The Relationship between Addictive Eating and Dietary Intake: A Systematic Review

(1) Background: Research suggests that certain foods may have addictive effects; however, no reviews have systematically appraised studies in this area. The aims of this review were to determine the nutrients, foods and dietary patterns associated with addictive eating. (2) Methods: Published studies up to November 2020 were identified through searches of 6 electronic databases. Eligible studies included those in in children and adults that reported dietary intakes of individuals with ‘food addiction’. (3) Results: Fifteen studies (n = 12 in adults and n = 3 in children/adolescents with Yale Food Addiction Scale defined ‘food addiction’) were included. Foods commonly associated with addictive eating were those high in a combination of fat and refined carbohydrates. Generally, intakes of energy, carbohydrates and fats were significantly higher in individuals with addictive eating compared to those without. (4) Conclusions: Due to the heterogeneity in study methodologies and outcomes across included studies, it is difficult to conclude if any specific foods, nutrients or dietary patterns facilitate an addictive process. Further research is needed to elucidate potential associations. However, present addictive eating treatment approaches could incorporate individualised dietary advice targeting foods high in fat and refined carbohydrates.

Very-Low-Calorie Ketogenic Diet: A Potential Treatment for Binge Eating and Food Addiction Symptoms in Women. A Pilot Study

Background: many patients who struggle to lose weight are unable to cut down certain ultra-processed, refined types of food with a high glycemic index. This condition is linked to responses similar to addiction that lead to overeating. A very-low-calorie ketogenic diet (VLCKD) with adequate protein intake could be considered a valid dietary approach. The aim of the present study was to evaluate the feasibility of a VLCKD in women with binge eating and/or food addiction symptoms. Methods: subjects diagnosed with binge eating and/or food addiction symptoms (measured with the Binge Eating Scale and the Yale Food Addiction Scale 2.0) were asked to follow a VLCKD with protein replacement for 5–7 weeks (T1) and a low-calorie diet for 11–21 weeks (T2). Self-reported food addiction and binge eating symptoms and body composition were tested at T0 (baseline) and at the end of each diet (T1 and T2 respectively); Results: five women were included in the study. Mean age was 36.4 years (SEM = 4.95) and mean BMI was 31.16 (SEM = 0.91). At T0, two cases of severe food addiction, one case of mild food addiction, one case of binge eating with severe food addiction, and one case of binge eating were recorded. Weight loss was recorded at both T1 and T2 (ranging from 4.8% to 11.6% of the initial body weight at T1 and from 7.3% to 12.8% at T2). No case of food addiction and/or binge eating symptoms was recorded at T2. Muscle mass was preserved. Conclusions: recent findings have highlighted the potential therapeutic role of ketogenic diets for the treatment of addiction to high-calorie, ultra-processed and high-glycemic food. Our pilot study demonstrates the feasibility of a ketogenic diet in women with addictive-like eating disorders seeking to lose weight.

The Prevalence of ‘‘Food Addiction’’ during the COVID-19 Pandemic Measured Using the Yale Food Addiction Scale 2.0 (YFAS 2.0) among the Adult Population of Poland

The announcement of the coronavirus pandemic by the World Health Organization (WHO), ongoing restrictions and isolation led to a break with the daily routine, and suspension of social contacts, but also imposed new challenges on the population related to maintaining healthy eating habits. The purpose of the study was to assess the prevalence of “food addiction” (FA) during the COVID-19 pandemic in Poland in relation to several variables including depression. The method of analysis was a questionnaire containing original questions and the Yale Food Addiction Scale 2.0 (YFAS). A total of 1022 Polish residents aged 18–75 participated in the study (N = 1022; 93.7% women, 6.3% men). The prevalence of FA during the COVID-19 pandemic measured with the YFAS 2.0 scale was 14.1%. The average weight gain during the pandemic in 39% of respondents was 6.53 kg. Along with the increase in the value of the BMI index, the intensity of “food addiction” increased in the study group. People with depression had statistically significantly more FA symptoms than healthy people. This work may motivate future research to evaluate the association and potential overlap of “food addiction” and problem eating behaviors during the pandemic and the obesity problem.

The impact of food addiction behaviours on the treatment of overweight students

The present study evaluated the association of food addiction (FA), the change of the BMI/AgeZ-score, and the consumption of ultra-processed foods in overweight students undergoing a 16-month, multicomponent intervention in the school environment. FA was investigated using the Yale Food Addiction Scale for Children and the dietary assessment was estimated using the Semi-quantitative Food Frequency Questionnaire in overweight 9- to 11-year-old students (BMI/ageZscore≥1) of both sexes at their baseline and after the intervention (n=120). Among the schoolchildren, 33.4% had FA in at least one of the two assessments. The analysis of mixed-effects models to assess the effect of the intervention and the change of the BMI/AgeZ-score between evaluations showed that the occurrence of FA influenced the maintenance of weight (time#FA, β=0.30, 95%CI=0.05 to 0.54), p=0.016. Weight loss was observed only in individuals who did not present FA (BMI/Age Z-score= −0.3). When evaluating the effect of the intervention and the dietary variables, we verified a reduction in the consumption of sugary milk-based drinks (−17 kcal, p=0.04) only in non-FA students at the end of the study. FA has been identified as an underlying factor with therapeutic relevance, and an enhanced understanding of FA can open new paths for the prevention and management of obesity.

Translation of the Chinese version of the modified Yale Food Addiction Scale 2.0 and its validation among college students

Background Obesity prevalence has substantially increased in China over the past decade. In China, over 1 in 7 individuals meet the criteria for overall obesity, and 1 in 3 meet the criteria for abdominal obesity, obesity has become a significant problem. Studies have shown that food addiction and obesity are inextricably linked. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a brief measurement for assessing food addiction. This study aimed to explore the structure of the Chinese version of the mYFAS 2.0 and assess the occurrence of food addiction in a sample of college students in Northeast China. Methods A cross-sectional design was conducted in a sample of 1099 undergraduate students in Northeast China. Participants completed the sociodemographic questionnaire, the Chinese version of the mYFAS 2.0, the Barratt Impulsiveness Scale (BIS-8), and the Self-Esteem Scale (SES) to test the hypothesis. Exploratory factor analysis and confirmatory factor analysis were performed to examine the underlying factor structure of the mYFAS 2.0. Two weeks later, 62 students who participated in the first test were recruited to evaluate the test–retest reliability. Results The Chinese version of the mYFAS 2.0 demonstrated adequate internal consistency, good test–retest reliability and satisfactory construct validity. The results of the confirmatory factor analysis found that the Chinese version of the mYFAS 2.0 demonstrated a good fit to the two-factor solution identified by the exploratory factor analysis and showed superior fit indices compared to the one-factor model. The prevalence of food addiction in our sample was found to be in line with rates observed in other Asian and Western samples. The mYFAS 2.0 symptom count scores were correlated with BMI, the idea of dieting to lose weight, the desire to overeat, low self-esteem, and impulsivity. Conclusion The results indicate that the Chinese version of the mYFAS 2.0 has good reliability and validity, and that it can be considered a tool to evaluate the addictive eating behaviours of undergraduate students.

The association between self-reported food addiction symptoms and obesity among adults: A cross-sectional study

Background: Overweight and obesity prevalence are still on the rise worldwide. Uncontrolled craving for specific foods has been associated with overweight/ obesity, categorizing them as possible abuse-related disorders with food addiction (FA) as their possible main phenotype. The association between FA and the onset of overweight/ obesity are still controversial, yet scientifically plausible and is the focus of many recent overweight/ obesity -related investigations. Objective: The current study was the first to examine the association of FA symptoms and obesity among young Bahraini adults. Methods: This study was designed using a cross-sectional research method recruiting a convenience adult samples of 654 aged 18-35 years. FA prevalence using Yale Food Addiction Scale (YFAS), sociodemographic, and anthropometric data, were collected using an on-line self-declared, semi-structured questionnaire. The descriptive results of the YFAS survey and the sociodemographic and anthropometric information were reported using descriptive statistics. Multiple regression test was utilized to analyze the correlations among examined factors. Results: A total of 124 (18.96%) participants met criteria for FA. Responses showed females had a slightly higher proportion of FA compared to the male participants). Results also showed no statistically significant association between various body mass index (BMI) categories and YFAS. For overweight participants, gender p = 0.018 appeared to be a significant predictor for BMI; and for obese participants, age p = 0.001 and sex p = 0.001 appeared to be significant predictors of BMI. Conclusions: No significant correlation was found between FA and BMI, age, and gender; on the other hand, age and gender were significant predictors for BMI.

Impact of COVID-19 Lockdown on Food Addiction in India

Food addiction (FA) has a long-term impact on the health of individuals. This study analyses the changes in FA and related behaviour in India in the wake of lockdown which started on 25th March 2020 as a response to the COVID-19 outbreak. This paper provides insight into the food consumption behavior of various segments of the population during this lockdown. It offers some new insights in this regard by establishing the relationship between a temporary pause in the consumption of palatable food and FA. This study was conducted between March and May 2020 in two stages. First, a quantitative study used the Yale Food Addiction Scale (YFAS) to identify food addicts from a sample of 150 respondents. In the second stage, in-depth telephone interviews were conducted with the food addicts; the responses were recorded, transcribed, and analysed to ascertain the changes in their overall consumption and addiction behavior towards palatable foods. This was done by conducting a thematic analysis with the help of the NVivo software where various tools like word cloud and cluster analysis were used. This study found that COVID-19 restrictions had significantly brought down the addiction to palatable food in India as the regular consumption chain had got broken during the lockdown. The consumption of palatable food is expected to remain low for a brief period after the lockdown due to hygiene issues like improper or lack of sanitization and cleanliness. However, in the long-run, the consumption of palatable food is expected to rise in India owing to its growing population, modernisation, increasing disposable income and changes in customer preferences. These findings have significant implications for the food, packaging and health industries as the changes in customer behavior will certainly impact them, and they need to duly change their strategy to adapt to the changes promptly.

Do Disordered Eating Behaviors Have an Effect on Food Addiction?

Objective: We aimed to evaluate the relationship between food addiction and uncontrolled eating, cognitive restraint, and emotional eating. Methods: We carried out this study with 1168 students (758 girls and 410 boys) studying at 7 different high schools in Ankara, Turkey. We used 3 measures. The first measure part assessed the participants’ demographic characteristics. We used 2 other validated measures, the Yale Food Addiction Scale and the Three-Factor Eating Questionnaire, to assess disordered eating behaviors. Results: No statistically significant difference was found between girls (12.9%) and boys (12%) in terms of food addiction (p = .67). We found that uncontrolled eating (p < .001), cognitive restraint (p = .007), and emotional eating (p < .001) scores were higher in individuals with food addiction (60.50±22.37; 38.39±24.41 and 57.42±28.49 respectively) than those without food addiction (40.17±24.74; 32.36±25.4 and 31.11±29.46 respectively). Furthermore, these eating behaviors increased the risk of food addiction in adolescents [Uncontrolled eating: OR: 1.02 (1.01-1.03); Cognitive Restraint: OR: 1.01 (1.00-1.02); Emotional Eating: OR: 1.016(1.009-1.024)]. Conclusions: Disordered eating behaviors can be seen more frequently among adolescents with food addiction compared to those without. In addition, these eating behaviors can increase the risk of food addiction relatively.
