Chronic stress can lead to weight gain through various mechanisms. It often increases the levels of cortisol, a hormone that can promote fat storage, particularly in the abdominal area. Stress may also influence dietary habits, leading to emotional or stress eating, where individuals gravitate toward unhealthy foods for comfort. Furthermore, increased stress can reduce motivation for physical activity, perpetuating a cycle of inactivity and weight gain. Managing stress through techniques like mindfulness, exercise, and adequate sleep is essential for preventing weight-related issues.
