The Role of Stress and Mental Health in Obesity

Obesity is a complex chronic condition with multifactorial causes. Among these, psychological stress and mental health have emerged as significant contributors to the development and maintenance of obesity in adults. Chronic stress can influence eating behaviors, metabolic processes, and lifestyle habits in ways that promote weight gain. Likewise, mental health issues, such as depression, anxiety, and poor emotional regulation, often intertwine with obesity, creating a vicious cycle. This opinion paper discusses the psychological mechanisms linking stress and obesity, including stress-induced eating and impaired self-regulation, and examines the role of mental health and emotional regulation in eating behaviors. Interventions addressing stress and psychological well-being—ranging from cognitive-behavioral therapy and mindfulness-based techniques to stress management and other therapeutic approaches—are explored as essential components of effective obesity treatment. The evidence suggests that incorporating stress reduction and mental health support into obesity interventions can improve outcomes. Ultimately, obesity management requires a holistic approach that includes not only diet and exercise, but also the crucial psychological dimensions of stress and emotional health.
