Abstract
Health is regulated by homeostasis, a property of all living things. Homeostasis maintains equilibrium at set-points using feedback loops for optimum functioning of the organism. Imbalances in homeostasis causing overweight and obesity are evident in more than 1 billion people. In a new theory, homeostatic obesity imbalance is attributed to a hypothesized ‘Circle of Discontent’, a system of feedback loops linking weight gain, body dissatisfaction, negative affect and over-consumption. The Circle of Discontent theory is consistent with an extensive evidence base. A four-armed strategy to halt the obesity epidemic consists of (1) putting a stop to victim-blaming, stigma and discrimination; (2) devalorizing the thin-ideal; (3) reducing consumption of energy-dense, low-nutrient foods and drinks; and (4) improving access to plant-based diets. If fully implemented, interventions designed to restore homeostasis have the potential to halt the obesity epidemic.

This study examined the relationships between chronic stress, food cravings, and body mass index. A community-based sample of adults (N = 619) completed a comprehensive assessment battery and heights and weights were measured. Chronic stress had a significant direct effect on food cravings, and food cravings had a significant direct effect on body mass index. The total effect of chronic stress on body mass index was significant. Food cravings partially mediated the relationship between chronic s...

The objective of this study was to analyse emotional distress and concerns related to body image in 712 normal-weight and overweight adolescent girls. A total of 12.3 per cent of the normal-weight girls and 25 per cent of the overweight girls showed extreme weight-control behaviours. In normal-weight adolescents, their engagement in extreme weight-control behaviours was associated with high levels of somatic symptoms, a drive for thinness and control over eating. In overweight girls, high levels...

The foods we eat have substantial impact on our health, and excessive food intake is associated with numerous long-term health conditions. It is therefore essential to understand the factors influencing this crucial health behavior. Research has identified sleep problems as one such factor; however, little research has examined how sleep problems impact food intake. Using a multisystemic perspective, this article proposes a variety of ways in which sleep problems likely increase food intake and ...

This study explored self-compassion as a mediator between body dissatisfaction, social comparison based on body image and quality of life in 662 female college students. Path analysis revealed that while controlling for body mass index, self-compassion mediated the impact of body dissatisfaction and unfavourable social comparisons on psychological quality of life. The path model accounted for 33 per cent of psychological quality of life variance. Findings highlight the importance of self-compass...

We examined whether there is a relationship between trans fatty acid intakes and emotion regulation, mediated by positive or negative affect. Archival data on 1699 men and 3293 women were used to measure trans fatty acid intake at baseline, positive, and negative affects and emotion regulation at follow-up. Higher trans fatty acid intake related to subsequent difficulties with emotional awareness (p = 0.045), clarity (p = 0.012), and regulation strategies (p = 0.009). Affect mediated these relat...

This study aimed to investigate the relationship between Type D and dietary intake and to determine whether this relationship is mediated by coping. In a cross-sectional study, 187 healthy participants completed a self-report questionnaire measuring Type D personality, dietary intake and coping. Results showed that Type D was associated with maladaptive coping and significantly less healthy food intake, including more consumption of fat and sugar, and significantly less consumption of fruit and ...

This study tested a longitudinal motivation model for healthy eating in patients with cardiovascular disease, using self-determination and social-cognitive theories. A total of 513 patients completed measures of eating habits, global motivation, motivation for eating, self-efficacy for eating and life satisfaction, immediately after a major cardiac incident and at three times during a year (e.g. 2008–2009). Physiological indicators were measured to examine how they predicted the participants’ ph...

Eating habits are established early and are difficult to change once formed. This study investigated the role of caregiver–child attachment quality and its associations with high-caloric food consumption in a sample of middle socio-economic status children and adults, respectively. Survey data were collected from an online questionnaire administered separately to 213 (143 girls) children and 216 parents (adult sample; 180 women). Two studies showed that an insecure parental attachment, whether a...

The present longitudinal study investigated the incremental contribution of meaning in life to sustaining health-promoting behaviors, after controlling for well-being and health values among East-European adolescents (N = 456). Time 1 responses on presence of meaning, search for meaning, well-being, and health values were used to predict levels of healthy eating and physical activity 13 months later. All independent variables significantly predicted engagement in healthy eating and physical acti...

This study sought to examine whether two facets of weight self-stigma (fear of enacted stigma and self-devaluation) were associated with weight change and treatment engagement for 188 individuals participating in a 3-month online weight loss program. Fear of enacted stigma predicted less weight loss 3 months later after controlling for demographics, eating problems, and psychological symptoms. Self-devaluation did not predict weight loss. Neither weight self-stigma variable predicted engagement ...

BACKGROUND Not every eligible person opts for bariatric surgery. Body image concerns might be a reason to choose surgery. This case-control study evaluated differences in body image between a pre-bariatric surgery population and a weight-matched control group from the general population. We hypothesized that the pre-bariatric group would show less satisfaction with appearance, defined as a discrepancy between evaluating one's appearance as less attractive while attaching more importance to appea...

To reduce the spread of COVID-19, the World Health Organization and the majority of governments have recommended that the entire human population should 'stay-at-home'. A significant proportion of the population live alone or are vulnerable to mental health problems yet, in the vast majority of cases, individuals in social isolation have no access to mental healthcare. The only resource is people themselves using self-help, self-medication and self-care. During prolonged COVID-19 isolation, an i...
