Purpose Understanding humans’ food intake practices is helpful in reducing health problems. The purpose of this study was to investigate the relationships between eating behaviours and binge eating and to examine the influence of sex and weight status on these relationships. Design/methodology/approach A total of seventy-eight participants (39 with overweight; mean age: 38.1 ± 6.3 years; body mass index [BMI]: 25 ± 5.7 kg/m2) underwent measurements of binge eating, eating styles and body compositions. A hierarchical multiple regression analysis was performed to predict binge eating as a function of eating styles and demographic variables. Findings Women presented higher levels of binge eating symptomatology and emotional eating than men. The analysis showed that age and gender did not emerge as important predictors of binge eating. In contrast, emotional and external eating and BMI were found to be important predictors of binge eating. The results indicate that higher emotional and external eating behaviour with higher BMI are important risk factors for binge eating in a non-clinical sample. Originality/value In this study, BMI was used as a causal factor rather than a consequence of deregulation of eating behaviour. An individual’s tendency to binge eat may be determined by BMI, emotional eating and sensitivity to environmental food stimuli. Understanding sex differences and causal relationships between eating behaviours is critical for the prevention and treatment of obesity and related health problems and for proper dietary management.

Food consumption involves several dimensions, being some of them directly associated with the consumers' characteristics. The interrelationships between these domains impact consumer behaviour for food choice and the consequent decisions for food consumption. In these frameworks, economic motivations are determinant. On the other hand, the scientific literature highlights that the economic-based stimuli to choose food is still underexplored. In this perspective, the objective of this study was to assess the main sociodemographic and anthropometric determinants of the economic motivations for food choice. For that, a questionnaire survey was carried out involving 11,919 respondents from 16 countries. A validated questionnaire was used, translated into the native languages in all participating countries, using a back-translation process. First, the information obtained was assessed through factor analysis to reduce the number of variables associated with the economic motivations and to identify indexes. After, and considering the indexes obtained as dependent variables, a classification and regression tree analysis was performed. As main insights, it is highlighted that the main determinants of the economic motivations are country of residence, age, gender, civil state, professional activity, educational level, living environment, responsibility for buying food, weight, height, body mass index, healthy diets and physical exercise practices. Additionally, the results also reveal that economic motivations may be associated with two indexes, one related to convenience attitudes and the other to quality concerns. Finally, the younger persons and the women are the social groups more concerned with healthy diets and food quality. In conclusion, this work confirmed that food choice is to a high extent influenced by several sociodemographic and behavioural factors.

This work intended to explore some motivations that influence people’s eating habits towards sustainability. This was an observational, cross-sectional study, carried out by questionnaire survey on a non-probabilistic sample of 10,067 participants from 13 countries (Argentina, Brazil, Croatia, Greece, Hungary, Latvia, Lithuania, Poland, Portugal, Serbia, Slovenia, Romania and United States). Results indicated that people prefer fresh local foods from the season, being important because it allows transportation and storage to be reduced, which in many cases implies refrigeration systems and consequent energy expenditure. Although people avoid food waste at home, the awareness for the waste at restaurants still needs to be improved. Consumers seem to prefer foods that have been produced and packed in sustainable ways but still give importance to the package—understandable for food products. The results also indicated significant differences in the food choice motivations between groups for all sociodemographic variables tested (age, sex, marital status, education, professional area, living environment and country), but the association was high only for variable country. Additionally, a tree classification analysis allowed to identify the relative importance of the influential variables on the sustainable food choices, with country being the most important, followed by age and sex. Additionally, discriminant function analysis allowed establishing a model for the relation between country and six variables accounting for preservation of biodiversity, respect for life, save natural resources, save energy, reduce industrial pollution and minimal packaging. Although with some limitations, this study brings valuable insight into some aspects linked with sustainable food choices on a number of countries and how people shape their food choices according to some sustainability issues.

Introduction The objective was to develop and validate an instrument that measures different determinants of people’s food choices and simultaneously accounts for a variety of factors: health, emotions, price and availability, society and culture, environment and politics, and marketing and advertising. Methods This is a cross-sectional study focusing on food choice determinants. It was carried out in 16 countries in 2017 and 2018. This study included 11,960 volunteer adult participants from different countries. The data was validated using Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM). Results Validation using CFA with SEM revealed that multi-factor modelling produced first- and second-order models that could be used to define the EATMOT scale, the first presenting better fitting indices, with the goodness-of-fit and comparative-fit indices very close to 1, as well as root-mean-square-error-of-approximation, root-mean-square-residual and standardised-root-mean-square-residual at practically zero. Conclusion The validated EATMOT scale guarantees confidence in the information obtained through this instrument, and can be used in future studies to better understand food choice determinants in different geographical areas and help plan strategies to improve healthy eating patterns and diminish the burden of non-communicable diseases.

Many aspects linked to personal characteristics, society and culture constitute some of the motivators that drive food choice. The aim of this work was to determine in what extent the eating behaviors of individuals are shaped by six different types of determinants, namely: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials. This is a descriptive cross-sectional study, involving a non-probabilistic sample of 11,960 participants from 16 countries. The objective of this work was to validate the questionnaire, so as to make it suitable for application in different contexts and different countries. For that, six scales were considered for validation by confirmatory factor analysis with structural equation modelling. The obtained results showed that the six individual scales evaluated presented good or very good fitting indices, with saturation in goodness-of-fit index in all cases. The values of chi-square ratio were 6.921 (for health), 0.987 (environment), 0.610 (emotions) and 0.000 in the remaining cases (convenience, society, marketing). Furthermore, the fit was perfect, with saturation for all indices, in three of the six models (convenience, society and marketing). The results of this wok allowed the validation of the six scales, and the assessing of different types of factors that can influence food choices and eating behaviors, namely in the categories: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials.

This study aimed at investigating the influence of some sociodemographic factors on the eating motivations. A longitudinal study was carried conducted with 11960 participants from 16 countries. Data analysis included t-test for independent samples or ANOVA, and neural network models were also created, to relate the input and output variables. Results showed that factors like age, marital status, country, living environment, level of education or professional area significantly influenced all of the studied types of eating motivations. Neural networks modelling indicated variability in the food choices, but identifying some trends, for example the strongest positive factor determining health motivations was age, while for emotional motivations was living environment, and for economic and availability motivations was gender. On the other hand, country revealed a high positive influence for the social and cultural as well as for environmental and political and also for marketing and commercial motivations.

Background: Many risk factors lead to opioid use and drug-related problems. One of the challenges to understand behavioural factors, drug problems and psychopathology is to identify biological markers that are suitable for research on broad substance abuse and dependence involving human participants. Aims: The study has examined the relationships between the self-reported childhood history of trauma, parental bonding, psychopathology, impulsivity, current resiliency, two neuropeptides, possible markers of behaviour and emotion regulation, and severity of drug-related problems. Methods: One hundred and sixty-seven individuals with a history of opioid use completed questionnaires. Serum neuropeptide Y (NPY) and substance P (SP) levels were analysed. Moderating and mediating relationships between variables were examined using structural equation modelling (SEM). Results: Antisocial features, depression, impulsivity, SP, NPY, emotional neglect and resilience are associated with severity of drug-related problems. SP is associated with antisocial personality traits. Conclusions: The novelty of this study is the proposed possible link between biochemical markers, antisocial features and behavioural and emotional regulation. Serum NPY and SP levels have a potential to be used as a biomarker in opioid users before and in the treatment process to account for interactions between biological vulnerabilities and childhood risk factors in predicting behavioural adjustment and more severe drug-related problems.

Individuals with long-term chronic body image dissatisfaction may experience excessive stress and negative cognitions and feelings. Changes in negative cognition about body image are often reported as outcomes of obesity treatment. In turn, body image dissatisfaction also influences behavioural adherence and success in weight loss. The purpose of the present study was to elucidate psychological changes during 6 months of lifestyle behaviour intervention and the association of these changes with actual weight loss. The study examined associations between body image dissatisfaction and obesity treatment-related variables among 33 overweight and obese adults (age = 38.9 ± 6.5 years) participating in a 6-month diet and exercise weight loss intervention. Measurements of body image dissatisfaction and anthropometric variables were taken at baseline and after 6-months. Significant improvements were observed in all physical variables (e.g. weight, percentage of body fat mass, waist and hip circumference) after intervention. Body image dissatisfaction improved significantly over the treatment, and these changes were associated with changes in obesity indicators. Changes in weight and body image probably influence each other dynamically. Results from this study support the inclusion of cognitive intervention aimed at improving body image in weight management programs.

Objectives. Obesity and overweight are chronic disorders of multifactorial origin that are characterized by high oxidative status and by chronic activation of macrophages in peripheral tissues. Effective therapeutic approaches to lower inflammation and oxidative stress are currently of general interest. Royal jelly (RJ) is a functional food with a broad range of pharmacological activities, mainly used by healthy individuals or borderline patients to protect themselves against disease onset. The objective of this randomized, double-blind, placebo-controlled trial was to investigate the effects of RJ supplementation on metabolic profile and oxidative and inflammatory parameters in asymptomatic overweight adults, considered at an early stage of developing metabolic syndrome. Material and Methods. The experimental group (n=30) was given RJ and the control group (n=30) was provided with a placebo for eight weeks. Anthropometric, biochemical parameters, biomarkers of oxidative stress, and inflammation were assessed at baseline, after 4 and 8 weeks of the intervention, and after additional 2 weeks of follow up. Results and Conclusion. Compared with the placebo, RJ supplementation demonstrated a statistically significant decrease in total cholesterol (6.7%; p=0.041) and inflammatory marker C-reactive protein (19%; p=0.027), whereas significant increases were observed in anti-inflammatory marker adiponectin (34%; p=0.011), endogenous antioxidants bilirubin (35%; p=0.002) and uric acid (5%; p=0.018), total antioxidant capacity in serum (54%; p=0.005), and leptin (17%; p=0.025). The present study demonstrated positive effects of RJ administration on lipid profile, satiety, inflammation, and antioxidant capacity in overweight adults. Therefore, our study supports the benefits of RJ supplementation for the improvement of human health.

The ketogenic diet (KD) is being increasingly promoted as a strategy to fight obesity. Although the KD is effective for weight loss and weight control, comprehensive determination of its relationship with biochemical, physiological and psychological changes is still largely unexplored. We hypothesized that a 12-week KD (12KD) would significantly affect body weight, physical performance, cognitive function, eating behaviors, the metabolic and hormonal profile in obese adults, although differently in males and females. In an uncontrolled intervention, 35 sedentary obese adults (13 males, 25 females), aged 37 ± 7 y with a BMI 36.1 ± 5.6 kg/m2 underwent a 12KD between March 2017 and June 2017 at the University of Primorska. The 12KD resulted in decreased appetite, significant weight loss of participants (−18 ± 9 kg males vs. -11 ± 3 kg females; P < .001), decreased emotional and external eating (P < .001 for both), increased body image satisfaction (P < .001) and improved physical performance (P < .001). Biochemically, a significant drop in glucose (P = .026), and a significant increase in LDL-cholesterol (P = .031), CRP (P = .007), and BDNF (P = .035) were observed in the first two weeks; then, all listed parameters returned to baseline. On the other hand, a significant reduction in insulin (P < .001) and leptin levels (P < .001), and a significant increase in adiponectin (P = .008) and NPY (P = .009) were detected throughout the duration of the 12KD. Our results show the efficacy of the 12KD on weight loss, physical performance, cognitive function, eating behaviors and metabolic profile. However, the long-term effects of a KD on these outcomes needs to be further studied before general recommendations can be made.

Background: This study has examined the relationships and interactions between serum brain-derived neurotrophic factor (BDNF) levels, BDNF Val66Met polymorphism and self-reported risk-taking behaviour in individuals with a history of heroin use undergoing outpatient treatment in comparison to healthy individuals. Methods: We enrolled 167 heroin users and 86 healthy subjects and examined serum BDNF levels, Val66Met polymorphism, and personal characteristics using Connor Davidson Resilience Scale, Risk-taking (RT) propensity questionnaire, and Personality Assessment Inventory. Results: Heroin users had significantly higher serum BDNF levels than controls. In addition, serum BDNF levels were significantly higher in Val/Val carriers than in Met/Val or Met/Met in all recruited subjects. Furthermore, a stepwise multiple regression analysis of serum BDNF levels as a dependent variable with related factors showed that in heroin users, Alcohol Use Disorder Identification Test score, anxiety and RT score were found as independent contributors to serum BDNF levels. When performing gene-environment interaction it was additionally found that heroin users with self-reported high risk-taking behaviour had significantly lower levels of serum BDNF among heroin users with the Met allele. Conclusions: These results indicate that genetic variant Met66 decreased the serum BDNF levels in combination with self-reported risk-taking propensity among heroin users. If results of future work confirm the influence of this combined effect between neurotrophic genotype and risk-taking behaviour, 66Met carriers might require higher levels of intervention to overcome their drug use pattern and risky behaviour.

Chili and its main active ingredient capsaicin have been shown to induce several favorable biological activities. In the present study we have tested the effect of three chili sauces mimicking popular commercially available chili sauces with an increasing amount of capsaicinoids on a broad range of serum biochemical markers in thirty healthy subjects. We show that in the region where daily use of chili is traditionally low, moderate consumption of 4.4 mg of capsaicinoids per day has beneficial health effects, such as decrease in glucose level, LDL cholesterol and C-reactive protein. However, when a product with higher daily dose of capsaicinoids (16.7 mg/day) was consumed, those effects were lost. Considering that biochemical marker levels returned to the initial levels after a week-long wash-out period, we suggest that regular intake of moderate amounts of chili product would be most profitable.

Body dissatisfaction may play some role in the pathophysiology of chronic diseases. This study examined relations between body dissatisfaction and circulating levels of inflammatory biomarkers C-reactive protein, tumour necrosis factor-α, interleukin-6 and anti-inflammatory adiponectin, and to explore positive changes in relevant lifestyle behaviour after these associations. A total of 33 asymptomatic overweight men and women were evaluated at the baseline and after a 6-month lifestyle behaviour intervention. Body dissatisfaction emerged as an important predictor of pro- and anti-inflammatory biomarkers and may promote the production of inflammatory cytokines by reducing the level of anti-inflammatory and increasing the level of pro-inflammatory cytokine production.

Low-grade systemic inflammation due to obesity is considered to be the key link between obesity and obesity-related disorders. The hypothesis was tested that significant alterations in inflammatory markers and adipokines would occur over a multidisciplinary intervention and that these changes might also be important for improvement of cardiovascular risk factors. Thirty-tree overweight adults completed a 6-month multidisciplinary intervention program to evaluate the effects of a personalized dietary program based on the individual's resting metabolic rate (RMR) on anthropometric parameters, aerobic and anaerobic capabilities, metabolic profile, inflammation, and body image satisfaction. Body composition, physical activity, anaerobic capabilities, RMR, metabolic profile, and low-grade inflammation were measured. Diet composition and body image dissatisfaction were also assessed. After 6 months of multidisciplinary intervention the participants showed significantly decreased body weight, waist circumference (WC), and the inflammatory markers tumor necrosis factor-α, C-reactive protein, and visfatin. They also showed increased anti-inflammatory adiponectin and consequently decreased serum insulin, HOMA-IR, and total cholesterol. The important findings of the study were that reduction of sugars and saturated fatty acids in the diet, coupled with an increase in exercise, significantly correlated with reduction of WC and body mass index. In addition, positive correlations between ∆ BMI, ∆ WC, ∆ trunk fat, inflammation, and cardiovascular risk factors were demonstrated. Weight loss in combination with increased physical activity, a negative energy balance, and diet adjustment was associated with lower inflammation and consequently with lower cardiovascular risk factors.
