Abstract
Background Anorexia nervosa (AN) is a mental and behavioral health condition characterized by an intense fear of weight or fat gain, severe restriction of food intake resulting in low body weight, and distorted self-perception of body shape or weight. While substantial research has focused on general anxiety in AN, less is known about eating-related anxiety and its underlying neural mechanisms. Therefore, we sought to characterize anxiety-to-eat in AN and examine the neurometabolic profile within the dorsal anterior cingulate cortex (dACC), a brain region putatively involved in magnifying the threat response. Methods Women seeking inpatient treatment for AN and women of healthy weight without a lifetime history of an eating disorder (healthy controls; HC) completed a computer-based behavioral task assessing anxiety-to-eat in response to images of higher (HED) and lower (LED) energy density foods. Participants also underwent magnetic resonance spectroscopy of the dACC in a 3 Tesla scanner. Results The AN group reported greater anxiety to eat HED and LED foods relative to the HC group. Both groups reported greater anxiety to eat HED foods relative to LED foods. The neurometabolite myo-inositol (mI) was lower in the dACC in AN relative to HC, and mI levels negatively predicted anxiety to eat HED but not LED foods in the AN group only. mI levels in the dACC were independent of body weight, body mass, and general anxiety. Conclusions These findings provide critical new insight into the clinically challenging feature and underlying neural mechanisms of eating-related anxiety and indicate mI levels in the dACC could serve as a novel biomarker of illness severity that is independent of body weight to identify individuals vulnerable to disordered eating or eating pathology as well as a potential therapeutic target.

Abstract
Studies have confirmed the link between altered dietary intake and eating disorders (EDs), although no systematic assessment of this research exists. Rigorous synthesis of dietary intake in anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and similar EDs is needed to explore similarities and differences. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we conducted a systematic review and quantitative synthesis of studies of dietary intake. Searches of three electronic databases resulted in thirty-nine included studies. Meta-analyses of subsets of these studies were undertaken to summarise macronutrient intake across AN, BN, and BED. Study quality was assessed using the American Academy of Nutrition and Dietetics Quality Criteria Checklist, with ratings either Positive (k = 27) or Neutral (k = 12). Adults with AN had low energy intake and those with BED reported elevated macronutrient intake. Individuals with BN reported wide variation in energy intake, including some of the highest estimates. Individuals with AN were likely to under-consume key micronutrients, with sodium potentially over-consumed in BN and BED. Vitamin D was under-consumed across all disorders. This meta-analysis highlights important diagnostic differences and synthesises dietary intake in EDs, with particular relevance to risk assessment and treatment.

Abstract
BACKGROUND Restriction of food intake is a central pathological feature of anorexia nervosa (AN). Maladaptive eating behavior and, specifically, limited intake of calorie-dense foods are resistant to change and contribute to poor long-term outcomes. This study is a preliminary examination of whether change in food choices during inpatient treatment is related to longer-term clinical course. METHODS Individuals with AN completed a computerized Food Choice Task at the beginning and end of inpatient treatment to determine changes in high-fat and self-controlled food choices. Linear regression and longitudinal analyses tested whether change in task behavior predicted short-term outcome (body mass index [BMI] at discharge) and longer-term outcome (BMI and eating disorder psychopathology). RESULTS Among 88 patients with AN, BMI improved significantly with hospital treatment (p < 0.001), but Food Choice Task outcomes did not change significantly. Change in high-fat and self-controlled choices was not associated with BMI at discharge (r = 0.13, p = 0.22 and r = 0.10, p = 0.39, respectively). An increase in the proportion of high-fat foods selected (β = 0.91, p = 0.02) and a decrease in the use of self-control (β = -1.50, p = 0.001) predicted less decline in BMI over 3 years after discharge. CONCLUSIONS Short-term treatment is associated with improvement in BMI but with no significant change, on average, in choices made in a task known to predict actual eating. However, the degree to which individuals increased high-fat choices during treatment and decreased the use of self-control over food choice were associated with reduced weight loss over the following 3 years, underscoring the need to focus on changing eating behavior in treatment of AN.

Abstract
OBJECTIVE Atypical anorexia nervosa (AN) has been increasingly identified in the community and in clinical settings. Initial studies indicate that psychological symptoms are similar or more severe among patients with atypical AN, as compared with AN. This study examined whether eating behavior differed among patients with AN (n = 98), patients with atypical AN (n = 18), and healthy controls (HC, n = 75). METHOD Adults and adolescents chose what to eat from a standardized, laboratory-based multi-item meal. Total intake, macronutrient composition, diet variety, and energy density were compared between groups. RESULTS Both AN and atypical AN severely restricted caloric intake as compared with HC (431 ± 396 kcal and 340 ± 338 kcal vs. 879 ± 350 kcal, F2,188 = 35.4, p < .001). Individuals with AN and atypical AN did not differ in the mean intake of total calories or percentage of calories from fat (15.2 ± 25.2% vs. 11.5 ± 16.9%). DISCUSSION This study demonstrates that individuals with atypical AN are at least as restrictive in their food intake as individuals with AN, and the restriction of dietary fat is particularly notable. Examination of eating behavior in a larger sample would be useful to replicate these findings. The current study highlights the need to understand maladaptive eating behavior in atypical AN in order to develop appropriate treatment recommendations. PUBLIC SIGNIFICANCE Atypical anorexia nervosa is emerging as a prevalent eating disorder in community and clinical populations. The findings that patients with atypical anorexia nervosa limit calorie and fat intake in a pattern similar to that of patients with anorexia nervosa highlights the need for research to identify appropriate treatment strategies for normalization of eating patterns.

Abstract
OBJECTIVE Eating disorders are characterized by disturbances in nutritional intake and abnormal mealtime behaviors. Laboratory eating paradigms offer a unique opportunity to accurately measure dietary intake and eating behaviors, however, these studies have predominantly occurred in adults. This paper describes the development and preliminary psychometric examination of the Buffet Challenge, a laboratory-based meal task for youths with an eating disorder. METHOD We recruited and assessed 56 participants as part of a randomized controlled trial of Family-Based Treatment for adolescents with anorexia nervosa. Adolescents completed the Buffet Challenge at baseline, midway through treatment (~ week 16 of a 6 months course), and end of treatment. Participants and their parents also reported eating disorder symptomatology and treatment related variables of interest were recorded. RESULTS All adolescents were willing to complete the Buffet Challenge at all time points, although one refused to give up their cellphone, and there were no significant adverse events recorded. Preliminary results are presented. CONCLUSIONS Our initial pilot of this task in adolescents with anorexia nervosa demonstrates its acceptability, although investigation of our hypotheses was hindered by significant missing data due to COVID-related research shutdowns. Future studies should replicate procedures in a larger sample to ensure analyses are adequately powered.

Abstract
PURPOSE Qualitative food avoidance is a significant issue in patients with anorexia nervosa (AN) and restoring diet diversity is an important part of the treatment process. We aimed to identify clinical factors which drive food avoidance and predict its maintenance in patients with AN. METHODS In this multicentre longitudinal study, 130 female outpatients with AN were assessed before and after 4 months of care in clinical centres specialized in AN. We assessed levels of avoidance of 16 food items, as well as body mass index (BMI), eating disorder severity, symptoms of depression and anxiety, emotional state, daily-life functioning, and body image perception. RESULTS We found that qualitative food avoidance was associated with the clinical severity of AN, anxiety and mood dimensions, and BMI- and body image-related factors. A younger age at onset predicted the maintenance of food avoidance after 4 months of treatment. Additional exploratory analyses suggested that anxiety and negative affect caused food avoidance more than the opposite. CONCLUSION Qualitative food avoidance can be an indicator of illness severity. During treatment, focusing on reducing anxiety and negative affect may be a way to indirectly reduce food avoidance and restore diet diversity. LEVEL OF EVIDENCE Level III: Evidence obtained from cohort or case-control analytic studies.

Abstract
Improvements in the clinical management of anorexia nervosa (AN) are urgently needed. To do so, the search for innovative approaches continues at laboratory and clinical levels to translate new findings into more effective treatments. In this sense, modern learning theory provides a unifying framework that connects concepts, methodologies and data from preclinical and clinical research to inspire novel interventions in the field of psychopathology in general, and of disordered eating in particular. Indeed, learning is thought to be a crucial factor in the development/regulation of normal and pathological eating behaviour. Thus, the present review not only tries to provide a comprehensive overview of modern learning research in the field of AN, but also follows a transdiagnostic perspective to offer testable explanations for the origin and maintenance of pathological food rejection. This narrative review was informed by a systematic search of research papers in the electronic databases PsycInfo, Scopus and Web of Science following PRISMA methodology. By considering the number and type of associations (Pavlovian, goal-directed or habitual) and the affective nature of conditioning processes (appetitive versus aversive), this approach can explain many features of AN, including why some patients restrict food intake to the point of life-threatening starvation and others restrict calorie intake to lose weight and binge on a regular basis. Nonetheless, it is striking how little impact modern learning theory has had on the current AN research agenda and practice.

Liver and vitamin B 12 parameters in patients with anorexia nervosa before and after short-term weight restoration. Psychiatry Res 2022; 314:114673.

Abstract
Hepatic involvement in anorexia nervosa (AN) has been previously reported, but a link to elevated vitamin B12 concentrations, which can be a sign for liver damage, has not been thoroughly examined. We measured liver enzymes (alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase) and vitamin B12 parameters (total B12, holotranscobalamin, methylmalonic acid) in the plasma of young female patients with acute AN (n=77) and after short-term weight restoration (n=58, median body mass increase=25%), in comparison to healthy control participants (n=63). For a comprehensive assessment of vitamin B12 status, the combined marker cB12 was calculated. In acute AN, activities of alanine aminotransferase and gamma-glutamyltransferase as well as holotranscobalamin concentrations were elevated, and alanine aminotransferase activities positively correlated with total B12, holotranscobalamin and cB12 in patients with elevated liver enzyme activities. After weight restoration, alanine aminotransferase activities and holotranscobalamin concentrations were elevated, and cB12 increased above the level of the healthy control group. The present study provides further evidence for a hepatic involvement in acute AN in concert with vitamin B12 parameters and points to refeeding-associated alterations of liver and vitamin B12 parameters. Future studies should include non-invasive methods to characterize hepatic involvement and evaluate vitamin B12 status as a potential marker of liver damage/irritation.

Abstract
BACKGROUND Pursuing a healthy diet is not a dysfunctional behavior, but dieting could be an important etiological factor for Orthorexia Nervosa (ON). The aim of this study was to investigate the role of diet in groups with high/low orthorexic tendencies. Moreover, some psychopathological characteristics associated with ON and maladaptive personality traits were investigated. METHODS The sample consisted of three groups: two were on a diet and had high (HIGH-D; n = 52) or low (LOW-D; n = 41) orthorexic tendencies. The other was composed of people with high orthorexic tendencies not on a diet (HIGH; n = 40). Participants filled out self-report questionnaires to investigate orthorexic tendencies, eating disorders features, obsessive-compulsive symptoms, perfectionism, depressive/anxious symptomatology, and maladaptive personality traits. RESULTS The HIGH-D group showed more orthorexic tendencies than the HIGH group. More maladaptive personality traits and anxiety symptoms have been highlighted in HIGH and HIGH-D groups. The HIGH group had more eating disorder characteristics than other groups. Only the HIGH-D group showed more depressive symptoms than the LOW-D group. CONCLUSIONS The features of HIGH and LOW-D groups suggest that diet alone could not explain ON, even if it could be a possible factor related to ON. Therefore, people with high orthorexic tendencies, psychopathological features, and maladaptive personality traits could be in a prodromic condition for disordered eating habits and deserve clinical attention.

Abstract
Decisions about what to eat recruit the orbitofrontal cortex (OFC) and involve the evaluation of food-related attributes such as taste and health. These attributes are used differently by healthy individuals and patients with disordered eating behavior, but it is unclear whether these attributes are decodable from activity in the OFC in both groups and whether neural representations of these attributes are differentially related to decisions about food. We used fMRI combined with behavioral tasks to investigate the representation of taste and health attributes in the human OFC and the role of these representations in food choices in healthy women and women with anorexia nervosa (AN). We found that subjective ratings of tastiness and healthiness could be decoded from patterns of activity in the OFC in both groups. However, health-related patterns of activity in the OFC were more related to the magnitude of choice preferences among patients with AN than healthy individuals. These findings suggest that maladaptive decision-making in AN is associated with more consideration of health information represented by the OFC during deliberation about what to eat.SIGNIFICANCE STATEMENT An open question about the OFC is whether it supports the evaluation of food-related attributes during deliberation about what to eat. We found that healthiness and tastiness information was decodable from patterns of neural activity in the OFC in both patients with AN and healthy controls. Critically, neural representations of health were more strongly related to choices in patients with AN, suggesting that maladaptive overconsideration of healthiness during deliberation about what to eat is related to activity in the OFC. More broadly, these results show that activity in the human OFC is associated with the evaluation of relevant attributes during value-based decision-making. These findings may also guide future research into the development of treatments for AN.

Abstract
Oxidative stress appears to be involved in the pathogenesis of osteoporosis-a serious complication of anorexia nervosa (AN). We evaluated the oxidative status in adolescent girls with AN and its potential relationship with bone mineral density (BMD). Girls with AN (n = 43) and age-matched healthy controls (n = 20) underwent anthropometric and BMD examination. Markers of bone turnover, oxidative stress, and antioxidant status were measured. Participants with AN and controls did not differ in BMD at the lumbar spine (p = 0.17) and total body less head BMD (p = 0.08). BMD at the total hip was lower (p < 0.001) in the AN group compared with the controls. Levels of antioxidant status markers-ferric reduction antioxidant power, total antioxidant capacity, and reduced and oxidized glutathione ratio (all p < 0.001)-were significantly lower, whereas those of advanced oxidation protein products (AOPP), fructosamines, and advanced glycation end products (AGEs) (all p < 0.001) were higher in AN patients than in healthy controls. BMD and bone turnover markers were positively correlated with antioxidant status markers, while they were negatively correlated with AOPP, fructosamines, and AGEs levels. Conclusion: This is the first study to assess a potential association between oxidative status and BMD in adolescents with AN. We demonstrated that in young girls, the imbalance of oxidative status and reduced BMD are concurrently manifested at the time of the diagnosis of AN. Disturbance of oxidative status could play a pathogenetic role in AN-associated decreased BMD. What is Known: • Osteoporosis is a serious complication of AN, and in affected adolescents may result in a permanent deficit in bone mass. • Oxidative and carbonyl stress may be involved in the development of bone loss. What is New: • Adolescents girls with AN have impaired antioxidant defense and increased oxidative damage to biomolecules. • Disturbance of oxidative status could affect bone loss and could contribute to decreased BMD in adolescent females with AN.

Impact of high energy oral nutritional supplements consumed in the late afternoon on appetite, energy intake and cardio-metabolic risk factors in females with lower BMI. Eur J Clin Nutr 2022; 76:811-818. [PMID: 34773094 PMCID: PMC9187517 DOI: 10.1038/s41430-021-01042-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 10/11/2021] [Accepted: 10/20/2021] [Indexed: 12/04/2022]
Abstract
BACKGROUND/OBJECTIVE Morning consumption of a single dose of high-energy oral nutritional supplement (ONS) in females with a lower BMI displaces some of the food eaten at breakfast but increases overall daily energy intake. This study investigated the effectiveness of ONS intake in the late afternoon and for longer duration. SUBJECTS/METHODS Twenty-one healthy females (mean ± SD, age 25 ± 5 years; BMI 18.7 ± 1.2 kg/m2) participated in a randomised, crossover study with two experimental trials. In the afternoon of days 1-5, participants consumed either ONS (2.510 MJ) or low-energy PLACEBO drink (0.377 MJ) and recorded food eaten at home. On day six, energy intake was measured during buffet meals, and energy expenditure, appetite measurements and blood samples were collected throughout the day. RESULT Over the 5-day period, in the ONS trial energy intake from evening meals was lower (ONS, 2.7 ± 0.25 MJ; Placebo, 3.6 ± 0.25 MJ, P = 0.01) but averaged total daily energy intake was higher (ONS, 9.2 ± 0.3 MJ; PLACEBO, 8.2 ± 0.4 MJ, P = 0.03). On day six, energy intake, appetite scores, plasma GLP-1 and PYY, and energy expenditure were not significantly different between the two trials but fasting insulin concentration and HOMAIR, were higher (P < 0.05) and insulin sensitivity score based on fasting insulin and TAG lower (P < 0.05) in ONS trial. CONCLUSION Late afternoon consumption of ONS for five consecutive days by females with a lower BMI has only a partial and short-lived energy intake suppression and thus increases daily energy intake but reduces insulin sensitivity.

Abstract
Eating disorders are potentially life-threatening mental health disorders that require management by a multidisciplinary team including medical, psychological and dietetic specialties. This review systematically evaluated the available literature to determine the effect of including a dietitian in outpatient eating disorder (ED) treatment, and to contribute to the understanding of a dietitian’s role in ED treatment. Six databases and Google Scholar were searched for articles that compared treatment outcomes for individuals receiving specialist dietetic treatment with outcomes for those receiving any comparative treatment. Studies needed to be controlled trials where outcomes were measured by a validated instrument (PROSPERO CRD42021224126). The searches returned 16,327 articles, of which 11 articles reporting on 10 studies were included. Two studies found that dietetic intervention significantly improved ED psychopathology, and three found that it did not. Three studies reported that dietetic input improved other psychopathological markers, and three reported that it did not. One consistent finding was that dietetic input improved body mass index/weight and nutritional intake, although only two and three studies reported on each outcome, respectively. A variety of instruments were used to measure each outcome type, making direct comparisons between studies difficult. Furthermore, there was no consistent definition of the dietetic components included, with many containing psychological components. Most studies included were also published over 20 years ago and are now out of date. Further research is needed to develop consistent dietetic guidelines and outcome measures; this would help to clearly define the role of each member of the multidisciplinary team, and particularly the role of dietitians, in ED treatment.

Abstract
Anorexia nervosa (AN) is characterised by disrupted and restrictive eating patterns. Recent investigations and meta-analyses have found altered concentrations of inflammatory markers in people with current AN. We aimed to assess nutrient intake in participants with current or recovered AN, as compared to healthy individuals, and explore group differences in dietary inflammatory potential as a possible explanation for the observed alterations in inflammatory markers. We recruited participants with current AN (n = 51), those recovered from AN (n = 23), and healthy controls (n = 49). We used the Food Frequency Questionnaire (FFQ), to calculate a Dietary Inflammatory Index (DII®) score and collected blood samples to measure serum concentrations of inflammatory markers. In current AN participants, we found lower intake of cholesterol, compared to HCs, and lower consumption of zinc and protein, compared to HC and recovered AN participants. A one-way ANOVA revealed no significant group differences in DII score. Multivariable regression analyses showed that DII scores were significantly associated with tumour necrosis factor (TNF)-α concentrations in our current AN sample. Our findings on nutrient intake are partially consistent with previous research. The lack of group differences in DII score, perhaps suggests that diet is not a key contributor to altered inflammatory marker concentrations in current and recovered AN. Future research would benefit from including larger samples and using multiple 24-h dietary recalls to assess dietary intake.

Abstract
PURPOSE To quantify the effects of a short-term (6-day) low carbohydrate (CHO) high fat (LCHF), and low energy availability (LEA) diet on immune, inflammatory, and iron-regulatory responses to exercise in endurance athletes. METHODS Twenty-eight elite male race walkers completed two 6-day diet/training phases. During phase 1 (Baseline), all athletes consumed a high CHO/energy availability (CON) diet (65% CHO and ~ 40 kcal·kg-1 fat free mass (FFM)·day-1). In phase 2 (Adaptation), athletes were allocated to either a CON (n = 10), LCHF (n = 8; <50 g·day-1 CHO and ~ 40 kcal·kg-1 FFM·day-1), or LEA diet (n = 10; 60% CHO and 15 kcal·kg-1 FFM·day-1). At the end of each phase, athletes completed a 25 km race walk protocol at ~75% VO2max. On each occasion, venous blood was collected before and after exercise for interleukin-6, hepcidin, cortisol and glucose concentrations, as well as white blood cell counts. RESULTS The LCHF athletes displayed a greater IL-6 (p = 0.019) and hepcidin (p = 0.011) response to exercise after Adaptation, compared to Baseline. Similarly, post-exercise increases in total white blood cell counts (p = 0.026) and cortisol levels (p < 0.001) were larger compared to Baseline following LCHF Adaptation. Decreases in blood glucose concentrations were evident post-exercise during Adaptation in LCHF (p = 0.049), whereas no change occurred in CON or LEA (p > 0.05). No differences between CON and LEA were evident for any of the measured biological markers (all p > 0.05). CONCLUSION Short-term adherence to a LCHF diet elicited small yet unfavorable iron, immune, and stress responses to exercise. In contrast, no substantial alterations to athlete health were observed when athletes restricted energy availability compared to athletes with adequate energy availability. Therefore, short-term restriction of CHO, rather than energy, may have greater negative impacts on athlete health.

Liver disease in obesity and underweight: the two sides of the coin. A narrative review. Eat Weight Disord 2021; 26:2097-2107.

Abstract
PURPOSE Malnutrition, whether characterized by not enough or too much nutrient intake, is detrimental to the liver. We herein provide a narrative literature revision relative to hepatic disease occurrence in over or undernourished subjects, to shed light on the paradox where both sides of malnutrition lead to similar liver dysfunction and fat accumulation. METHODS Medline, EMBASE, and Cochrane Library were searched for publications up to July 2020. Articles discussing the association between both chronic and acute liver pathology and malnutrition were evaluated together with studies reporting the dietary intake in subjects affected by malnutrition. RESULTS The association between overnutrition and non-alcoholic fatty liver disease (NAFLD) is well recognized, as the beneficial effects of calorie restriction and very low carbohydrate diets. Conversely, the link between undernutrition and liver injury is more complex and less understood. In developing countries, early exposure to nutrient deficiency leads to marasmus and kwashiorkor, accompanied by fatty liver, whereas in developed countries anorexia nervosa is a more common form of undernutrition, associated with liver injury. Weight gain in undernutrition is associated with liver function improvement, whereas no study on the impact of macronutrient distribution is available. We hypothesized a role for very low carbohydrate diets in the management of undernutrition derived liver pathology, in addition to the established one in overnutrition-related NAFLD. CONCLUSIONS Further studies are warranted to update the knowledge regarding undernutrition-related liver disease, and a specific interest should be paid to macronutrient distribution both in the context of refeeding and relative to its role in the development of hepatic complications of anorexia nervosa.

Abstract
Dietary intake requires attention in the treatment of both eating disorders and type 1 diabetes (T1D) to achieve optimal outcomes. Nutritional management of both conditions involves encouraging a wide variety of healthful foods in the context of usual cultural and family traditions. In recent times, low carbohydrate diets have seen a rise in popularity, both in T1D and in the general population. Low carbohydrate diets involve dietary restriction, although the extent depends on the level of carbohydrate prescription. Although dietary restriction is a known risk factor for eating disorders, there is limited literature on the impact of following a low carbohydrate diet on the development and maintenance of eating disorders in T1D. The aim of this review is to discuss the impact of dietary restriction on the development and treatment of eating disorders and propose considerations to enable optimum health outcomes in individuals with T1D, an at risk group. In order to achieve this, clarity regarding strategies that allow both flexibility in dietary intake and facilitate healthy eating behaviours, whilst achieving glycaemic targets, are required.

Abstract
OBJECTIVE The present study investigates the impact of psychosocial stress on chewing and eating behavior in patients with anorexia nervosa (PAN ). METHOD The eating and chewing behavior of PAN were examined in a standardized setting by means of a chewing sensor. These procedures encompassed n = 19 PAN , age, and gender matched to n = 19 healthy controls (HC). Food intake and chewing frequency were assessed in two experimental conditions: rest versus stress (via Trier Social Stress Test). To verify stress induction, two appraisal scales were employed. In addition, chronic stress, psychological distress and eating disorder symptoms were assessed. RESULTS In terms of food intake and chewing frequency, the results of the 2x2 ANOVA demonstrated a significant effect of condition and group. During stress, all participants demonstrated a higher chewing frequency and a decreased ingestion. In general, patients ate less at a lower chewing frequency (vs. HC). However, sample specific analyses demonstrated that the eating and chewing behavior of PAN remained unchanged regardless of the condition, except for their drinking. Food choices were comparable between the groups, but appetite values significantly differed. DISCUSSION The increase in chewing frequency in all participants during stress suggests that chewing might impact affect regulation, however, not specifically in PAN . Future research should clarify to what extent the normalization of chewing behavior could ameliorate ED-symptoms (incl. food intake) in PAN . The application of a chewing sensor could support this aim and future interventions.

Abstract
PURPOSE Due to the current dearth of literature regarding dietetic treatment for patients with an eating disorder (ED), no manualised dietetic interventions exist to enable the testing of dietetic treatments in this population. This paper aims to: (1) describe the rationale and development of a manualised dietetic intervention for adults undergoing concurrent psychological treatment for an ED; and (2) provide an overview of the feasibility testing of this intervention. METHODS Current best evidence to date for dietetic treatment in EDs was utilised to develop a manualised dietetic intervention for feasibility testing alongside outpatient psychological 'treatment as usual'. RESULTS The developed intervention consists of five, dietitian-delivered outpatient sessions: (1) getting started; (2) mechanical eating and dietary rules; (3) estimating portion sizes and social eating; (4) maximising your meal plan and meal preparation; and (5) review and treatment planning as well as pre- and post-intervention assessments. CONCLUSION This paper is intended as a resource for clinicians and researchers in the conduct of future studies examining dietetic treatment for patients with an ED. LEVEL OF EVIDENCE Level V, description of a new manualised, reproducible dietetic intervention.

Abstract
CONTEXT Eating disorders (EDs) are complex mental illnesses that require medical, psychological, and dietetic intervention to assist patients achieve recovery. OBJECTIVE Available evidence was reviewed regarding dietetic intervention for adult outpatients with an ED and the quality of this evidence was assessed. DATA SOURCES Systematic literature searches were conducted using 5 databases (MEDLINE, PreMEDLINE, EMBASE, CINAHL, PsycINFO) for studies comparing adults with an ED receiving a dietetic intervention with those receiving a psychological intervention alone, those receiving a combined dietetic and psychological intervention, or a control group. DATA EXTRACTION Literature searches returned 3078 results, with 10 articles reporting on 9 randomized controlled trials meeting the inclusion criteria. The quality of evidence was assessed using the Cochrane Risk-of-Bias tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. DATA ANALYSIS GRADE assessments for studies involving individuals with anorexia nervosa indicated very low quality of evidence for outcomes including weight, ED psychopathology and ED behaviors , and no studies measured nutritional changes. For studies conducted with participants with bulimia nervosa or binge eating disorder, only 1 study included a group receiving combined evidence-based psychological and dietetic intervention. A combined intervention produced moderate-quality evidence for lower attrition, greater abstinence from ED behaviors, and more meals eaten per week in comparison with a stand-alone psychological or dietetic intervention. CONCLUSIONS There is currently limited evidence to sufficiently assess the impact of incorporating dietetic interventions into outpatient treatment for adults with an ED; however, available evidence supports clinical practice guidelines that dietetic intervention should not be delivered as a stand-alone treatment. Additional methodologically sound studies in larger samples are required to fully inform dietetic treatment in EDs and incorporation of such interventions as part of a multidisciplinary treatment approach.

Abstract
OBJECTIVE Individuals with anorexia nervosa (AN) pursue low-fat, low-calorie diets even when in a state of emaciation. These maladaptive food choices may involve fronto-limbic circuitry associated with cognitive control, habit, and reward. We assessed whether high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left dorsolateral prefrontal cortex (DLPFC) influenced food-related choice behavior in patients with severe, enduring (SE)-AN. METHOD Thirty-four females with SE-AN completed a Food Choice Task before and after 20 sessions of real or sham rTMS treatment and at a 4-month follow-up. During the task, participants rated high- and low-fat food items for healthiness and tastiness and then made a series of choices between a neutral-rated food and high- and low-fat foods. Outcomes included the proportion of high-fat and self-controlled choices made. A comparison group of 30 healthy women completed the task at baseline only. RESULTS Baseline data were consistent with previous findings: relative to healthy controls, SE-AN participants showed a preference for low-fat foods and exercised self-control on a greater proportion of trials. There was no significant effect of rTMS treatment nor time on food choices related to fat content. However, among SE-AN participants who received real rTMS, there was a decrease in self-controlled food choices at post-treatment, relative to baseline. Specifically, there was an increase in the selection of tasty-unhealthy foods. DISCUSSION In SE-AN, rTMS may promote more flexibility in relation to food choice. This may result from neuroplastic changes in the DLPFC and/or in associated brain areas.

Abstract
BACKGROUND To date, research on the dietary patterns of individuals with potential orthorexic symptoms is lacking. This cross-sectional pilot study aimed to explore the feasibility of assessing dietary patterns with psychological traits and states of individuals with possible orthorexic tendencies. METHODS Dietary intakes of 10 individuals (two males and eight females) were assessed using 24-h recall. Mean age of participants was 28.3 years; mean body mass index was 21.2 kg m-2 . Nutrient intakes were compared with current dietary guidelines and the Eatwell Guide (Public Health England, 2016). Participants completed the ORTO-15, the Eating Attitude Test (EAT-26), the Obsessive-Compulsive Inventory-Revised edition (OCI-R), Paulhus's Spheres of Control (SoC), the Rosenberg's Self-Esteem Scale (RSES) and the Multidimensional Body-Self Relations Questionnaire (MBSRQ). RESULTS High levels of disparity across participants' psychometric scores and 24-h recall results were observed. There was no single pattern of self-imposed dietary restrictions among participants. Described dietary practices failed to meet the guidelines for several nutrients. CONCLUSIONS The results of this pilot study suggest that an extensive investigation of the diets of individuals with possible orthorexic tendencies in a large-scale study would contribute to the understanding of this condition. In addition, the use of multiple psychometric instruments is recommended for diagnosing orthorexic nervosa.

Casper RC. Might Starvation-Induced Adaptations in Muscle Mass, Muscle Morphology and Muscle Function Contribute to the Increased Urge for Movement and to Spontaneous Physical Activity in Anorexia Nervosa? Nutrients 2020; 12:nu12072060. [PMID: 32664448 PMCID: PMC7400818 DOI: 10.3390/nu12072060] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 07/07/2020] [Accepted: 07/07/2020] [Indexed: 02/07/2023] Open
Abstract
Severely undernourished and underweight anorexia nervosa (AN) patients typically remain active and mobile. Might such persistent physical activity in AN be supported by specific adaptations in muscle tissue during long term undernutrition? To identify potential differences, studies examining the effects of undernutrition on skeletal muscle mass, muscle morphology and muscle function in healthy humans and in AN patients were reviewed. Adjustments in muscle morphology and function in AN did not differ in substance from those in healthy humans, undernourished people, or undergoing semi-starvation. Loss of muscle mass, changes in muscle contractility and atrophy of muscle fibers (predominantly type II fibers) characterized both groups. Muscle innervation was unaffected. Work capacity in men in semi-starvation experiments and in females with AN declined by about 70% and 50%, respectively. Perceptions of fatigue and effort distinguished the groups: signs of general weakness, tiring quickly and avoidance of physical activity that were recorded in semi-starvation were not reported for AN patients. The absence of distinctive starvation-related adjustments in skeletal muscle in AN suggests that new methods, such as muscle gene expression profiles in response to deficient nutrient intake, and better knowledge of the central regulatory circuitries contributing to motor urgency will be required to shed light on the persistent mobility in AN patients.

Abstract
The aim of the study was to investigate the prevalence of, and attitudes toward, vegetarianism and veganism. We also assessed the association between vegetarianism/veganism and eating disorder, depressive, and somatic symptoms. A cross-sectional questionnaire survey in adults in Germany that was representative in terms of age, gender, and educational level was carried out. Data from 2449 adults (53.5% females) were included. Mean age was 49.6 (SD 17.1) years. A total of 5.4% of participants reported following a vegetarian or vegan diet. While the majority of participants agreed that vegetarian diets are healthy and harmless (56.1%), only 34.8% believed this to be true of vegan diets. The majority of participants also believed that a vegetarian (58.7%) or vegan (74.7%) diet can lead to nutritional deficiency. Female gender, younger age, higher education, lower body mass index (BMI), and higher depressive and eating disorder symptoms were found to be associated with vegetarianism/veganism. We did not find increased physical complaints in the group of vegetarians/vegans. Our results point toward a moderate prevalence of vegetarianism/veganism among the general population. Our findings suggest that health care professionals should keep eating disorder pathology, affective status in mind when dealing with individuals who choose a vegetarian/vegan dietary pattern.

Abstract
Introduction: Eating disorders (EDs) have increased globally in women of childbearing age, related to the concern for body shape promoted in industrialized countries. Pregnancy may exacerbate a previous ED or conversely may be a chance for improving eating patterns due to the mother's concern for the unborn baby. EDs may impact pregnancy evolution and increase the risk of adverse outcomes such as miscarriage, preterm delivery, poor fetal growth, or malformations, but the knowledge on this topic is limited. Methods: We performed a systematic review of studies on humans in order to clarify the mechanisms underpinning the adverse pregnancy outcomes in patients with EDs. Results: Although unfavorable fetal development could be multifactorial, maternal malnutrition, altered hormonal pathways, low pre-pregnancy body mass index, and poor gestational weight gain, combined with maternal psychopathology and stress, may impair the evolution of pregnancy. Environmental factors such as malnutrition or substance of abuse may also induce epigenetic changes in the fetal epigenome, which mark lifelong health concerns in offspring. Conclusions: The precocious detection of dysfunctional eating behaviors in the pre-pregnancy period and an early multidisciplinary approach comprised of nutritional support, psychotherapeutic techniques, and the use of psychotropics if necessary, would prevent lifelong morbidity for both mother and fetus. Further prospective studies with large sample sizes are needed in order to design a structured intervention during every stage of pregnancy and in the postpartum period.

Abstract
PURPOSE OF REVIEW This article reviews new research in the context of existing literature to identify approaches that will advance understanding of the persistence of anorexia nervosa. RECENT FINDINGS Neuroscience research in anorexia nervosa has yielded disparate findings: no definitive neural mechanism underlying illness vulnerability or persistence has been identified and no clear neural target for intervention has emerged. Recent advances using structural and functional neuroimaging research, as well as new techniques for applying and combining these approaches, have led to a refined understanding of changes in neural architecture among individuals who are acutely ill, have undergone renourishment, or are in recovery/remission. In particular, advances have come from the incorporation of computational and translational approaches, as well as efforts to link experimental paradigms with illness-relevant behavior. Recent findings converge to suggest abnormalities in systems involved in reward learning and processing among individuals with anorexia nervosa. SUMMARY Anorexia nervosa is associated with neurobiological abnormalities. Aberrant learning and reward processing may contribute to the persistence of illness. To better utilize new techniques to understand the neural mechanisms of persistent anorexia nervosa, it may help to distinguish stages of illness and to link neurobiology with maladaptive behavior.

Abstract
Fat restriction is a characteristic eating behavior among individuals with anorexia nervosa (AN), and laboratory meal studies demonstrate restricted fat intake among low-weight patients. The Geiselman Food Preference Questionnaire-I© (FPQ) is a validated self-report measure that yields a fat preference score (FPS). Prior research reported that patients with AN had a significantly lower FPS than did healthy control (HC) participants. The goal of the current study was to compare self-reported fat preference (FPS) to fat intake (multi-item meal (MIM) study) in low-weight ANs and HCs. Specific aims were 1) to determine if the FPS differed between ANs and HCs; 2) to determine if fat and energy intakes differed between ANs and HCs; and 3) to determine if the FPS was associated with fat and energy intakes in ANs and HCs. Forty-four female AN inpatients and 48 female HCs completed the FPQ and participated in a MIM study. Compared to HCs, ANs consumed less energy (469.1 ± 397.7 vs. 856.4 ± 346.8 kcal, p < 0.001), less fat (16.4 ± 20.4 vs. 36.7 ± 18.9 g, p < 0.001), and a smaller percentage of calories from fat (22.9 ± 13.8 vs. 36.6 ± 8.0%, p < 0.001) at the MIM. Compared to HCs, ANs also had a lower FPS (79.7 ± 27.4 vs. 102.3 ± 18.9, p < 0.001). The FPS was significantly and positively correlated with caloric intake (r = 0.481, p < 0.01), total fat (r = 0.453, p < 0.01), and the percentage of calories from fat (r = 0.37, p < 0.05) in ANs as well as in HCs (kcal: r = 0.583, p < 0.001; fat: r = 0.621, p < 0.001; % fat kcal: r = 0.601, p < 0.001). The FPS is related to objective measures of energy and fat intake in patients with AN as well as in healthy individuals.

Nutrients 2019; 11:nu11040792. [PMID: 30959831 PMCID: PMC6520973 DOI: 10.3390/nu11040792] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 03/27/2019] [Accepted: 04/01/2019] [Indexed: 12/18/2022] Open
Abstract
Introduction: Anorexia nervosa (AN) is a complex psychiatric disorder, which can lead to specific somatic complications. Undernutrition is a major diagnostic criteria of AN which can be associated with several micronutrients deficiencies. Objectives: This study aimed to determinate the prevalence of micronutrients deficiencies and to compare the differences between the two subtypes of AN (restricting type (AN-R) and binge-eating/purging type (AN-BP)). Methods: We report a large retrospective, monocentric study of patients hospitalized in a highly specialized nutrition unit between January 2011 and August 2017 for severe malnutrition treatment in the context of anorexia nervosa. Results: Three hundred and seventy-four patients (360 (96%) women, 14 (4%) men), age: 31.3 ± 12.9 years, Body Mass Index (BMI): 12.5 ± 1.7 kg/m2 were included; 253 (68%) patients had AN-R subtype while, 121 (32%) had AN-BP. Zinc had the highest deficiency prevalence 64.3%, followed by vitamin D (54.2%), copper (37.1%), selenium (20.5%), vitamin B1 (15%), vitamin B12 (4.7%), and vitamin B9 (8.9%). Patients with AN-BP type had longer disease duration, were older, and had a lower left ventricular ejection fraction (LVEF) (p < 0.001, p = 0.029, p = 0.009), when compared with AN-R type, patients who instead, had significantly higher Alanine Aminotransferase (ALT) and Brain Natriuretic Peptide (BNP) levels (p < 0.001, p < 0.021). In the AN-BP subgroup, as compared to AN-R, lower selenium (p < 0.001) and vitamin B12 plasma concentration (p < 0.036) were observed, whereas lower copper plasma concentration was observed in patients with AN-R type (p < 0.022). No significant differences were observed for zinc, vitamin B9, vitamin D, and vitamin B1 concentrations between the two types of AN patients. Conclusion: Severely malnourished AN patients have many micronutrient deficiencies. Differences between AN subtypes are identified. Micronutrients status of AN patients should be monitored and supplemented to prevent deficiencies related complications and to improve nutritional status. Prospective studies are needed to explore the symptoms and consequences of each deficiency, which can aggravate the prognosis during recovery.

Abstract
BACKGROUND The number of adolescent patients with anorexia nervosa is increasing. In addition, an increase in pre-adolescent patients with premenarchal onset has also been recognized. Detection of the disease in childhood and adolescence, however, is not always easy because the symptoms are not characteristic during this period. This study was performed to investigate detection of anorexia nervosa in children/adolescents by comparing energy and nutrient intake between patients with anorexia nervosa and healthy thin persons. METHODS The subjects consisted of 13 girls aged 14.4 ± 3.5 years with anorexia nervosa and 320 healthy girls aged 12.4 ± 1.3 years. Dietary intake was evaluated using a validated diet history questionnaire designed for children/adolescents. Daily energy and nutrient intake were expressed as a percentage of the age- and sex-matched reference amount. RESULTS Healthy lean (body mass index [BMI], <50th percentile) girls with an above-average score for desiring thinness had higher fat and lower cereal intake, and a trend of lower carbohydrate intake. In contrast, patients with anorexia nervosa, compared with thin (BMI <5th percentile) girls, characteristically had significantly lower energy, fat, zinc, vitamin C, and confectionery intake. CONCLUSIONS Lean girls with an above-average desire for thinness appear to restrict their energy intake by reducing their intake of carbohydrates such as cereals while maintaining a relatively high fat intake. In contrast, girls with anorexia nervosa avoided fat and had a preference for vegetables. This characteristic eating pattern could be a useful clue for detection of anorexia nervosa in thin children and adolescents.

Abstract
BACKGROUND Study was conducted to determine the effect of dietary zinc deficiency and supplementation on the spleen morphology. METHODS Pre-pubertal Wistar rats (40-50 g) were divided into two groups with 6 sub-groups each viz. zinc control (ZC, 100 μg/g zinc diet), pair fed (PF, 100 μg/g zinc diet), zinc deficient (ZD, <1 μg/g zinc diet, zinc supplementation control (ZCS), zinc supplementation pair-fed (PFS) and zinc supplementation deficient (ZDS, 100 μg/g zinc control diet). Experiments were set for 2- and 4-weeks followed by 4 weeks of zinc supplementation. RESULTS In the present study body weight and BMI decreased significantly along with incidence of splenomegaly as typified by the increased splenic index in deficient groups compared with that of respective control groups. Histopathological changes such as disorganization of red pulp, several infiltered lymphocytes, vacuolization, loss of cellularity, karyolysis, dissolution of matrix, indistinct differentiation between red and white pulp were evident in spleen of 2ZD and 4ZD group animals. Degeneration was more severe after 4 weeks of zinc deficiency as giant cells formation and hypertrophy were also evident. CONCLUSION The findings revealed that zinc deficiency causes growth retardation and splenomegaly. Degenerative and atrophic changes in rat spleen suggest reduced cellular defense potential which will have a direct effect on immunity. Zinc supplementation may prove to be beneficial as there were varying degrees of cellular recovery after cessation of zinc deficiency.

Abstract
PURPOSE OF REVIEW The persistent maladaptive eating behavior characteristic of anorexia nervosa (AN) can be understood as a learned habit. This review describes the cognitive neuroscience background and the existing data from research in AN. RECENT FINDINGS Behavior is habitual after it is frequently repeated and becomes nearly automatic, relatively insensitive to outcome, and mediated by dorsal frontostriatal neural systems. There is evidence for such behavior in AN, in which restrictive intake has been related to dorsal frontostriatal systems. Other neural and neurocognitive data provide mixed findings, some of which suggest disturbances in habit systems in AN. There are compelling behavioral and neural data to suggest that habit systems may underlie the persistence of AN. The habit model needs further research, via more direct behavioral hypothesis testing and probes of the development of habitual behavior. Investigation of the habit-centered model of AN may open avenues for the development of novel treatments.

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.

[PMID: 29331365 DOI: 10.1016/j.appet.2018.01.010] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2017] [Revised: 10/18/2017] [Accepted: 01/07/2018] [Indexed: 10/18/2022]
Abstract
Aberrations in eating patterns constitute a substantial public health burden. Computer-based paradigms that measure responses to images of foods are potentially useful tools for assessing food attitudes and characteristics of eating behavior. In particular, food choice tasks attempt to directly probe aspects of individuals' decisions about what to eat. In the Food Choice Task participants rate the healthiness and tastiness of a variety of food items presented one at a time. Next, participants choose for each food item whether they prefer to eat the item vs. a neutrally rated reference food item. The goal of the current study was to assess the stability and reliability of this Food Choice Task over time and with repeated testing. Secondary analyses were conducted using data from healthy volunteers in two separate studies that administered the task at two time points, separated either by several days or about a month. The overall reliability of the Food Choice Task across multiple administrations was assessed using intra-class correlation coefficients and the reliability of ratings of individual food items was assessed using kappa coefficients. The results indicated that test-retest reliability of the Food Choice Task in healthy volunteers was high at both shorter and longer test-retest intervals. In addition, the reliability of individual food item ratings was good for a majority of items. The proportion of healthy volunteers' high-fat food choices did not change over time in either of the two studies. Thus, the Food Choice Task is suitable for measuring food choices in studies with multiple assessment points. In particular, the task may be well suited to assess restrictive eating, a construct which it has been difficult to assess in experimental settings.

J Eat Disord 2018; 6:6. [PMID: 29619220 PMCID: PMC5878939 DOI: 10.1186/s40337-018-0192-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2017] [Accepted: 03/08/2018] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND There is limited evidence to inform nutrition and dietetic interventions for individuals with eating disorders even though it is recommended as an essential part of multidisciplinary management. There is minimal guidance, an absence of standardised nutrition educational material, and no research on how best to educate patients on healthy eating and how to achieve nutrition adequacy. Therefore the REAL Food Guide was developed. METHODS The REAL Food Guide is a pyramid with four layers and key nutrition messages beside each layer that was conceived to address gaps in nutrition education and intervention for individuals with eating disorders. Written and verbal consumer feedback was obtained from consumers receiving treatment regarding the acceptability and usefulness of the REAL Food Guide. A unique database was developed to reflect the types of foods and realistic portion sizes that patients are likely to select. This database was used for nutrition modelling to assess the nutrition adequacy of three meal patterns (meat containing, vegetarian and semi-vegan) for both weight maintenance and weight regain. Each meal pattern was compared to the Nutrient Reference Values for Australia and New Zealand. RESULTS Nutritional analysis demonstrated nutritional adequacy of meal patterns for energy, macronutrients and most micronutrients when the recommended number of serves from the REAL Food Guide were assessed. All meal patterns were adequate in micronutrients except for the semi-vegan meal pattern that was inadequate in vitamin D. Feedback from individuals with eating disorders demonstrates the nutrition education tool was acceptable to them as they felt it was more helpful for their recovery than general nutrition guidelines. CONCLUSION The REAL Food Guide is a comprehensive and user-friendly guide that clinicians can use to educate patients about components of a balanced and healthy diet. The guide can educate all eating disorder clinicians, including those who are new to the field, about the basics of nutrition. Clinicians using the guide can be confident that, if followed, patient's energy and nutritional requirements will be met and important nutrition education messages are reinforced, that are tailored to the beliefs and concerns of individuals with eating disorders.

Abstract
OBJECTIVE This case-control study aims to evaluate the oral health status and orofacial problems in a group of outpatients with eating disorders (ED)-either anorexia nervosa (AN) or bulimia nervosa (BN)-further focusing on the influence of vomit. MATERIALS AND METHODS Fifty-five women outpatients with AN or BN diagnosis were invited to participate, of which 33 agreed. ED outpatients and matched controls were submitted to a questionnaire and clinical oral examination. RESULTS Multivariate analysis identified a significantly higher incidence of teeth-related complications (i.e., tooth decay, dental erosion, and self-reported dentin hypersensitivity), periodontal disease, salivary alterations (i.e., hyposalivation and xerostomia), and oral mucosa-related complications in ED outpatients. Dental erosion, self-reported dentin hypersensitivity, hyposalivation, xerostomia, and angular cheilitis were found to be highly correlated with the vomiting behavior. CONCLUSIONS ED outpatients were found to present a higher incidence of oral-related complications and an inferior oral health status, compared to gender- and age-matched controls. Alterations verified within outpatients were acknowledged to be quite similar to those previously reported within inpatients, in both of nature and severity, thus sustaining that the cranio-maxillofacial region is significantly affected by ED, even in the early/milder forms of the condition, as expectedly verified within outpatients.

Abstract
Purpose To compare the nutritional intake of adolescents with eating disorders (EDs) to recommended Daily Values of macronutrients and micronutrients, using the Nutrition Data Systems for Research (NDSR); to determine if nutritional content varied among the different sub-types of EDs; and to use the Healthy Eating Index 2010 (HEI-2010) as a measurement of diet quality in this population. Methods Forty-six adolescents referred to an ED Program were recruited for inclusion in this study. A detailed 24-h dietary recall from each participant was obtained and a detailed nutritional analysis was generated, allowing for calculation of the HEI-2010. Descriptive statistics were calculated to determine baseline characteristics of the study population and to determine associations and differences between ED subtypes. Results Average daily caloric intake was below recommended values in the study population. Despite this, the distribution of macronutrients was within the ranges recommended for older children and adolescents by the Dietary Guidelines for Americans, 2010. Micronutrient content varied considerably. The study population had a mean HEI-2010 score of 60.1, falling within the "needs improvement" category. A majority of the participants had insufficient caloric intake for the HEI to be applicable. Conclusion Results suggest that adolescents with EDs have a surprisingly normal distribution of macronutrient intake. Although using a diet quality assessment tool such as the HEI-2010 has been helpful in analyzing overall diet quality in the general population, the restrictive caloric intake which characterizes the ED population prevents the utility of such a guide for most patients with EDs.

Abstract
OBJECTIVE Adolescents and women with anorexia nervosa (AN) are known to severely restrict total calorie and fat intake. However, data are limited regarding specific macronutrient intake associated with weight gain in AN. OBJECTIVE To prospectively investigate dietary macronutrient composition associated with weight gain in adolescent girls with AN. METHOD A prospective naturalistic study of 90 girls 12-18 years old; 45 with AN and 45 healthy normal-weight-controls over a 6-12-month period. Participants completed four-day food diaries and underwent body composition assessment using dual energy X-ray absorptiometry. Weight gain was defined as a ≥10% increase in body mass index (BMI) from baseline. RESULTS Baseline clinical characteristics did not differ between girls with AN who did not gain weight (AN-0) versus those who did (AN-1) over the following 6-12 month period except for percentage of calories from proteins (p = 0.046). At 6-12 month follow-up, AN-1 consumed a lower percentage of total calories from protein (p = .001), and a higher percentage of total calories from fat (p = .02) compared to AN-0. AN-1 had a significant increase in the percentage of total calories obtained from and poly-unsaturated-fatty acids (PUFA) (p = 0.006) compared to AN-0, between baseline and follow-up. Within the AN group, BMI at follow-up was associated positively with percentage of total calories obtained from fat, MUFA, and PUFA (p < .05) at 6/12 months, and inversely with the percentage of total calories obtained from carbohydrates and proteins (p = .03). DISCUSSION Consuming a greater proportion of total calories from fat is associated with weight gain in adolescent girls with AN.

Abstract
Studies comparing eating behaviors in individuals avoiding meat and other animal products to omnivores have produced largely inconclusive findings, in part due to a failure to obtain sufficiently large samples of vegan participants to make meaningful comparisons. This study examined eating and health behaviors in a large community sample of dietary vegans ("vegans"), compared to omnivores. Participants (n = 578, 80.4% female) completed an online questionnaire assessing a range of eating- and other health-related attitudes and behaviors. Vegans (62.0%, n = 358) and omnivores (38.1%, n = 220) were comparable in terms of demographics. Vegans scored significantly lower than omnivores the Eating Disorder Examination - Questionnaire (multivariate p < 0.001), a measure of pathological eating behavior. They also were more likely to consider themselves "healthy" (p < 0.001) and to prepare food at home (p < 0.001). Vegans more frequently consumed fruits, vegetables, nuts, beans and grains (all p < 0.001), and less frequently consumed caffeinated soft drinks (p < 0.001). There were no significant differences between vegans and omnivores on measures of eating styles, body mass index, smoking or exercise behaviors, or problems related to alcohol consumption. Effect sizes for comparisons on eating-related measures were generally small, with ηp2 ranging from <0.01 to 0.05; the size of effects for comparisons on measures of other health behaviors ranged from small to medium (Φ = 0.09 to 0.33 and ηp2 < 0.01 to 0.42). Taken together, findings suggest that ultimately, vegans do not differ much from omnivores in their eating attitudes and behaviors, and when they do, differences indicate slightly healthier attitudes and behaviors towards food. Similarly, vegans closely resembled omnivores in non-eating related health behaviors.

Abstract
Micronutrient status in Anorexia Nervosa (AN) has been poorly documented and previous data are often contradictory. We aimed to assess micronutrient status in a large population of AN patients. The relationships between micronutrient status and body composition were also determined. Anthropometric, biochemical parameters and body composition data were collected at referral in 153 patients with AN (28.5 ± 11 years). At least one trace element deficit was observed in almost half of patients; the most frequent was selenium deficit (40% of patients). At least one vitamin deficit was observed in 45.7% of patients, mostly vitamin A and B9. Albumin, transthyretin and CRP were within normal range in most patients. No correlations were found between body composition and micronutrient status. Our study suggests that micronutrient status is often altered in AN patients, which may contribute to neuropsychiatric dysfunction. Monitoring of micronutrients and correction of deficits should be included in the routine care of AN patients.

Abstract
OBJECTIVE The aim of the present study was to assess energy and nutrient intake in a group of women with restrictive AN (r-AN) compared with a control group. METHODS Thirteen r-AN patients and 13 healthy female controls completed 7-d food records. Intake of macro- and micronutrients was compared between the two groups as well as to the Dietary Reference Intake for the Italian Population (LARN) for specific ages. Additionally, the r-AN patients underwent indirect calorimetry for measuring resting energy expenditure (REE). RESULTS Total energy intake was significantly lower in the r-AN group than in controls (906 ± 224 vs 1660 ± 139, respectively; P < 0.01). Nutrient composition significantly differed, as well. Mean intake of sodium, phosphorus, and zinc was higher in controls than in the women with r-AN (P < 0.01), but neither group of women met LARN recommendations for potassium, calcium, or iron intake. With respect to vitamins, no significant differences were found for riboflavin or vitamins A, B12, or C between groups, whereas levels of other vitamins differed (P < 0.01). Both groups failed to meet the LARN recommendation for vitamin D intake; moreover, none of the r-AN patients met recommended intake levels of vitamin E, thiamine, niacin, and folate. CONCLUSIONS Intakes reported by r-AN patients did not meet requirements for most micronutrients evaluated in this study and, as expected, both energy needs and specific dietary patterns differed between groups. Therefore, a careful evaluation of food consumption should be recommended to reduce nutritional gaps in these patients. According to these preliminary observations, nutritional counseling, mainly focused on calcium and vitamin D intake, should be suggested for healthy women, as well.

Abstract
OBJECTIVE Individuals with anorexia nervosa (AN) restrict fat intake. The Geiselman Food Preference Questionnaire-I© (FPQ) is a validated self-report instrument that yields a fat preference score (>100 = high fat preference, <100 = low fat preference). The goal of the study was to assess the utility of the FPQ in patients with AN. SPECIFIC AIMS (1) to examine change in fat preference scores before and after weight restoration in hospitalized patients; and (2) to compare patients' scores before and after weight restoration to scores from healthy participants (HPs). METHOD The FPQ was completed by 88 patients and 115 HPs. RESULTS Compared with HPs, patients had significantly lower fat preference scores before (74.03 ± 32.03 vs. 102.93 ± 16.89, P < 0.001) and after (81.51 ± 26.89 vs. 102.92 ± 16.89, P < 0.001) weight restoration. Fat preference scores increased with weight gain (74.03 + 32.03 vs. 81.51 + 26.89, P < 0.01) but did not normalize in AN. DISCUSSION Acutely weight restored patients continue to endorse decreased preference for high fat foods. The FPQ may be a useful metric by which to assess improvements in diet during treatment.

Abstract
PURPOSE To evaluate whether adolescents with a positive score in a screening tool for possible eating disorders (ED) have a different diet intake in comparison with those with a negative score. METHODS Cross-sectional study performed in 235 adolescents (37.9 % boys) from Zaragoza (Spain). Age, gender, BMI, maternal education, nutrient intake (7-day record) and screening tool for detecting ED [sick control on fat food test (SCOFF)] were assessed. ANCOVA test was used to determine nutrient intake differences (namely energy, macronutrients and micronutrients) according to the SCOFF total score (SCOFF ≥2 indicates a possible case of ED). ANCOVA test was adjusted by age, maternal education and BMI. This research was based on data from the cross-sectional multicenter Alimentación y Valoración del Estado Nutricional en Adolescentes españoles (Feeding and Assessment of Nutritional status of Spanish Adolescents) study. RESULTS The proportion of adolescents with possible symptoms of ED was 21.7 %. Girls SCOFF high-scorers (SCOFF+) mean daily energy intake was significantly lower than in those SCOFF low-scorers (SCOFF-) (P < 0.001); however, in boys there was no difference. Both in girls and boys, there were no statistically significant differences according to SCOFF questionnaire for macronutrient intake, adjusted by daily energy intake. Concerning micronutrients, in girls with SCOFF+ sodium, potassium, phosphorus, iron, zinc, vitamin B2 and niacin intakes were significantly lower than in those with SCOFF-; however, in boys, there were no differences. CONCLUSIONS Adolescent girls with current possible symptoms of ED presented lower total energy intake and several micronutrients intake compared with their peers without ED.

Abstract
Eating disorders are associated with a range of abnormalities in eating behavior. Some individuals consume large amounts of non-caloric artificial sweeteners, suggesting abnormalities in appetitive responding. The current study aimed to quantify hedonic and motivating effects of artificial sweetener in individuals with and without an eating disorder. Two laboratory studies were conducted. Hedonic preference was estimated using the number of artificial sweetener packets (0-10) added to unsweetened cherry flavored Kool-Aid (study 1). Motivation to obtain sweetener was assessed by a progressive ratio (PR) work task (study 2). Ninety-three participants (25 anorexia nervosa restricting type (AN-R), 23 AN binge/purge type (AN-B/P), 20 bulimia nervosa (BN), and 25 normal controls (NC)) completed the study. No significant difference in hedonic preference was found among participant groups. Work completed at the PR task ranged from 0 to 9500 key-board presses. The AN-B/P group had a significantly higher breakpoint and performed significantly more work for sweetener compared to the BN and NC groups. Among AN-B/P and AN-R participants, the preferred number of Equal packets was significantly correlated with the breakpoint and total work. The increased amount of work for sweetener among individuals with AN-B/P supports an enhanced reward value of sweet taste in this population, and suggests that the characteristic food avoidance in AN cannot be accounted for by decreased reward value of all taste-related stimuli. This study also supports the novel application of a PR ratio task to quantify the motivating effect of sweet taste among individuals with an eating disorder.

Abstract
Anorexia Nervosa (AN) is characterized by the maintenance of an undernourished, or starved, state. Persistent restrictive eating, or the recurrent intake of a diet that is inadequate to sustain a healthy weight, is the central behavior maintaining AN. To understand this disturbance, we need to understand the neural mechanisms that allow or promote the persistent choice of inadequate caloric intake. While a range of neural disturbances have been reported in AN, abnormalities in systems relevant to reward processing and the development of habit systems have been consistently described in both structural and functional neuroimaging studies. Most recently, brain and behavior have been directly examined by investigating the neural underpinnings of restrictive food choice. These recent data suggest that, among individuals with AN, dorsal frontostriatal circuits play a greater role in guiding decisions regarding what to eat than among healthy individuals. This line of research attempts to leverage advances in the field of cognitive neuroscience to further our understanding of persistent maladaptive choices of individuals with AN, in the hope that such advances will help in the development of novel treatments for this potentially fatal disorder.

Abstract
OBJECTIVE In anorexia nervosa (AN), osteoporosis and osteopenia are common, which have been associated with low circulating levels of vitamin D (VitD) in other settings. We aimed to meta-analyze cross-sectional studies reporting on VitD parameters in patients with AN and healthy controls (HCs). METHOD Electronic PubMed search from database inception until December 31, 2013 and meta-analysis of cross-sectional studies comparing serum levels of 25-hydroxyvitamin D (25OH-D), 1,25-dihydroxyvitamin D (1,25OH-D) and dietary VitD between patients with AN and HCs, before or after VitD supplementation. We calculated random effects standardized mean differences (SMDs) ±95% confidence intervals (CIs) as effect size measures. RESULTS Out of 1,739 initial hits, 15 studies with a total of 927 participants (AN = 408 and HCs = 519) were meta-analyzed. In the unsupplemented state, both serum 25OH-D (studies = 4; n = 168; SMD = -0.43; 95%CI: -0.83 to -0.03; p = .03) and 1,25OH-D levels (studies = 4; n = 113; SMD = -1.06; 95%CI: -1.47 to -0.66; p < .00001) were significantly lower in AN than HCs. In AN patients treated with cholecalciferol supplementation, serum 25OH-D levels were significantly higher than in HCs (studies = 5; n = 449; SMD = 0.66; 95%CI: 0.01-1.31; p = .05). Paradoxically, despite lower 25OH-D and 1,25OH-D levels, AN patients reported similar intake of VitD compared to HCs (studies = 6; n = 314; SMD = 0.33; 95%CI: -0.16, 0.81; p = .19). DISCUSSION Although AN patients reported similar dietary VitD intake compared to HCs, AN patients had significantly lower 25OH-D and 1,25OH-D levels without supplementation. Conversely, supplementation with cholecalciferol fully normalized VitD serum levels. Future studies are needed to clarify the role of VitD supplementation in AN for improving bone health.

Abstract
People routinely make poor choices, despite knowledge of negative consequences. We found that individuals with Anorexia Nervosa, who make maladaptive food choices to the point of starvation, engaged the dorsal striatum more than healthy controls when making choices about what to eat, and that activity in fronto-striatal circuits was correlated with their actual food consumption in a meal the next day.

Abstract
Defects in experiencing disgust may contribute to obesity by allowing for the overconsumption of food. However, the relationship of disgust proneness and its associated neural locus has yet to be explored in the context of obesity. Thirty-three participants (17 obese, 16 lean) completed the Disgust Propensity and Sensitivity Scale-Revised and a functional magnetic resonance imaging paradigm where images from 4 categories (food, contaminates, contaminated food or fixation) were randomly presented. Independent two-sample t-tests revealed significantly lower levels of Disgust Sensitivity for the obese group (mean score = 14.7) compared with the lean group (mean score = 17.6, P = 0.026). The obese group had less activation in the right insula than the lean group when viewing contaminated food images. Multiple regression with interaction analysis revealed one left insula region where the association of Disgust Sensitivity scores with activation differed by group when viewing contaminated food images. These interaction effects were driven by the negative correlation of Disgust Sensitivity scores with beta values extracted from the left insula in the obese group (r = -0.59) compared with a positive correlation in the lean group (r = 0.65). Given these body mass index-dependent differences in Disgust Sensitivity and neural responsiveness to disgusting food images, it is likely that altered Disgust Sensitivity may contribute to obesity.

Abstract
Understanding nutrient intake of anorexia nervosa (AN) patients is essential for the treatment. Therefore, estimates of total energy and nutrient consumption were made in a group of young women (19 to 30 years) with restricting and binge purge subtypes of AN participating in an ecological momentary assessment study. Participants completed three nonconsecutive 24-hour diet recalls. Mean nutrient intakes were stratified by subtype and by quartiles of energy intake and compared to the age specific Dietary Reference Intake (DRI) levels, as well as to the reported intakes from the What We Eat In America (WWEIA) dietary survey 2011–2012. Reported intake was determined for energy, macronutrients, and micronutrients. The mean body mass index (BMI) for all participants was 17.2 ± 0.1 kg/m2. Reported nutrient intake was insufficient for participants in quartiles 1–3 of both AN subtypes when compared to the DRIs. Intake reported by participants in quartile 4 of both subgroups met requirements for most nutrients and even met or exceeded estimated energy needs. Counseling of AN patients should be directed to total food consumption to improve energy intake and to reduce individual nutritional gaps.

Abstract
Few studies are focused on the antioxidant status and its changes in anorexia nervosa (AN). Based on the hypothesis that renutrition improves that status, the aim was to determine the plasma antioxidant status and the antioxidant enzymes activity at the beginning of a personalized nutritional program (T0) and after recovering normal body mass index (BMI) (T1). The relationship between changes in BMI and biochemical parameters was determined. Nutritional intake, body composition, anthropometric, hematological and biochemical parameters were studied in 25 women with AN (19.20 ± 6.07 years). Plasma antioxidant capacity and antioxidant enzymes activity were measured. Mean time to recover normal weight was 4.1 ± 2.44 months. Energy, macronutrients and micronutrients intake improved. Catalase activity was significantly modified after dietary intake improvement and weight recovery (T0 = 25.04 ± 1.97 vs. T1 = 35.54 ± 2.60μmol/min/mL; p < 0.01). Total antioxidant capacity increased significantly after gaining weight (T0 = 1033.03 ± 34.38 vs. T1 = 1504.61 ± 99.73 μmol/L; p < 0.01). Superoxide dismutase activity decreased (p < 0.05) and glutathione peroxidase did not change. Our results support an association between nutrition improvement and weight gain in patients with AN, followed by an enhancement of antioxidant capacity and catalase antioxidant system.

Abstract
OBJECTIVE Inadequate intake and preference for low-calorie foods are salient behavioral features of Anorexia Nervosa (AN). The neurocognitive mechanisms underlying pathological food choice have not been characterized. This study aimed to develop a new paradigm for experimentally modeling maladaptive food choice in AN. METHOD Individuals with AN (n = 22) and healthy controls (HC, n = 20) participated in a computer-based Food Choice Task, adapted for individuals with eating disorders. Participants first rated 43 food images (including high-fat and low-fat items) for Healthiness and Tastiness; an item rated neutral on both blocks was then selected as the Reference item. On each of 42 subsequent trials participants were asked to choose between the food item presented and the Reference item. RESULTS The AN group was less likely to choose high-fat foods relative to HC, as evidenced both in multilevel logistic regression (z = 2.59, p = .009) and ANOVA (F(1,39) = 7.80, p = .008) analyses. Health ratings influenced choice significantly more in AN relative to HC (z = 2.7, p = .006), and were more related to Taste among AN (χ(2) = 4.10, p = .04). Additionally, taste ratings declined with duration of illness (r = -.50, p = .02). DISCUSSION The Food Choice Task captures the preference for low-fat foods among individuals with AN. The findings suggest that the experience of tastiness changes over time and may contribute to perpetuation of illness. By providing an experimental quantitative measure of food restriction, this task opens the door to new experimental investigations into the cognitive, affective, and neural factors contributing to maladaptive food choices characteristic of AN.
