is motivated by reward, not metabolic need, and parallels observations of binge triggers described in clinical binge-eating disorders. This strengthens the validity of using this animal model to target the physiology and treatment of eating disorders preceded by dieting and stress.

Abstract
BACKGROUND The clinical aspects of bulimia nervosa (BN) are similar in countries with different sociocultural backgrounds, but less is known about dietary composition in patients from developing countries. Little is also known about the role that nutritional aspects may play in behaviours aimed at counteracting the effects of binge eating. OBJECTIVES To describe the daily energy intake and eating behaviour of BN patients in Brazil and compare the dietary patterns of the patients who terminated eating episodes by vomiting and those patients who did not. METHODS Thirty patients from an eating disorders programme in a university-affiliated hospital completed a 14-day dietetic diary; the data were analysed using nutritional software. RESULTS Mean age and BMI of the patients were respectively 27.2 +/- 9.6 years and 25.5 +/- 6.7 Kg/m2. The patients in the vomiting subgroup ate more irregularly and consumed a more variable number of meals per day than those in the non-vomiting subgroup. The daily energy intake of the patients as a whole was 2,202 kcal, with a macronutrient composition of 53% carbohydrates, 31% fats and 17% proteins. The mean energy intake of the eating episodes followed by vomiting was 1,331 kcal with a macronutrient profile of 51% carbohydrates, 36% fat and 14% protein. Intake and eating patterns were characterised by between- and within- individual variability, and so no significant differences were found in the subgroup comparisons. Foods with a high energy density were preferred during the eating episodes followed by vomiting. CONCLUSIONS The results indicate that patients who vomit have a more irregular and variable eating pattern than those who do not vomit, but their daily nutrient content is comparable.

Abstract
Using confirmatory factor analysis, we cross-validated the factor structures of the Spanish versions of the State and Trait Food Cravings Questionnaires (FCQ-S and FCQ-T; ) in a sample of 304 Spanish college students. Controlling for eating disorder symptoms and food deprivation, scores on the FCQ-T were higher for women than for men, but no sex differences were observed on the FCQ-S. Eating disorder symptomatology was predictive of trait cravings, whereas food deprivation was predictive state cravings. Trait cravings, but not state cravings, were more strongly associated to symptoms of anorexia and bulimia nervosa than with other psychopathology. We suggest that cravings can be conceptualized as multidimensional motivational states and that our data support the hypothesis that food cravings are strongly associated with symptoms of bulimia nervosa.

Abstract
A alimentação e a dieta têm um importante papel no desenvolvimento e manutenção dos transtornos alimentares. Portanto, devem ser levados em consideração nos programas de tratamento dessas condições clínicas. Pacientes com transtornos alimentares apresentam importantes restrições dietéticas, padrões alimentares inadequados e hábitos errôneos devido a uma série de falsos mitos e crenças e a uma sensação de incompetência para lidar com o alimento. Tais alterações podem levar a mudanças em seu estado nutricional, que necessita de cuidados dietéticos específicos, como reabilitação nutricional e orientação sobre dieta adequada. Além disto, o aconselhamento nutricional é necessário para esclarecer e desmistificar crenças inadequadas e para estabelecer uma adequada relação com o alimento.

Abstract
OBJECTIVE We developed and tested the psychometric properties of Spanish versions of the Trait and State Food Cravings Questionnaires (FCQ-T and FCQ-S respectively). METHOD The instruments were translated and adapted to Spanish and administered to undergraduate students from a Southern university in Spain (N = 271). The data were analyzed using confirmatory factor analysis to compare the factor structure of the English and Spanish versions of both questionnaires. RESULTS The factors structure of both questionnaires obtained excellent fit indices across their Spanish versions with the one exception that some factors of the FCQ-S were more highly intercorrelated among the Spanish sample than the American. DISCUSSION This study supports the conceptualization of food cravings as universal multidimensional motivational states that can be reliably measured and supports the use of the Spanish versions of the FCQ.

Abstract
The goals of manual-based cognitive-behavioral therapy (CBT) and nutritional counseling for eating disorders are similar, namely, eliminating dysfunctional patterns of eating. Modifying these behaviors requires specific therapeutic expertise in the principles and procedures of behavior change that is not typically part of the training of nutritionists and dieticians or mental health professionals without specific expertise. We discuss ways in which principles of behavior change can be applied to eating disorders by non-CBT experts. Specific nutritional rehabilitation programs have the potential to augment CBT in addressing the array of appetitive abnormalities present in eating disorder patients. The dysfunctional appetitive, hedonic, and metabolic characteristics of patients with bulimia nervosa (BN) and binge eating disorder are reviewed. These abnormalities constitute potential target areas that might be more fully addressed by nutritional interventions designed to restore normal appetitive function.

Abstract
Although certain commonalities exist between eating and drug use (mood effects, external cue-control of appetites, reinforcement, etc. ), it is argued that the vast majority of cases of (self-reported) food craving and food "addiction" should not be viewed as addictive behavior. An explanation is proposed that instead gives a prominent role to the psychological processes of ambivalence and attribution, operating together with normal mechanisms of appetite control, the hedonic effects of certain foods, and socially and culturally determined perceptions of appropriate intakes and uses of those foods. Ambivalence (e.g., "nice but naughty") about foods such as chocolate arises from the attitude that it is highly palatable but should be eaten with restraint. Attempts to restrict intake, however, cause the desire for chocolate to become more salient, an experience that is then labelled as a craving. This, together with a need to provide a reason for why resisting eating chocolate is difficult and sometimes fails, can, in turn, lead the individual to an explanation in terms of addiction (e.g., "chocoholism"). Moreishness ("causing a desire for more") occurs during, rather than preceding, an eating episode, and is experienced when the eater attempts to limit consumption before appetite for the food has been sated.

Abstract
Binge eating is a consequence of semistarvation in victims of war and famine and in volunteers in rare semistarvation experiments. These behaviors include bizarre mixing of ingredients and adulteration of food; eating inappropriate, soiled, or discarded food; secrecy; deception; and defensiveness. Drastic measures to resist overeating persist long after the semistarvation experience, even when food is plentiful. Binge eating, a central feature of bulimia and sometimes of anorexia nervosa, is prevalent in modern society, but the occurrence and frequency of semistarvation-related behaviors have not been well identified or quantified. A Semistarvation-Associated Behaviors Scale was constructed and administered to 40 college students. Among binge eaters, reports of bizarre semistarvation-like behaviors were common and frequent and were associated with dieting.

Abstract
This study compared the satiating properties of three liquid lunches (450 kcal each), one dominant in protein (71.5% of energy), a second in carbohydrates (99% of energy) and a third containing an equal mixture of the first two formulations, in a within-subjects, repeated measures design. At an ad libitum dinner meal, 12 women consumed 31% more kilocalories in the high-carbohydrate lunch condition than in the high-protein lunch condition and 20% more kilocalories than in the mixture lunch condition. Similar results emerged for the amounts of protein and fat ingested at dinner. Subjects also reported significantly greater pre-dinner hunger and excitement about eating in the carbohydrate lunch condition than in the protein lunch condition. Greater enjoyment of dinner was also found after the carbohydrate lunch than after the mixture and protein lunches.

Abstract
This study investigated the effects of meals differing in macronutrient composition on subsequent food craving, bingeing, nutrient intake, and mood. Nine women who had prospectively demonstrated episodes of craving received one each of a high-protein, high-carbohydrate, and mixed meal on three separate days. Appetite and mood ratings were taken before and at four intervals up to 150 min after meal consumption. Subsequent ad libitum food intake was recorded in diaries. Premeal hunger, appetite and mood ratings were similar across meal type. After the protein-rich meal, craving for sweet, carbohydrate-rich foods was significantly higher than after the carbohydrate and mixed meals. Elevated negative mood state after the protein-rich meal and reduced vigor after the carbohydrate meal were not statistically significant. The first ad libitum eating episodes after the protein meal contained significantly higher absolute and proportional amounts of total carbohydrate and sucrose and were more likely to be categorized as a binge than were those after the carbohydrate and mixed meals. Those ad libitum eating episodes classified as a craving/binge were characterized by a higher energy and absolute carbohydrate, fat, and sucrose content. Evidence of macronutrient compensation after a protein-rich meal suggests that carbohydrate intake regulation may exist in certain individuals. Possibly via the effects of sensory-specific satiety, serotonergic function, or cognitive factors, a protein-rich meal may induce craving for sweet-tasting, palatable foods in susceptible individuals.

Abstract
Central injection of peptide YY (PYY) in sated rats produces the most powerful stimulating effect of food intake known to date. The neural mechanisms by which PYY regulates appetite are not clear but may be important because abnormal levels of PYY have been implicated in the neurobiology of bulimia nervosa. Interactions between brain acetylcholine (ACh) and PYY had not been studied. Therefore, the present experiments were designed to explore the in vivo release of ACh from the hippocampus (HPC) of rats in response to hypothalamic infusion of PYY. Hippocampal ACh release was found to increase 400% in response to 10 microg PYY. In a separate experiment, blockade of the same area of the HPC with bilateral intracerebral injections of 3.5 microg scopolamine did not affect intake stimulated by intrahypothalamic injection of 4 microg PYY. Furthermore, a third experiment showed, for the first time, that PYY (2.5-10.0 microg) can elicit robust feeding when infused directly into the HPC. The significance of these findings to the activation of limbic functions such as memory, reinforcement, and obsessional processes that accompany human binge-eating syndromes is discussed.

Abstract
The objective of the present study was to investigate the psychopathology and personality characteristics of women who experience food cravings. A total of 101 young women selected at random from the community completed the Diagnostic Interview for Genetic Studies with a trained interviewer. The interview included a section about food-craving experiences and associated factors. Subjects also completed a self-report questionnaire booklet containing the Temperament and Character Inventory (TCI) and the Eating Disorder Inventory (EDI). Compared to noncravers, women who reported food cravings were significantly more likely to report a history of alcohol abuse/dependence (p = .003), significant weight changes (p = .003), and to have undertaken dieting (p = .02), bingeing (p = .05), vomiting (p = .02), exercise (p = .04), diet pill (p = .03), and laxative use (p = .01) to control weight. There was a trend for the cravers to have higher novelty-seeking scores on the TCI (p = .06). Our findings suggest that women who experience food cravings are more likely to have met criteria for alcohol abuse/dependence and tend to have temperament characterized by higher levels of novelty seeking. In addition the high rates of eating-disorder symptomatology implies overconcern with body weight and shape in the women who experienced food cravings.

Abstract
OBJECTIVE The food selection and nutrient intake were investigated in women with anorexia nervosa, bulimia nervosa and controls. METHODS Dietary data was obtained by 24-hour recall, and 7-day recording among eating disordered patients, and by 3-day registration among controls. RESULTS The intake of energy and nutrients differed from controls, as expected, while there were no differences between anorectics and bulimics in this respect, except for iron. There were only minor differences among the three groups studied with respect to nutrient density. Energy percentages of protein, fat, and carbohydrates, were similar in all groups, but a subdivision of the macronutrients into respective sources showed that bulimics had a lower relative and absolute intake of carbohydrates from bread and cereals than anorectics and controls. CONCLUSION Eating disorder patients, despite their marginal food intake, still met the minimum requirement for most nutrients according to the Nordic Nutrient recommendations.
