BACKGROUND: Findings from studies of food addiction in adults suggest those with food addiction are less successful in weight-loss interventions. Little is known about food addiction in obesity treatment-seeking adolescents; therefore, the purpose of this study was to explore the prevalence of food addiction and correlates of food addiction symptoms in obese adolescents entering an outpatient, weight management program. METHODS: Obese adolescents (n = 26) were administered the Yale Food Addiction Scale for Children (YFAS-C), measures of appetitive responsiveness, and health-related quality of life (HRQOL) before and following a 12-week, outpatient, behavioral weight management program...

Non stabilized severe eating disorder is a contra-indication for bariatric surgery. Specific cares can stabilize this disorder, and therefore a surgery can be undertaken. In this respect, more and more attention is paid to the concept of food addiction even if its definition is still debated. Some authors, according to neurobiological data, consider food addiction as independent from eating disorder, but others see food addiction as a severe sub-type of eating disorder. To contribute to this debate, we performed a study in our department including 23 subjects candidates for a bariatric surgery and found a significant association between food addiction and eating disorder, independently of the body mass index...

(1) Background: With the new edition of the Diagnostic and Statistical Manual of Mental disorders, 5th Edition (DSM-5), numerous parallels have been drawn between recurrent binge eating (RBE) and substance use disorders, with many authors examining RBE or binge eating disorder (BED) as a "food addiction". The present study aims to clarify the relationship between recurrent binge eating (RBE) and illicit substance use (ISU) through investigating the temporal association between the two problems. (2) Methods: This study was embedded within a larger longitudinal study of non-clinical adult women recruited from Australian tertiary institutions...

Tobacco warning labels are important sources of risk information but research historically has been cigarette-centric. This qualitative study aimed to inform future direction and research on warnings for e-cigarettes. Between June and August 2016, we conducted interviews with 10 researchers with expertise in tobacco warning label research. Interviewees were registrants of a 2016 National Cancer Institute grantee meeting on tobacco warnings. Several participants agreed that the Food and Drug Administration's new nicotine addiction warning for e-cigarettes could be informative but that it might not resonate with young people...

The strong reinforcing effects of nicotine and the negative symptoms such as anxiety experienced during a quit attempt often lead to relapse and low success rates for smoking cessation. Treatments that not only block the reinforcing effects of nicotine but also attenuate the motivation to relapse are needed to improve cessation rates. Recent genetic and preclinical studies have highlighted the involvement of the α3, β4, and α5 nicotinic acetylcholine receptor (nAChR) subunits and the α3β4 nAChR subtype in nicotine dependence and withdrawal...

Polyunsaturated fatty acids (PUFAs) are lipid derivatives of omega-3 (docosahexaenoic acid, DHA, and eicosapentaenoic acid, EPA) or of omega-6 (arachidonic acid, ARA) synthesized from membrane phospholipids and used as a precursor for endocannabinoids (ECs). They mediate significant effects in the fine-tune adjustment of body homeostasis. Phyto- and synthetic cannabinoids also rule the daily life of billions worldwide, as they are involved in obesity, depression and drug addiction. Consequently, there is growing interest to reveal novel active compounds in this field...

BACKGROUND: Overeating and obesity are frequently attributed to an addiction to food. However, there is currently a lack of evidence to support the idea that certain foods contain any specific addictive substance. An alternative approach is to focus on dimensions of observable behaviour which may underpin a behavioural addiction to eating. To facilitate this, it is necessary to develop a tool to quantify addiction-like eating behaviour that is not based on the clinical criteria for substance-dependence...

Addressing healthcare costs requires incenting providers to address both physical and behavioral health conditions, as well as social determinants of health. The most complex, and expensive, patients are often those with comorbid mental illness and/or addiction, who are at higher risk for exposure to violence, food insecurity, unstable housing and other adversities that negatively affect health. Yet today's value-based payment models and associated quality measures do not incent providers to address patients' behavioral and social needs...

Cues in the environment can guide behavior in adaptive ways, leading one towards valuable resources such as food, water, or a potential mate. However, cues in the environment may also serve as powerful motivators that lead to maladaptive patterns of behavior, such as addiction. Importantly, and central to this article, there is considerable individual variation in the extent to which reward cues gain motivational control over behavior. Here we describe an animal model that captures this individual variation, allowing us to better understand the psychological and neurobiological processes that contribute to cue-evoked behaviors...

Obesity is taking up epidemic proportions worldwide with significant impacts on the health of both the affected individual and on society as a whole. Treatment approaches consist of behavioural and pharmacological approaches, however these are often found to be ineffective. In severe obesity, bariatric surgery is frequently performed. Unfortunately, 40% of patients show substantial weight gain over the long-term or display the associated metabolic syndrome, making the development of novel therapies necessary...

Impulsivity refers to a tendency to act rapidly without full consideration of consequences. The trait is thought to result from the interaction between high arousal responses to potential rewards and poor self-control. Studies have suggested that impulsivity confers vulnerability to both addiction and obesity. However, results in this area are unclear, perhaps due to the high phenotypic complexity of addictions and obesity. Focusing on impulsivity, the aim of this review is to tackle the putative overlaps between addiction and obesity in four domains: (1) personality research, (2) neurocognitive tasks, (3) brain imaging, and (4) clinical evidence...

Context • Weight loss and maintenance are associated with many health benefits, but long-term maintenance of weight loss remains elusive for many people. Overweight individuals are at higher risk than normal-weight individuals for stress-induced overeating. The use of stress-management tools in a weight loss program might decrease the physiological stress that fuels overeating and improve posttreatment maintenance of weight loss Objective • The study intended to compare the differences in outcomes between 2 approaches to achieving weight loss and changes in health-stress reduction and intuitive eating (IE)-during a 14-wk period...

INTRODUCTION: `The growth hormone secretagogue receptor 1a (GHS-R1a) is the orphan G-protein-coupled receptor, and its endogenous ligand is ghrelin. GHS-R1a contributes to regulation of glucose homeostasis, memory and learning, food addiction, and neuroprotection. Several PET tracers for GHS-R1a have been developed, but none have been reported to be clinically applicable to GHS-R1a imaging. In this study, we developed three new PET tracers for GHS-R1a: (18)F-labeled 6-(4-chlorophenyl)-3-((1-(2-fluoroethyl)piperidin-3-yl)methyl)-2-(o-tolyl)quinazolin-4(3H)-one (1), (11)C-labeled 6-(4-chlorophenyl)-3-((1-(2-methoxyethyl)piperidin-3-yl)methyl)-2-(o-tolyl)quinazolin-4(3H)-one (2), and (11)C-labeled (S)-(4-(1H-indole-6-carbonyl)-3-methylpiperazin-1-yl)(4'-methoxy-[1,1'-biphenyl]-4-yl)methanone (3)...

Physiological needs bias perception and attention to relevant sensory cues. This process is 'hijacked' by drug addiction, causing cue-induced cravings and relapse. Similarly, its dysregulation contributes to failed diets, obesity, and eating disorders. Neuroimaging studies in humans have implicated insular cortex in these phenomena. However, it remains unclear how 'cognitive' cortical representations of motivationally relevant cues are biased by subcortical circuits that drive specific motivational states. Here we develop a microprism-based cellular imaging approach to monitor visual cue responses in the insular cortex of behaving mice across hunger states...

A diversity of scales capture facets of reward-related eating (RRE). These scales assess food cravings, uncontrolled eating, addictive behavior, restrained eating, binge eating, and other eating behaviors. However, these scales differ in terms of the severity of RRE they capture. We sought to incorporate the items from existing scales to broaden the 9-item Reward-based Eating Drive scale (RED-9; Epel et al., 2014), which assesses three dimensions of RRE (lack of satiety, preoccupation with food, and lack of control over eating), in order to more comprehensively assess the entire spectrum of RRE...

Different parallel neural circuits interact and may even compete to process and store information: whereas stimulus-response (S-R) learning critically depends on the dorsal striatum (DS), spatial memory relies on the hippocampus (HPC). Strikingly, despite its potential importance for our understanding of addictive behaviors, the impact of drug rewards on memory systems dynamics has not been extensively studied. Here, we assessed long-term effects of drug- vs food reinforcement on the subsequent use of S-R vs spatial learning strategies and their neural substrates...

BACKGROUND: Weight regain is a common problem following weight loss intervention, with most people who seek treatment for obesity able to lose weight, but few able to sustain the changes in behavior required to prevent subsequent weight regain. The identification of factors that predict which patients will successfully maintain weight loss or who are at risk of weight regain after weight loss intervention is necessary to improve the current weight maintenance strategies. The aim of the present study is identify factors associated with successful weight loss maintenance by women with overweight or obesity who completed group cognitive behavioral treatment (CBT) for weight loss...

The concept of food addiction (FA) remains controversial with research being in the nascent stages; FA like any addiction can have a devastating impact on the lives of those afflicted. There exists a clinical need for treatment strategies for those affected. This article reviews potential treatment strategies for FA. The treatment strategies target four core behaviours of the addiction phenotype specifically craving through the opioid system, impulsivity as a personality trait, compulsivity through the serotonergic system and lastly motivation through the dopaminergic system...

OBJECTIVES: The potential role of an addictive process in problematic eating is a growing area of interest and debate. Children are more vulnerable to the negative effects of addictive substances than adults and may be at increased risk for addictive-like eating behavior. No prior study has evaluated the association of addictive-like eating with objectively measured eating behavior in adults or children. We examined the association between "food addiction" and observed food consumption among children and whether age moderated this association...
