High stress levels can negatively impact eating habits by triggering emotional eating and cravings for unhealthy foods. When stress occurs, the body releases cortisol, which may increase appetite and desire for high-calorie, sugary foods. This behavior can lead to poor food choices, overeating, and ultimately weight gain. Understanding the connection between stress and eating can help individuals develop healthier coping mechanisms and strategies to manage stress without resorting to unhealthy eating patterns.
