Psychological Etiologies
The psychological effects of obesity can be deeply intertwined with emotional and behavioral factors, where psychological vulnerabilities may predispose individuals to obesity and vice versa. For instance, stress and emotional distress are significant contributors; individuals may turn to food as a coping mechanism for managing stress, leading to a cycle of emotional eating and weight gain.
[15][16] This behavior not only increases the risk of obesity but can also exacerbate feelings of guilt and shame, further impacting mental health.
[15] The stigma associated with obesity can lead to social isolation. low self-esteem and body image dissatisfaction, contributing to depressive symptoms and anxiety. This social isolation can create a feedback loop, where reduced social support and increased loneliness make it harder to engage in healthier behaviors or seek help.
[4][15][7][5][6] Additionally, body image dissatisfaction is a critical psychological factor; societal pressures to adhere to specific body standards can lead to a negative self-image and low self-esteem among individuals with obesity.
[15][7][5][6][4] This dissatisfaction can contribute to mood disorders, anxiety, and eating disorders. Childhood experiences and trauma can also play a role in shaping eating behaviors and self-esteem, affecting weight in the long term.
[15][5][6][4]
Psychological
Psychological factors play a significant role in the pathophysiology of the psychological effects of obesity. Moreover, body image dissatisfaction, low self-esteem, and maladaptive coping strategies are prevalent among those with obesity, where negative self-views related to body weight and shape can evoke shame, guilt, and social isolation, thereby increasing psychological distress.
[15]
At the forefront is the detrimental impact of negative body image and dissatisfaction, often intensified by societal beauty standards, which can precipitate low self-esteem, depression, and anxiety as individuals struggle with their self-perception and societal evaluations.
[15][5][6][27][4] The multifaceted stress associated with obesity, including health worries and societal stigma, challenges effective coping mechanisms, leading to maladaptive behaviors such as overeating.
[16] This is closely tied to emotional dysregulation, where individuals may resort to food for comfort amid emotional turmoil, fueling a cycle of emotional eating, weight gain, and further psychological distress.
[16]
Compounded by social isolation and stigma, discrimination across various contexts can induce loneliness and social withdrawal, heightening the risk for mood disorders.
[30] The relationship between obesity and increased instances of anxiety and depression is notably bidirectional; mental health disorders can drive behaviors that foster obesity, and conversely, obesity can escalate the risk of such disorders.
[32] The negative influence of obesity on self-esteem and self-efficacy, particularly regarding efforts to lose weight, can undermine motivation and intensify feelings of helplessness. At the same time, the overall quality of life suffers due to the physical limitations, health complications, and emotional distress associated with obesity, diminishing engagement in enjoyable activities and life satisfaction.
[34][31] Social withdrawal can also impact employability, affecting work experience, social skills, and the professional competencies necessary for securing employment, and mental health disorders may further obstruct an individual's ability to work, exacerbating social isolation, inactivity, and financial difficulties.

Epidemiology
There is a strong association between obesity and psychological issues, particularly mood disorders like depression. Several key findings from the research around the world:
- Individuals living with obesity have 18% to 55% increased odds of developing depression, while the risk of being classified as having obesity in people with depression is increased by 37% to 58%.[18]
- In an Austrian study, 2 out of 5 people who are overweight or obese are diagnosed with a psychiatric disorder, especially mood, anxiety, psychosis spectrum, or eating disorders.[19]
- The global burden of both obesity and mood disorders, including anxiety and depressive disorders, has increased substantially between 2010 and 2021. The age-standardized DALY rates for anxiety disorders and depressive disorders increased by 16.7% and 16.4% respectively during this period. Similarly, the age-standardized YLD rates for diabetes, which is primarily driven by the rise in type 2 diabetes and obesity, increased by 25.9% globally.[20]
The relationship between obesity and depression appears to be bidirectional and more substantial in women compared to men. In the USA, Younger individuals, non-Hispanic whites, and those with higher educational attainment show a stronger association between obesity and mood disorders.
[21][5] The relationship between obesity and depression is complex, with some studies finding depression as a risk factor for obesity, particularly atypical depression. In contrast, others show obesity increases the risk of depression. The impact of the obesity-depression combination on prognosis had mixed results, with factors like depression subtype, age, and sex influencing the association.
