The relationship of hedonic hunger with food addiction and obesity in university students

PURPOSE

In this study, it was aimed to evaluate the relationship of hedonic hunger with food addiction and obesity in university students.

METHODS

The research sample consists of 275 university students between the ages of 19-28 years. Body weight (kg), height (cm), waist and hip circumference (cm) were measured by applying a face-to-face questionnaire including descriptive characteristics of individuals, the Power of Food Scale (PFS), the Palatable Eating Motive Scale (PEMS) and the Modified Yale Food Addiction Scale (mYFAS) 2.0. Statistical analysis of the data was done with SPSS (Statistical Package for Social Sciences) 18.

RESULTS

In individuals, according to the mean PFS score the presence of food power-induced hedonic hunger was detected. While according to the mean PEMS score no motivational hedonic hunger was detected. According to the BMI classification the average scores of PFS (p = 0.002), PEMS (p = 0.009), and mYFAS 2.0 (p < 0.001) showed a gradual increase from underweight to obese. A weak positive correlation was found between BMI and PFS score (r = 0.238; p < 0.05) and PEMS score (r = 0.196; p < 0.05), respectively. The moderate positive correlation (r = 0.439 p < 0.001) was found between mYFAS 2.0 and the PEMS scores.

CONCLUSION

As a result, the presence of food-based hedonic hunger was determined in young individuals. A relationship was determined between food addiction and hedonic hunger caused by the motivation to consume delicious foods. Accordingly, hedonic hunger is related to food addiction and obesity in university students.

Relationship between Psychopathology and Sources of Meaning in Psychotherapeutically Treated Patients: A Naturalistic Cross-Sectional Analysis

INTRODUCTION

The experience of meaning seems to be crucial for psychic well-being. In the literature, there are reports of relationships between personality, illness, and life meanings. The objective of this study was to investigate types of experiences of meaning (meaningfulness, crisis of meaning, existential indifference) and their associations with some psychopathological categories in a clinical population.

METHODS

In a naturalistic and cross-sectional design, 56 German patients in outpatient psychotherapy (29 women, 27 men; mean age = 42.8 years, standard deviation = 13.8) were assessed by the Sources of Meaning and Meaning in Life Questionnaire (SoMe) Questionnaire (meaning of life, hedonism, eudaemonia). Psychopathology (Beck Depression Inventory (BDI), Clinical Global Impression scale, Symptom Checklist (SCL)-90), self-esteem (Rosenberg scale), neuroticism (NEO-Five-Factor Inventory), and suicidality (Suicide Behaviors Questionnaire Revised (SBQ-R)).

RESULTS

Three distinct groups concerning the experience of meaning emerged: meaningfulness (33.9%), crisis of meaning (21.4%), and, as the largest group, existential indifference (42.9%). Eudaemonia as well as the hedonistic SoMe variables of fun and wellness were shown to be inversely related to psychopathology such as suicide risk (SBQ-R), general symptom distress (SCL-90), and depressive symptomatology (BDI-II).

CONCLUSION

This study highlights the importance of a differential consideration of existential factors, sources of meaning and life orientations for psychopathology in mental health, which should be more considered in standard psychotherapeutic situations.

A Habit-Based Randomised Controlled Trial to Reduce Sugar-Sweetened Beverage Consumption: the Impact of the Substituted Beverage on Behaviour and Habit Strength

BACKGROUND

Excess sugar consumption has been linked to numerous negative health outcomes, such as obesity and type II diabetes. Reducing sugar-sweetened beverage (SSB) consumption may reduce sugar intake and thus improve health. The aim of the study was to test the impact of the potentially different rewarding nature of water or diet drinks as replacements for SSB, using a habit and implementation intention-based intervention.

METHOD

An online randomised, two-arm parallel design was used. One hundred and fifty-eight participants (mainly from the UK and USA) who regularly consumed SSBs (M_age = 31.5, 51% female) were advised to create implementation intentions to substitute their SSB with either water or a diet drink. Measures of SSB consumption, habit strength and hedonic liking were taken at baseline and at 2 months. Water or diet drink consumption was only measured at 2 months.

RESULTS

There was a large and significant reduction in SSB consumption and self-reported SSB habits for both the water and diet drink groups, but no difference between groups. There were no differences in hedonic liking for the alternative drink, alternative drink consumption and alternative drink habit between the two groups. Reduction in SSB hedonic liking was associated with reduced SSB consumption and habit.

CONCLUSION

This study demonstrates that an implementation intention-based intervention achieved substantial reductions in SSB consumption and habits. It also indicates that hedonic liking for SSBs and alternative drinks are associated with changes in consumption behaviour. Substituting SSBs with water or diet drinks was equally as effective in reducing SSB consumption.

A step in the journey to food waste: How and why mealtime surpluses become unwanted

This paper explores how and why Saudi householders designate mealtime leftovers as unwanted, thereby making them more likely to become waste. The paper argues that although over-provisioning is cited as one of the main antecedents for food waste, food becomes unwanted before it becomes waste and the designation of over-provisioned food as unwanted is an important but neglected driver of food waste. The study draws on in-depth interviews with 28 Saudi women to reveal four main reasons for the classification of leftovers as unwanted. First, food touched by others, such as plate leftovers, is perceived as unclean because it fosters feelings of disgust. The causes of this disgust are related to changes in social norms of eating. Second, clean leftovers are seen as less desirable for hedonistic reasons because they do not provide the same sensory eating experience as fresh food. Third, the rejection of leftovers might be related to the implications of rising levels of affluence for the attractiveness of leftovers. Lastly, food becomes unwanted as a result of social norms regarding eating home-cooked food outside the home. This highlights the possible influence of norms on the wider issue of food waste. These findings illustrate the circumstances in which food is categorized as unwanted and underline the significance of social and hedonistic factors. Such findings help us to better tackle the issue of food waste by providing in-depth insights into an important part of the journey between over-provisioning and food waste. The findings also strengthen the scarce literature on food waste in Arabic and other Islamic countries and highlight underlying normative and cultural aspects in such countries that are relevant to the issue of household food waste.

Self-Reported Hedonism Predicts 12-Month Weight Loss After Roux-en-Y Gastric Bypass

Introduction

Research regarding psychological risk factors for reduced weight loss after bariatric surgery has yielded mixed results, especially for variables measured prior to surgery. More profound personality factors have shown better promise and one such factor that may be relevant in this context is time perspective, i.e., the tendency to focus on present or future consequences. The aim of this study was to investigate the predictive value of time perspective for 12-month weight loss after Roux-en-Y gastric bypass surgery.

Methods

A total of 158 patients were included and completed self-report instruments prior to surgery. Weight loss was measured after 12 months by medical staff. Background variables as well as self-reported disordered eating, psychological distress, and time perspective were analyzed with regression analysis to identify significant predictors for 12-month weight loss.

Results

The mean BMI loss at 12 months was 14 units, from 45 to 30 kg/m². Age, sex, and time perspective could significantly predict weight loss but only male sex and self-reported hedonism were independent risk factors for reduced weight loss in the final regression model.

Conclusion

In this study, self-reported hedonistic time perspective proved to be a better predictor for 12-month weight loss than symptoms of disordered eating and psychological distress. It is possible that a hedonistic tendency of focusing on immediate consequences and rewards is analogous to the impaired delay discounting seen in previous studies of bariatric surgery candidates. Further studies are needed to identify whether these patients may benefit from extended care and support after surgery.

Pleasantness of olfactory and trigeminal stimulants in different Italian regions

Although individuals categorize odors according to their pleasantness, experience may also influence odor perception-a phenomenon that partially explains why different populations perceive odors differently. Italy, which comprises 20 regions, is characterized by very different cultures. In the present study, we investigated for the first time how Italian regional differences can affect odor perception. 254 healthy volunteers coming from northern, central, southern Italy, and Sicily, one of the two major Italian islands, were recruited in Padua, Rome, Naples, and Syracuse, respectively. Olfactory function was tested with Sniffin' Sticks identification subtest. Subjects who had a score in the range within the mean identification value ± 1 SD, in accordance with the age classes identified in the literature, were asked to judge the odor pleasantness of 20 substances. The hedonic tone of the odorants was categorized as pleasant, neutral, unpleasant, and very unpleasant. Some odorants were appreciated more in northern Italy than in the other parts of the country, whereas others were appreciated more in the south and in Sicily than in the north. Unpleasant odorants were judged less unpleasant in central Italy. Some odorants such as strawberry and vanilla were perceived similarly in all the regional areas. Our study indicates that in Italy, hedonic perception of odorants differs probably in relation with genetic, cultural, and environmental factors. Further investigation is needed to delve deeper into the factors that influence the quality odor perception amongst humans.

Higher and Lower Pleasures Revisited: Evidence from Neuroscience

This paper discusses J.S. Mill's distinction between higher and lower pleasures, and suggests that recent neuroscientific evidence counts against it.

Moral Preferences

In this brief response to Etzioni's paper we argue that satisfying one's preferences and seeking to live up to one's moral standards are not incompatible ways of living one's life, and that choosing to act morally need not involve self-sacrifice.

Flourishing and Posttraumatic Growth. An Empirical Take on Ancient Wisdoms

Considerations of well-being or flourishing include Maslow's and Rogers' concepts of self-actualisation and actualising tendency. Recent empirical findings suggest that only a modest proportion of the population might be considered to be flourishing. Separate findings focused upon the nature and determinants of post-traumatic growth identify it as comparable to flourishing, and facilitated by supported accommodation to the trauma. This can be understood as reflecting self-actualisation. Empirical findings such as these provide ontological stability to a set of phenomena that share much with ancient teachings extolling redemption through suffering. This framework challenges conventional healthcare policies and practices, but in ways that offer insights into how patient-centred approaches to chronic illness and disability might be better conceived and enabled. It also throws into doubt the rectitude of an economic model built around services and products designed to provide easy access to sources of immediate gratification.
