Abstract
The Yale Food Addiction Scale (YFAS) operationalizes indicators of addictive-like eating, originally based on the Diagnostic and Statistical Manual of Mental Disorders 4th edition Text Revision (DSM-IV-TR) criteria for substance-use disorders. The YFAS has multiple adaptations, including a briefer scale (mYFAS). Recently, the YFAS 2.0 was developed to reflect changes to diagnostic criteria in the DSM-5. The current study developed a briefer version of the YFAS 2.0 (mYFAS 2.0) using the participant sample from the YFAS 2.0 validation paper (n = 536). Then, in an independent sample recruited from Mechanical Turk, 213 participants completed the mYFAS 2.0, YFAS 2.0, and measures of eating-related constructs in order to evaluate the psychometric properties of the mYFAS 2.0, relative to the YFAS 2.0. The mYFAS 2.0 and YFAS 2.0 performed similarly on indexes of reliability, convergent validity with related constructs (e.g. weight cycling), discriminant validity with distinct measures (e.g. dietary restraint) and incremental validity evidenced by associations with frequency of binge eating beyond a measure of disinhibited eating. The mYFAS 2.0 may be an appropriate choice for studies prioritizing specificity when assessing for addictive-like eating or when a briefer measurement of food addiction is needed.

Abstract
Increased obesity rates, an evolving food supply and the overconsumption of energy dense foods has led to an increase in research exploring addictive eating behaviours. This study aimed to investigate food addiction in a sample of Australian adults using the revised Yale Food Addiction Survey (YFAS) 2.0 tool and how it is associated with dietary intake, personality traits and mental health issues. Australian adults were invited to complete an online survey that collected information including: demographics, dietary intake, depression, anxiety, stress and personality dimensions including impulsivity, sensation seeking, hopelessness and anxiety sensitivity. A total of 1344 individuals were recruited with the samples comprising 75.7% female, mean age 39.8 ± 13.1 years (range 18–91 years) and body mass index BMI 27.7 ± 9.5. Food addiction was identified in 22.2% of participants using the YFAS 2.0 tool, which classified the severity of food addiction as “mild” in 0.7% of cases, “moderate” in 2.6% and “severe” in 18.9% of cases. Predictors of severe food addiction were female gender (odds ratio (OR) 3.65 95% CI 1.86–7.11) and higher levels of soft drink OR 1.36 (1.07–1.72), confectionary consumption and anxiety sensitivity 1.16 (1.07–1.26). Overall people with “severe” (OR 13.2, 5.8–29.8) or extremely severe depressive symptoms (OR 15.6, range 7.1–34.3) had the highest odds of having severe food addiction. The only variable that reduced the odds of having severe food addiction was vegetable intake. The current study highlights that addictive food behaviours are associated with a complex pattern of poor dietary choices and a clustering with mental health issues, particularly depression.

Abstract
Obesity is a global epidemic that contributes to a number of health complications including cardiovascular disease, type 2 diabetes, cancer and neuropsychiatric disorders. Pharmacotherapeutic strategies to treat obesity are urgently needed. Research over the past two decades has increased substantially our knowledge of central and peripheral mechanisms underlying homeostatic energy balance. Homeostatic mechanisms involve multiple components including neuronal circuits, some originating in hypothalamus and brain stem, as well as peripherally-derived satiety, hunger and adiposity signals that modulate neural activity and regulate eating behavior. Dysregulation of one or more of these homeostatic components results in obesity. Coincident with obesity, reward mechanisms that regulate hedonic aspects of food intake override the homeostatic regulation of eating. In addition to functional interactions between homeostatic and reward systems in the regulation of food intake, homeostatic signals have the ability to alter vulnerability to drug abuse. Regarding the treatment of obesity, pharmacological monotherapies primarily focus on a single protein target. FDA-approved monotherapy options include phentermine (Adipex-P®), orlistat (Xenical®), lorcaserin (Belviq®) and liraglutide (Saxenda®). However, monotherapies have limited efficacy, in part due to the recruitment of alternate and counter-regulatory pathways. Consequently, a multi-target approach may provide greater benefit. Recently, two combination products have been approved by the FDA to treat obesity, including phentermine/topiramate (Qsymia®) and naltrexone/bupropion (Contrave®). The current review provides an overview of homeostatic and reward mechanisms that regulate energy balance, potential therapeutic targets for obesity and current treatment options, including some candidate therapeutics in clinical development. Finally, challenges in anti-obesity drug development are discussed.

Abstract
Substance addiction (or drug addiction) is a neuropsychiatric disorder characterized by a recurring desire to continue taking the drug despite harmful consequences. Non-substance addiction (or behavioral addiction) covers pathological gambling, food addiction, internet addiction, and mobile phone addiction. Their definition is similar to drug addiction but they differ from each other in specific domains. This review aims to provide a brief overview of past and current definitions of substance and non-substance addiction, and also touches on the topic of diagnosing drug addiction and non-drug addiction, ultimately aiming to further the understanding of the key concepts needed for a foundation to study the biological and psychological underpinnings of addiction disorders.

Abstract
Both cigarette smoking and obesity are significant public health concerns and are associated with increased risk of early mortality. It is well established that the mesolimbic dopamine pathway is an important component of the reward system within the brain and is implicated in the development of addiction. Indeed, nicotine and highly palatable foods are capable of altering dopamine release within this system, engendering addictive like responses in susceptible individuals. Although additional research is warranted, findings from animal and human literature have elucidated many of neuroadaptions that occur from exposure to nicotine and highly palatable foods, leading to a greater understanding of the underlying mechanisms contributing to these aberrant behaviors. In this review we present the findings taken from preclinical and clinical literature of the known effects of exposure to nicotine and highly palatable foods on the reward related circuitry within the brain. Further, we compare the neurobiological and behavioral overlaps between nicotine, highly palatable foods and obesity. Lastly, we examine the stigma associated with smoking, obesity and food addiction, and the consequences stigma has on the overall health and wellbeing of an individual.

Abstract
Addictions, which are characterized by the inability to control a behavior despite existence of physical or psychological consequences, have biological, psychological and social determinants. Although the possibility of developing an addiction to some psychoactive substances (e.g. alcohol, tobacco, cannabis) and to gambling (i.e., gambling disorder) is now well demonstrated, the possibility to develop a non-drug addiction (i.e., behavioral addiction) to certain behaviors which provide pleasure (e.g. eating, having sex, buying things) is still in debate. The concept of food addiction, which refers to people who exhibit substance dependence criteria in relation to some high-fat and high-sugar foods, was recently proposed by applying substance dependence DSM criteria to eating behavior. To assess food addiction, the Yale Food Addiction Scale is now the only self-administered questionnaire (diagnosis and estimate of the number of symptoms of food addiction). Prevalence for food addiction is higher in overweight and obese patients, and in patients with certain psychopathological characteristics (i.e., depression, Attention Deficit Hyperactivity Disorder, high impulsivity), in patients who are single and in patients with neurobiological alterations in the reward system. However, it is still unclear whether food addiction is necessary associated with subsequent increase in body weight and/or obesity. An increasing number of studies demonstrated that drug addiction and food addiction shares some similar clinical, neurobiological and psychopathological and sociocultural risk factors. To test the pertinence to include food addiction as an addiction, it would be interesting to conduct future studies in patients who may experience harms related to their food addiction, including not only patients with obesity, but also patients with metabolic syndrome, type 2 diabetes, hypertension, dyslipidemia, atherosclerosis, stroke, or coronary heart disease. Food addiction is a clinical and multidimensional concept which requires integrated care with psychotherapy, pharmacological and social lines of approach. This concept has also practical implications in terms of prevention and public health (e.g., prevention, brief interventions, possible law enforcement regarding some kinds of food which could present some addictive properties).

Abstract
INTRODUCTION The two main objectives were to identify addictive-like eating in youth and determine the relationship between addictive-like eating, hedonic hunger, and psychological variables. METHOD A cross-sectional design was used. Each subject's objective heights and weights were measured. Subjects completed questionnaires about anxiety, depression, appetitive responsiveness, addictive-like eating, other forms of disordered eating, and exercise patterns. RESULTS Sixty-five children, ages 9 to 14 years, participated in the study. The mean body mass index percentile for age and gender was 69%. Thirty-eight percent of the children were either overweight or obese. Sixteen percent reported three or more addictive-like eating behaviors, and 4% met the criteria for "food addiction." Addictive-like eating was significantly correlated with appetitive responsiveness but not body mass index, anxiety, depression, or other measures of disordered eating. DISCUSSION Addictive-like eating occurs in children as young as 9 years and appears to be a different type of disordered eating. The hedonic value and proximity of food is a contributor to addictive-like eating behaviors.

Abstract
Scientific interest in "food addiction" is growing, but the topic remains controversial. One critique of "food addiction" is its high degree of phenotypic overlap with binge eating disorder (BED). In order to examine associations between problematic eating behaviors, such as binge eating and "food addiction," we propose the need to move past examining similarities and differences in symptomology. Instead, focusing on relevant mechanisms may more effectively determine whether "food addiction" contributes to disordered eating behavior for some individuals. This paper reviews the evidence for mechanisms that are shared (i.e., reward dysfunction, impulsivity) and unique for addiction (i.e., withdrawal, tolerance) and eating disorder (i.e., dietary restraint, shape/weight concern) frameworks. This review will provide a guiding framework to outline future areas of research needed to evaluate the validity of the "food addiction" model and to understand its potential contribution to disordered eating.

Abstract
The proposition of so-called 'food addiction' (FA) in the scientific literature has stimulated a recent surge in research and debate. The concept of FA is controversial, and opinion is divided. Many of the findings depend upon the use of a single instrument called the Yale Food Addiction Scale (YFAS). This review systematically examined FA, as defined by the YFAS, reported in 40 experimental human studies published in or after 2009. The results indicated that much of the literature makes the supposition that food addiction is an accepted neurobiological disease, consistent with substance use disorders; an interpretation based on very limited data. This raises the question as to whether those individuals who meet the YFAS criteria for diagnosis are truly 'addicted' to food or if they experience significant impairment to their psychological wellbeing and quality of life as would be expected in clinically recognised addictive disorders. At the present time, little research has investigated the extent to which a psychometric self-assessment of FA symptomatology can elucidate a harmful relationship with target foods in the diet. A positive YFAS diagnosis is usually positively associated with BMI and strongly linked with the presence of binge eating, but certain exceptions within the literature were revealed. Further clarification is required as to whether so-called FA is sufficiently different to existing conditions and traits to warrant classification as a distinctive disease phenotype rather than an expression of strong habits and preferences.

Abstract
There exists a continuous spectrum of overeating, where at the extremes there are casual overindulgences and at the other a 'pathological' drive to consume palatable foods. It has been proposed that pathological eating behaviors may be the result of addictive appetitive behavior and loss of ability to regulate the consumption of highly processed foods containing refined carbohydrates, fats, salt, and caffeine. In this review, we highlight the genetic similarities underlying substance addiction phenotypes and overeating compulsions seen in individuals with binge eating disorder. We relate these similarities to findings from neuroimaging studies on reward processing and clinical diagnostic criteria based on addiction phenotypes. The abundance of similarities between compulsive overeating and substance addictions puts forth a case for a 'food addiction' phenotype as a valid, diagnosable disorder.

Abstract
An increasing perspective conceptualizes obesity and overeating as disorders related to addictive-like processes that could share common neurobiological mechanisms. In the present study, we aimed at validating an animal model of eating addictive-like behavior in mice, based on the DSM-5 substance use disorder criteria, using operant conditioning maintained by highly palatable chocolate-flavored pellets. For this purpose, we evaluated persistence of food-seeking during a period of non-availability of food, motivation for food, and perseverance of responding when the reward was associated with a punishment. This model has allowed identifying extreme subpopulations of mice related to addictive-like behavior. We investigated in these subpopulations the epigenetic and proteomic changes. A significant decrease in DNA methylation of CNR1 gene promoter was revealed in the prefrontal cortex of addict-like mice, which was associated with an upregulation of CB1 protein expression in the same brain area. The pharmacological blockade (rimonabant 3 mg/kg; i.p.) of CB1 receptor during the late training period reduced the percentage of mice that accomplished addiction criteria, which is in agreement with the reduced performance of CB1 knockout mice in this operant training. Proteomic studies have identified proteins differentially expressed in mice vulnerable or not to addictive-like behavior in the hippocampus, striatum, and prefrontal cortex. These changes included proteins involved in impulsivity-like behavior, synaptic plasticity, and cannabinoid signaling modulation, such as alpha-synuclein, phosphatase 1-alpha, doublecortin-like kinase 2, and diacylglycerol kinase zeta, and were validated by immunoblotting. This model provides an excellent tool to investigate the neurobiological substrate underlying the vulnerability to develop eating addictive-like behavior.

Abstract
The Yale Food Addiction Scale (YFAS) is a widely used tool to assess the behavioural indicators of addictive-like eating. No studies, however, have used a longitudinal design to determine whether these addictive-like eating behaviours are a stable or transient phenomenon in a community-based population. This study aimed to evaluate whether food addiction Diagnosis and Symptom scores as assessed by the YFAS remain stable over 18-months in a non-clinical population. Young adults aged 18-35 years were recruited from the community to a web-based survey in 2013. The survey included demographics, anthropometrics and the YFAS. Participants who volunteered to be recontacted for future research were invited to complete the same survey 18-months later. The YFAS scoring outputs Diagnosis and Symptom scores were tested for agreement and reliability between the two time points. Of the 303 participants who completed the original survey and agreed to be recontacted, 69 participants (22.8% of those recontacted, 94% female, 67% normal weight at baseline) completed the 18-month follow-up survey. At baseline, thirteen participants met the YFAS predefined criteria for Diagnosis, while eleven participants met these criteria at the 18-month follow-up. YFAS Diagnosis was found to have moderate agreement [K = .50, 95% CI (.23, .77)] between the two time points while Symptom scores had good agreement [K = .70, 95% CI (.54, .83)]. Intraclass correlation coefficients were interpreted as moderate over the 18-month period for both the Diagnosis [ICC = .71, 95% CI (.45, .88)] and Symptom scores [ICC = .72, 95% CI (.58, .82)]. YFAS assessed food addiction Diagnosis and Symptom scores were found to be relatively stable over 18-months in a non-clinical population of predominantly female, young adults. Future research is required to determine the impact of behavioural weight loss interventions on YFAS assessed addictive-like eating.

Abstract
With the rising prevalence of obesity, hedonic eating has become an important theme in obesity research. Hedonic eating is thought to be that driven by the reward of food consumption and not metabolic need, and this has focused attention on the brain reward system and how its dysregulation may cause overeating and obesity. Here, we begin by examining the brain reward system and the evidence for its dysregulation in human obesity. We then consider the issue of how individuals are able to control their hedonic eating in the present obesogenic environment and compare 2 contrasting perspectives on the control of hedonic eating, specifically, enhanced control of intake via higher cognitive control and loss of control over intake as captured by the food addiction model. We conclude by considering what these perspectives offer in terms of directions for future research and for potential interventions to improve control over food intake at the population and the individual levels.

Abstract
This article looks at food addiction as a subject situated between psychiatry, neurobiology, nutritional science, internal medicine, food industry, and public health. Essentially, the question is whether or not individual nutritional components can induce physical dependence, similar to the well-known effects of drugs such as alcohol and cocaine, or whether food addiction is rather a behavioral addiction. The literature describes many overlaps as well as differences of substance-based and non-substance-based addiction in both clinical and neurobiological terms. Until recently it was argued that food addiction appears only in the realms of obesity and eating disorders (e.g., binge-eating disorder, BED). Some studies, however, described the prevalence of food addiction symptoms and diagnoses independent of overweight or that they were in subjects who do not fulfill the criteria for BED. This article sums up the controversial discussion about the phenomenological and neurobiological classification of food addiction. Implications of food addiction for children and adolescents as well as public-health-related issues are also discussed.

Abstract
INTRODUCTION Despite high rates of obesity in adolescents, little is known about their individual motives for eating caloric foods for reasons unrelated to hunger. The goal of this study was to provide a preliminary validation of the "Kids Palatable Eating Motives Scale" (K-PEMS), a self-report survey designed to identify individual motives for eating tasty foods in adolescents. The study also sought to determine if any specific motive(s) can account for variance in BMI and binge-eating disorder (BED) traits which can exacerbate obesity. METHODS BMIz and responses to the K-PEMS and the Children's Binge Eating Disorder Scale (C-BEDS) were obtained from inner-city low-income African American adolescents. Linear and logistic regressions were used to identify K-PEMS motives that were associated with greater BMIz and binge-eating traits. RESULTS The K-PEMS identified eating tasty foods for Social, Conformity, Reward Enhancement, and Coping motives. Higher frequency of eating tasty foods for Social and Conformity motives and lower frequency of eating these foods for Reward Enhancement accounted for 39% of the variance in BMIz among the overweight and obese adolescents. In contrast, eating for Coping motives was related to a 3-fold increase in the amended provisional criteria for BED in children which occurred in 7% of this young minority sample. DISCUSSION The K-PEMS can be used to identify adolescents' primary motives for eating tasty foods. These motives may provide early identification of obesity and binge-eating risk but more importantly, can be tailor-targeted to affect specific behavioral and/or cognitive changes to prevent these conditions in adulthood.

Abstract
Some forms of overeating closely resemble addictive behaviour. The Yale Food Addiction Scale (YFAS) was developed to measure such addiction-like eating in humans and has been employed in numerous studies for examining food addiction in adults. Yet, little is known about food addiction in children and adolescents. Fifty adolescents were recruited at the beginning of treatment in a weight-loss hospital and completed the YFAS among other questionnaires. Nineteen participants (38%) received a YFAS diagnosis, who did not differ in age, body mass and gender distribution from those not receiving a diagnosis. However, those with food addiction reported more binge days, more frequent food cravings, higher eating, weight and shape concerns, more symptoms of depression and higher attentional and motor impulsivity. Eating restraint and nonplanning impulsivity did not differ between groups. Results replicate findings from studies in obese adults such that food addiction is not related to age, gender, body mass or eating restraint, but to higher eating pathology, more symptoms of depression and higher impulsivity. Furthermore, results highlight that particularly attentional impulsivity is related to 'food addiction'. Addiction-like eating appears to be a valid phenotype in a substantial subset of treatment-seeking, obese adolescents.

Abstract
BACKGROUND Binge eating disorder (BED) is now a formal diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). However, post-DSM-5 patient profiles and viewpoints on BED diagnosis and treatment remain unclear. This study used a focus group methodology to examine demographic and clinical characteristics, as well as perceptions of diagnosis and treatment from patients with BED symptoms who were either formally diagnosed with BED or undiagnosed. METHODS Binge eating disorder-diagnosed individuals (n = 11) or those meeting the DSM-5 BED diagnostic criteria but were undiagnosed (n = 14) participated in 6 semistructured focus groups conducted by trained staff at 3 geographic locations in the United States. Patients completed a series of demographic and clinical measures and then engaged in a moderated discussion focused on identifying factors associated with their experiences with BED. RESULTS Sixty percent of the patients were female, 48% were white and 40% were black, and 76% were employed. The diagnosed group had a slightly higher socioeconomic status; undiagnosed patients had a higher average body mass index. In the overall sample, comorbid anxiety (40%) and depression (40%) were the most common psychiatric comorbidities. Even in the diagnosed group, only half of the patients (54.5%) became aware of BED through their health care provider (HCP; n = 6). Patients perceived that HCPs were focused more on physical ailments, were judgmental about weight, and were unable to distinguish BED from obesity. They also expressed a desire for safe, nonjudgmental interactions with HCPs. CONCLUSIONS Education and income may be factors affecting access to care and BED diagnosis. Both patient groups reported considerable psychopathology and medical comorbidities. Moreover, the patient groups perceived HCPs as both having inadequate understanding of BED and providing insensitive and ineffective communication regarding eating behaviors. The study findings in diagnosed and undiagnosed patient groups underscore the need for greater BED disease state awareness and patient sensitivity among HCPs.

Abstract
The purpose of this review is to familiarize readers with the role that addiction plays in the formation and treatment of obesity, type 2 diabetes and disorders of eating. We will outline several useful models that integrate metabolism, addiction, and human relationship adaptations to eating. A special effort will be made to demonstrate how the use of simple and straightforward nonlinear models can and are being used to improve our knowledge and treatment of patients suffering from nutritional pathology. Moving forward, the reader should be able to incorporate some of the findings in this review into their own practice, research, teaching efforts or other interests in the fields of nutrition, diabetes, and/or bariatric (weight) management.

Abstract
Obesity presents a major health hazard of the 21st century. It promotes co-morbid diseases such as heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Excessive energy intake, physical inactivity, and genetic susceptibility are main causal factors for obesity, while gene mutations, endocrine disorders, medication, or psychiatric illnesses may be underlying causes in some cases. The development and maintenance of obesity may involve central pathophysiological mechanisms such as impaired brain circuit regulation and neuroendocrine hormone dysfunction. Dieting and physical exercise offer the mainstays of obesity treatment, and anti-obesity drugs may be taken in conjunction to reduce appetite or fat absorption. Bariatric surgeries may be performed in overtly obese patients to lessen stomach volume and nutrient absorption, and induce faster satiety. This review provides a summary of literature on the pathophysiological studies of obesity and discusses relevant therapeutic strategies for managing obesity.

Abstract
Obesity is a global issue and it has been suggested that an addiction to certain foods could be a factor contributing to overeating and subsequent obesity. Only one tool, the Yale Food Addiction Scale (YFAS) has been developed to specifically assess food addiction. This review aimed to determine the prevalence of food addiction diagnosis and symptom scores, as assessed by the YFAS. Published studies to July 2014 were included if they reported the YFAS diagnosis or symptom score and were published in the English language. Twenty-five studies were identified including a total of 196,211 predominantly female, overweight/obese participants (60%). Using meta-analysis, the weighted mean prevalence of YFAS food addiction diagnosis was 19.9%. Food addiction (FA) diagnosis was found to be higher in adults aged >35 years, females, and overweight/obese participants. Additionally, YFAS diagnosis and symptom score was higher in clinical samples compared to non-clinical counterparts. YFAS outcomes were related to a range of other eating behavior measures and anthropometrics. Further research is required to explore YFAS outcomes across a broader spectrum of ages, other types of eating disorders and in conjunction with weight loss interventions to confirm the efficacy of the tool to assess for the presence of FA.

Abstract
With rising rates of obesity, research continues to explore the contributions of homeostatic and hedonic mechanisms related to eating behaviour. In this Review, we synthesize the existing information on select biological mechanisms associated with reward-related food intake, dealing primarily with consumption of highly palatable foods. In addition to their established functions in normal feeding, three primary peripheral hormones (leptin, ghrelin and insulin) play important parts in food reward. Studies in laboratory animals and humans also show relationships between hyperphagia or obesity and neural pathways involved in reward. These findings have prompted questions regarding the possibility of addictive-like aspects in food consumption. Further exploration of this topic may help to explain aberrant eating patterns, such as binge eating, and provide insight into the current rates of overweight and obesity.

Abstract
INTRODUCTION The contribution of an addictive process to elevated body mass index (BMI) and disordered eating is an area of growing interest. Yet, little is known about how "food addiction" may be related to disordered eating and obesity. The ability of addictive-like eating to account for eating pathology not captured by traditional eating disorders is unknown. No prior research has examined the association of "food addiction" with bulimia nervosa (BN). Finally, little is understood about the association of "food addiction" with patterns of dieting and weight gain. The current study was conducted to address these gaps in the literature. MATERIAL AND METHODS Participants (N=815) were recruited from online advertisements nationwide and completed measures related to "food addiction", BMI, weight history, and disordered eating. RESULTS Addictive-like eating was associated with elevated current and lifetime highest BMI, weight cycling, and eating pathology. The prevalence of "food addiction" was higher in participants with BN than in those with binge eating disorder (BED). "Food addiction" continued to be related to clinically relevant variables, especially elevated BMI, even when participants did not meet criteria for BED or BN. The co-occurrence of "food addiction" with eating disorders appears to be associated with a more severe variant of eating pathology. DISCUSSION An addictive-type response to highly palatable food may be contributing to eating-related problems, including obesity and eating disorders. BN relative to BED appears to be more strongly associated with "food addiction." Additionally, the concept of "food addiction" appears to capture clinically relevant information in participants who do not meet criteria for either BN or BED. Further examination of "food addiction" may be important in understanding the mechanisms underlying certain types of problematic eating behavior.

Some obese individuals report factors that drive overeating, including lack of control, lack of satiation, and preoccupation with food, which may stem from reward-related neural circuitry. These are normative and common symptoms and not the sole focus of any existing measures. Many eating scales capture these common behaviors, but are confounded with aspects of dysregulated eating such as binge eating or emotional overeating. Across five studies, we developed items that capture this reward-based eating drive (RED). Study 1 developed the items in lean to obese individuals (n = 327) and examined changes in weight over eight years. In Study 2, the scale was further developed and expert raters evaluated the set of items. Study 3 tested psychometric properties of the final 9 items in 400 participants. Study 4 examined psychometric properties and race invariance (n = 80 women). Study 5 examined psychometric properties and age/gender invariance (n = 381). Results showed that RED scores correlated with BMI and predicted earlier onset of obesity, greater weight fluctuations, and greater overall weight gain over eight years. Expert ratings of RED scale items indicated that the items reflected characteristics of reward-based eating. The RED scale evidenced high internal consistency and invariance across demographic factors. The RED scale, designed to tap vulnerability to reward-based eating behavior, appears to be a useful brief tool for identifying those at higher risk of weight gain over time. Given the heterogeneity of obesity, unique brief profiling of the reward-based aspect of obesity using a self-report instrument such as the RED scale may be critical for customizing effective treatments in the general population.

Abstract
BACKGROUND Both treatment of addiction and treatment of pediatric obesity often integrate the family unit. Thus, addiction therapies may provide a model to guide treatment of pediatric obesity, particularly issues of family communication, weight, and weight-related behaviors. The aim of this systematic review is to assess what knowledge in the field of addiction treatment can be translated to pediatric weight management, particularly in relation to family-based approaches and communication. METHODS A systematic review of family communication and food addiction in obese children was conducted using MEDLINE and other databases, including all English-language studies published after 1990 meeting search criteria and related to family factors or family communication, and addiction treatment strategies used in obesity interventions. RESULTS Three reviews, two survey studies, and two observational studies were included. Most focused on family communication; less-healthy communication patterns and parental restriction were related to maladaptive eating behaviors in children and attrition from weight management programs. A few studies suggested family communication interventions to improve unhealthy eating patterns in children, using therapies common in family treatment of addiction (e.g., motivational interviewing and cognitive behavioral therapy). No studies presented concrete suggestions to aid family communication around issues of food and weight management. Potential contributions of addiction therapies are discussed. CONCLUSIONS Though the addictive properties of food have not been fully delineated and obesity is not classified as a disease of addiction, the field of addiction offers many approaches that may prove useful in the treatment of obesity.

Abstract
Food has both homeostatic and hedonic components, which makes it a potent natural reward. Food related reward could therefore promote an escalation of intake and trigger symptoms associated to withdrawal, suggesting a behavioral parallel with substance abuse. Animal and human theoretical models of food reward and addiction have emerged, raising further interrogations on the validity of a bond between Substance Use Disorders, as clinically categorized in the DSM 5, and food reward. These models propose that highly palatable food items, rich in sugar and/or fat, are overly stimulating to the brain's reward pathways. Moreover, studies have also investigated the possibility of causal link between food reward and the contemporary obesity epidemic, with obesity being potentiated and maintained due to this overwhelming food reward. Although natural rewards are a hot topic in the definition and categorization of Substance Use Disorders, proofs of concept and definite evidence are still inconclusive. This review focuses on available results from experimental studies in animal and human models exploring the concept of food addiction, in an effort to determine if it depicts a specific phenotype and if there is truly a neurobiological similarity between food addiction and Substance Use Disorders. It describes results from sugar, fat and sweet-fat bingeing in rodent models, and behavioral and neurobiological assessments in different human populations. Although pieces of behavioral and neurobiological evidence supporting a food addiction phenotype in animals and humans are interesting, it seems premature to conclude on its validity.

Abstract
OBJECTIVES The goals of the present study were to explore the possibility that symptoms of food addiction may exist for some children and to identify factors that may be associated with pediatric food addiction. METHODS Participants were 50 children (aged 8-19), recruited from the Pediatric Lipid Clinic at a large southeastern teaching hospital, and their parent/guardian. Participants completed questionnaires to assess food- and eating-related attitudes and behaviors, as well as symptoms of food addiction. RESULTS Parent- and child-reported behaviors and attitudes demonstrated similar patterns. Child BMI ratings were significantly correlated with overeating (r = .42, p = .02) and emotional eating (r = .33, p = .04). Of note, 15.2% of children indicated that they "Often," "Usually," or "Always" think that they are addicted to food, and an additional 17.4% reported that they "Sometimes" feel that way. Food addiction symptoms were significantly correlated with child overeating (r = .64, p < .001), uncontrolled eating (r = .60, p < .001), emotionol eating (r = .62, p < .001), food preoccupation (r = .58, p < .001), overconcern with body size (r = .54, p < .001), and caloric awareness and control (r = -.31, p = .04). CONCLUSIONS Results of the present study suggest that "food addiction" may be a real problem for a subset of children who suffer from overweight/obesity. Identification of food addiction may improve obesity treatment efforts for this subset of patients.
