The prevalence of obesity is on the rise, which significantly increases the burden on global healthcare expenditures and profoundly impacting both physical and mental health. It has become a major public health challenge that urgently needs to be addressed in todays society. Obesity is influenced by multiple factors, including stress, genetics, hormones, and neuroendocrine elements, with lifestyle and epigenetic changes also playing significant roles. Stress impacts various physiological systems, including the brain, memory, cognition, immune response, cardiovascular health, and endocrine function. It can also trigger obesity by affecting appetite regulation, reward sensitivity, and hormonal balance. Understanding the relationship between stress and obesity is crucial for developing effective interventions. Recent research highlights that stress significantly affects eating behaviors, leading to weight gain, while obesity can exacerbate stress and disrupt life balance. Effective interventions include mindfulness training, which improves self-awareness, positive emotions, and psychological flexibility, and reduces stress, anxiety, and depression. Stress management programs and physical activity are also beneficial for weight loss and overall health. However, the limitations of small sample sizes, short intervention periods, limited participant diversity, and reliance on self-reported measures may undermine the generalizability and accuracy of the findings of previous research. Future research should focus on larger, diverse samples, long-term studies, and incorporate both objective measures of stress and self-reported data to better understand and manage obesity and stress.
