The bidirectional relationship between mental health & obesity highlights the complex interactions between psychological well-being and metabolic health. Depression, anxiety, and stress-related disorders are frequently linked to overeating, emotional eating, and poor dietary choices, contributing to weight gain. Conversely, obesity-related stigma, social discrimination, and body image concerns can exacerbate mental health conditions, creating a cycle of distress and unhealthy behaviors. Neurobiological factors, including disruptions in dopamine signaling and stress hormone dysregulation, further connect obesity and mental health disorders. Integrated treatment approaches combining cognitive-behavioral therapy, mindfulness practices, and nutritional counseling offer effective strategies for breaking this cycle. Addressing both mental and physical health concurrently is essential for sustainable obesity treatment and improved quality of life.
