Stress plays a significant role in weight gain through hormonal fluctuations and changes in appetite regulation. When under stress, the body releases cortisol, a hormone linked to increased hunger and cravings for high-calorie foods. This emotional eating can lead to consuming excess calories and reduced motivation for physical activity. Stress can also disrupt sleep, which further impacts weight management and metabolic health. Managing stress through healthy coping strategies is essential to prevent these cycles and promote better weight control.
