Stress hormones, primarily cortisol, can significantly affect weight gain by promoting fat storage, particularly in the abdominal region. Elevated cortisol levels often occur during periods of chronic stress, leading to increased appetite and cravings for high-calorie foods. This hormonal imbalance can alter metabolism, decreasing the body's ability to burn calories effectively. Furthermore, stress can impact motivation to exercise, creating a cycle that exacerbates weight gain. Managing stress through healthy coping mechanisms is essential for maintaining a balanced weight and overall well-being.
