Stress can significantly affect weight management by triggering emotional eating and increasing cravings for unhealthy foods. Elevated stress levels lead to increased production of the hormone cortisol, which is associated with increased appetite and weight gain, particularly around the abdominal area. Effective stress management techniques, such as exercise, mindfulness, and healthy coping strategies, can mitigate these effects by fostering a more balanced emotional state, ultimately aiding in healthier eating habits and weight control.
