Stress and obesity are highly correlated, with stress playing an important role in fat gain and metabolic disturbances. Chronic stress affects weight gain by the elevations of the stress hormone, cortisol, which may increase hunger, lead to fat deposition--especially in the abdomen--and decrease insulin sensitivity. It is often observed that along with stress comes emotional eating and having a sedentary lifestyle, further contributing to the risk of becoming obese. Stress is also linked to impacts on metabolic syndrome, cardiac diseases, and hormonal health and wellness, which is another factor to consider in the prevention of obesity. Stress management techniques--such as mindfulness, physical activity, sleep, and nutrition--can tackle the stress experiences that influence weight or address the metabolic health consequences of stress. Overall, a better understanding of stress and obesity relationships will only enhance comprehensive prevention or treatment plans.
