High cortisol levels, often related to stress, can contribute to weight gain by promoting fat accumulation, particularly in the abdominal area. Elevated cortisol can increase appetite and cravings, leading individuals to consume more high-calorie foods. Moreover, stress-induced cortisol can negatively impact sleep, further disrupting metabolism and energy balance. Over time, these factors can result in unwanted weight gain, especially if combined with a lack of physical activity. Managing stress through lifestyle changes, such as exercise and mindfulness practices, is essential to maintain healthy cortisol levels and support weight management.
